+
+## Tutorial
+
+Bubble Tea is based on the functional design paradigms of [The Elm
+Architecture][elm], which happens to work nicely with Go. It's a delightful way
+to build applications.
+
+This tutorial assumes you have a working knowledge of Go.
+
+By the way, the non-annotated source code for this program is available
+[on GitHub][tut-source].
+
+[elm]: https://guide.elm-lang.org/architecture/
+[tut-source]: https://github.com/charmbracelet/bubbletea/tree/main/tutorials/basics
+
+### Enough! Let's get to it.
+
+For this tutorial, we're making a shopping list.
+
+To start we'll define our package and import some libraries. Our only external
+import will be the Bubble Tea library, which we'll call `tea` for short.
+
+```go
+package main
+
+// These imports will be used later on the tutorial. If you save the file
+// now, Go might complain they are unused, but that's fine.
+// You may also need to run `go mod tidy` to download bubbletea and its
+// dependencies.
+import (
+    "fmt"
+    "os"
+
+    tea "github.com/charmbracelet/bubbletea"
+)
+```
+
+Bubble Tea programs are comprised of a **model** that describes the application
+state and three simple methods on that model:
+
+- **Init**, a function that returns an initial command for the application to run.
+- **Update**, a function that handles incoming events and updates the model accordingly.
+- **View**, a function that renders the UI based on the data in the model.
+
+### The Model
+
+So let's start by defining our model which will store our application's state.
+It can be any type, but a `struct` usually makes the most sense.
+
+```go
+type model struct {
+    choices  []string           // items on the to-do list
+    cursor   int                // which to-do list item our cursor is pointing at
+    selected map[int]struct{}   // which to-do items are selected
+}
+```
+
+### Initialization
+
+Next, we’ll define our application’s initial state. In this case, we’re defining
+a function to return our initial model, however, we could just as easily define
+the initial model as a variable elsewhere, too.
+
+```go
+func initialModel() model {
+	return model{
+		// Our to-do list is a grocery list
+		choices:  []string{"Buy carrots", "Buy celery", "Buy kohlrabi"},
+
+		// A map which indicates which choices are selected. We're using
+		// the  map like a mathematical set. The keys refer to the indexes
+		// of the `choices` slice, above.
+		selected: make(map[int]struct{}),
+	}
+}
+```
+
+Next, we define the `Init` method. `Init` can return a `Cmd` that could perform
+some initial I/O. For now, we don't need to do any I/O, so for the command,
+we'll just return `nil`, which translates to "no command."
+
+```go
+func (m model) Init() tea.Cmd {
+    // Just return `nil`, which means "no I/O right now, please."
+    return nil
+}
+```
+
+### The Update Method
+
+Next up is the update method. The update function is called when ”things
+happen.” Its job is to look at what has happened and return an updated model in
+response. It can also return a `Cmd` to make more things happen, but for now
+don't worry about that part.
+
+In our case, when a user presses the down arrow, `Update`’s job is to notice
+that the down arrow was pressed and move the cursor accordingly (or not).
+
+The “something happened” comes in the form of a `Msg`, which can be any type.
+Messages are the result of some I/O that took place, such as a keypress, timer
+tick, or a response from a server.
+
+We usually figure out which type of `Msg` we received with a type switch, but
+you could also use a type assertion.
+
+For now, we'll just deal with `tea.KeyMsg` messages, which are automatically
+sent to the update function when keys are pressed.
+
+```go
+func (m model) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
+    switch msg := msg.(type) {
+
+    // Is it a key press?
+    case tea.KeyMsg:
+
+        // Cool, what was the actual key pressed?
+        switch msg.String() {
+
+        // These keys should exit the program.
+        case "ctrl+c", "q":
+            return m, tea.Quit
+
+        // The "up" and "k" keys move the cursor up
+        case "up", "k":
+            if m.cursor > 0 {
+                m.cursor--
+            }
+
+        // The "down" and "j" keys move the cursor down
+        case "down", "j":
+            if m.cursor < len(m.choices)-1 {
+                m.cursor++
+            }
+
+        // The "enter" key and the spacebar (a literal space) toggle
+        // the selected state for the item that the cursor is pointing at.
+        case "enter", " ":
+            _, ok := m.selected[m.cursor]
+            if ok {
+                delete(m.selected, m.cursor)
+            } else {
+                m.selected[m.cursor] = struct{}{}
+            }
+        }
+    }
+
+    // Return the updated model to the Bubble Tea runtime for processing.
+    // Note that we're not returning a command.
+    return m, nil
+}
+```
+
+You may have noticed that <kbd>ctrl+c</kbd> and <kbd>q</kbd> above return
+a `tea.Quit` command with the model. That’s a special command which instructs
+the Bubble Tea runtime to quit, exiting the program.
+
+### The View Method
+
+At last, it’s time to render our UI. Of all the methods, the view is the
+simplest. We look at the model in its current state and use it to return
+a `string`. That string is our UI!
+
+Because the view describes the entire UI of your application, you don’t have to
+worry about redrawing logic and stuff like that. Bubble Tea takes care of it
+for you.
+
+```go
+func (m model) View() string {
+    // The header
+    s := "What should we buy at the market?\n\n"
+
+    // Iterate over our choices
+    for i, choice := range m.choices {
+
+        // Is the cursor pointing at this choice?
+        cursor := " " // no cursor
+        if m.cursor == i {
+            cursor = ">" // cursor!
+        }
+
+        // Is this choice selected?
+        checked := " " // not selected
+        if _, ok := m.selected[i]; ok {
+            checked = "x" // selected!
+        }
+
+        // Render the row
+        s += fmt.Sprintf("%s [%s] %s\n", cursor, checked, choice)
+    }
+
+    // The footer
+    s += "\nPress q to quit.\n"
+
+    // Send the UI for rendering
+    return s
+}
+```
+
+### All Together Now
+
+The last step is to simply run our program. We pass our initial model to
+`tea.NewProgram` and let it rip:
+
+```go
+func main() {
+    p := tea.NewProgram(initialModel())
+    if _, err := p.Run(); err != nil {
+        fmt.Printf("Alas, there's been an error: %v", err)
+        os.Exit(1)
+    }
+}
+```
+
+## What’s Next?
+
+This tutorial covers the basics of building an interactive terminal UI, but
+in the real world you'll also need to perform I/O. To learn about that have a
+look at the [Command Tutorial][cmd]. It's pretty simple.
+
+There are also several [Bubble Tea examples][examples] available and, of course,
+there are [Go Docs][docs].
+
+[cmd]: https://github.com/charmbracelet/bubbletea/tree/main/tutorials/commands/
+[examples]: https://github.com/charmbracelet/bubbletea/tree/main/examples
+[docs]: https://pkg.go.dev/github.com/charmbracelet/bubbletea?tab=doc
+
+## Debugging
+
+### Debugging with Delve
+
+Since Bubble Tea apps assume control of stdin and stdout, you’ll need to run
+delve in headless mode and then connect to it:
+
+```bash
+# Start the debugger
+$ dlv debug --headless --api-version=2 --listen=127.0.0.1:43000 .
+API server listening at: 127.0.0.1:43000
+
+# Connect to it from another terminal
+$ dlv connect 127.0.0.1:43000
+```
+
+If you do not explicitly supply the `--listen` flag, the port used will vary
+per run, so passing this in makes the debugger easier to use from a script
+or your IDE of choice.
+
+Additionally, we pass in `--api-version=2` because delve defaults to version 1
+for backwards compatibility reasons. However, delve recommends using version 2
+for all new development and some clients may no longer work with version 1.
+For more information, see the [Delve documentation](https://github.com/go-delve/delve/tree/master/Documentation/api).
+
+### Logging Stuff
+
+You can’t really log to stdout with Bubble Tea because your TUI is busy
+occupying that! You can, however, log to a file by including something like
+the following prior to starting your Bubble Tea program:
+
+```go
+if len(os.Getenv("DEBUG")) > 0 {
+	f, err := tea.LogToFile("debug.log", "debug")
+	if err != nil {
+		fmt.Println("fatal:", err)
+		os.Exit(1)
+	}
+	defer f.Close()
+}
+```
+
+To see what’s being logged in real time, run `tail -f debug.log` while you run
+your program in another window.

+</p>
+
+A simple, powerful—and at times magical—package for detecting terminal color
+profiles and performing color (and CSI) degradation.
+
+## Detecting the terminal’s color profile
+
+Detecting the terminal’s color profile is easy.
+
+```go
+import "github.com/charmbracelet/colorprofile"
+
+// Detect the color profile. If you’re planning on writing to stderr you'd want
+// to use os.Stderr instead.
+p := colorprofile.Detect(os.Stdout, os.Environ())
+
+// Comment on the profile.
+fmt.Printf("You know, your colors are quite %s.", func() string {
+    switch p {
+    case colorprofile.TrueColor:
+        return "fancy"
+    case colorprofile.ANSI256:
+        return "1990s fancy"
+    case colorprofile.ANSI:
+        return "normcore"
+    case colorprofile.Ascii:
+        return "ancient"
+    case colorprofile.NoTTY:
+        return "naughty!"
+    }
+    return "...IDK" // this should never happen
+}())
+```
+
+## Downsampling colors
+
+When necessary, colors can be downsampled to a given profile, or manually
+downsampled to a specific profile.
+
+```go
+p := colorprofile.Detect(os.Stdout, os.Environ())
+c := color.RGBA{0x6b, 0x50, 0xff, 0xff} // #6b50ff
+
+// Downsample to the detected profile, when necessary.
+convertedColor := p.Convert(c)
+
+// Or manually convert to a given profile.
+ansi256Color := colorprofile.ANSI256.Convert(c)
+ansiColor := colorprofile.ANSI.Convert(c)
+noColor := colorprofile.Ascii.Convert(c)
+noANSI := colorprofile.NoTTY.Convert(c)
+```
+
+## Automatic downsampling with a Writer
+
+You can also magically downsample colors in ANSI output, when necessary. If
+output is not a TTY ANSI will be dropped entirely.
+
+```go
+myFancyANSI := "\x1b[38;2;107;80;255mCute \x1b[1;3mpuppy!!\x1b[m"
+
+// Automatically downsample for the terminal at stdout.
+w := colorprofile.NewWriter(os.Stdout, os.Environ())
+fmt.Fprintf(w, myFancyANSI)
+
+// Downsample to 4-bit ANSI.
+w.Profile = colorprofile.ANSI
+fmt.Fprintf(w, myFancyANSI)
+
+// Ascii-fy, no colors.
+w.Profile = colorprofile.Ascii
+fmt.Fprintf(w, myFancyANSI)
+
+// Strip ANSI altogether.
+w.Profile = colorprofile.NoTTY
+fmt.Fprintf(w, myFancyANSI) // not as fancy
+```

+		case 90, 91, 92, 93, 94, 95, 96, 97: // 8-bit bright foreground color
+			if w.Profile < ANSI {
+				continue
+			}
+			style = style.ForegroundColor(
+				w.Profile.Convert(ansi.BasicColor(param - 90 + 8))) //nolint:gosec
+		case 100, 101, 102, 103, 104, 105, 106, 107: // 8-bit bright background color
+			if w.Profile < ANSI {
+				continue
+			}
+			style = style.BackgroundColor(
+				w.Profile.Convert(ansi.BasicColor(param - 100 + 8))) //nolint:gosec
+		default:
+			// If this is not a color attribute, just append it to the style.
+			style = append(style, strconv.Itoa(param))
+		}
+	}
+
+	_, _ = buf.WriteString(style.String())

+
+Style definitions for nice terminal layouts. Built with TUIs in mind.
+
+![Lip Gloss example](https://github.com/user-attachments/assets/7950b1c1-e0e3-427e-8e7d-6f7f6ad17ca7)
+
+Lip Gloss takes an expressive, declarative approach to terminal rendering.
+Users familiar with CSS will feel at home with Lip Gloss.
+
+```go
+
+import "github.com/charmbracelet/lipgloss"
+
+var style = lipgloss.NewStyle().
+    Bold(true).
+    Foreground(lipgloss.Color("#FAFAFA")).
+    Background(lipgloss.Color("#7D56F4")).
+    PaddingTop(2).
+    PaddingLeft(4).
+    Width(22)
+
+fmt.Println(style.Render("Hello, kitty"))
+```
+
+## Colors
+
+Lip Gloss supports the following color profiles:
+
+### ANSI 16 colors (4-bit)
+
+```go
+lipgloss.Color("5")  // magenta
+lipgloss.Color("9")  // red
+lipgloss.Color("12") // light blue
+```
+
+### ANSI 256 Colors (8-bit)
+
+```go
+lipgloss.Color("86")  // aqua
+lipgloss.Color("201") // hot pink
+lipgloss.Color("202") // orange
+```
+
+### True Color (16,777,216 colors; 24-bit)
+
+```go
+lipgloss.Color("#0000FF") // good ol' 100% blue
+lipgloss.Color("#04B575") // a green
+lipgloss.Color("#3C3C3C") // a dark gray
+```
+
+...as well as a 1-bit ASCII profile, which is black and white only.
+
+The terminal's color profile will be automatically detected, and colors outside
+the gamut of the current palette will be automatically coerced to their closest
+available value.
+
+### Adaptive Colors
+
+You can also specify color options for light and dark backgrounds:
+
+```go
+lipgloss.AdaptiveColor{Light: "236", Dark: "248"}
+```
+
+The terminal's background color will automatically be detected and the
+appropriate color will be chosen at runtime.
+
+### Complete Colors
+
+CompleteColor specifies exact values for True Color, ANSI256, and ANSI color
+profiles.
+
+```go
+lipgloss.CompleteColor{TrueColor: "#0000FF", ANSI256: "86", ANSI: "5"}
+```
+
+Automatic color degradation will not be performed in this case and it will be
+based on the color specified.
+
+### Complete Adaptive Colors
+
+You can use `CompleteColor` with `AdaptiveColor` to specify the exact values for
+light and dark backgrounds without automatic color degradation.
+
+```go
+lipgloss.CompleteAdaptiveColor{
+    Light: CompleteColor{TrueColor: "#d7ffae", ANSI256: "193", ANSI: "11"},
+    Dark:  CompleteColor{TrueColor: "#d75fee", ANSI256: "163", ANSI: "5"},
+}
+```
+
+## Inline Formatting
+
+Lip Gloss supports the usual ANSI text formatting options:
+
+```go
+var style = lipgloss.NewStyle().
+    Bold(true).
+    Italic(true).
+    Faint(true).
+    Blink(true).
+    Strikethrough(true).
+    Underline(true).
+    Reverse(true)
+```
+
+## Block-Level Formatting
+
+Lip Gloss also supports rules for block-level formatting:
+
+```go
+// Padding
+var style = lipgloss.NewStyle().
+    PaddingTop(2).
+    PaddingRight(4).
+    PaddingBottom(2).
+    PaddingLeft(4)
+
+// Margins
+var style = lipgloss.NewStyle().
+    MarginTop(2).
+    MarginRight(4).
+    MarginBottom(2).
+    MarginLeft(4)
+```
+
+There is also shorthand syntax for margins and padding, which follows the same
+format as CSS:
+
+```go
+// 2 cells on all sides
+lipgloss.NewStyle().Padding(2)
+
+// 2 cells on the top and bottom, 4 cells on the left and right
+lipgloss.NewStyle().Margin(2, 4)
+
+// 1 cell on the top, 4 cells on the sides, 2 cells on the bottom
+lipgloss.NewStyle().Padding(1, 4, 2)
+
+// Clockwise, starting from the top: 2 cells on the top, 4 on the right, 3 on
+// the bottom, and 1 on the left
+lipgloss.NewStyle().Margin(2, 4, 3, 1)
+```
+
+## Aligning Text
+
+You can align paragraphs of text to the left, right, or center.
+
+```go
+var style = lipgloss.NewStyle().
+    Width(24).
+    Align(lipgloss.Left).  // align it left
+    Align(lipgloss.Right). // no wait, align it right
+    Align(lipgloss.Center) // just kidding, align it in the center
+```
+
+## Width and Height
+
+Setting a minimum width and height is simple and straightforward.
+
+```go
+var style = lipgloss.NewStyle().
+    SetString("What’s for lunch?").
+    Width(24).
+    Height(32).
+    Foreground(lipgloss.Color("63"))
+```
+
+## Borders
+
+Adding borders is easy:
+
+```go
+// Add a purple, rectangular border
+var style = lipgloss.NewStyle().
+    BorderStyle(lipgloss.NormalBorder()).
+    BorderForeground(lipgloss.Color("63"))
+
+// Set a rounded, yellow-on-purple border to the top and left
+var anotherStyle = lipgloss.NewStyle().
+    BorderStyle(lipgloss.RoundedBorder()).
+    BorderForeground(lipgloss.Color("228")).
+    BorderBackground(lipgloss.Color("63")).
+    BorderTop(true).
+    BorderLeft(true)
+
+// Make your own border
+var myCuteBorder = lipgloss.Border{
+    Top:         "._.:*:",
+    Bottom:      "._.:*:",
+    Left:        "|*",
+    Right:       "|*",
+    TopLeft:     "*",
+    TopRight:    "*",
+    BottomLeft:  "*",
+    BottomRight: "*",
+}
+```
+
+There are also shorthand functions for defining borders, which follow a similar
+pattern to the margin and padding shorthand functions.
+
+```go
+// Add a thick border to the top and bottom
+lipgloss.NewStyle().
+    Border(lipgloss.ThickBorder(), true, false)
+
+// Add a double border to the top and left sides. Rules are set clockwise
+// from top.
+lipgloss.NewStyle().
+    Border(lipgloss.DoubleBorder(), true, false, false, true)
+```
+
+For more on borders see [the docs][docs].
+
+## Copying Styles
+
+Just use assignment:
+
+```go
+style := lipgloss.NewStyle().Foreground(lipgloss.Color("219"))
+
+copiedStyle := style // this is a true copy
+
+wildStyle := style.Blink(true) // this is also true copy, with blink added
+
+```
+
+Since `Style` data structures contains only primitive types, assigning a style
+to another effectively creates a new copy of the style without mutating the
+original.
+
+## Inheritance
+
+Styles can inherit rules from other styles. When inheriting, only unset rules
+on the receiver are inherited.
+
+```go
+var styleA = lipgloss.NewStyle().
+    Foreground(lipgloss.Color("229")).
+    Background(lipgloss.Color("63"))
+
+// Only the background color will be inherited here, because the foreground
+// color will have been already set:
+var styleB = lipgloss.NewStyle().
+    Foreground(lipgloss.Color("201")).
+    Inherit(styleA)
+```
+
+## Unsetting Rules
+
+All rules can be unset:
+
+```go
+var style = lipgloss.NewStyle().
+    Bold(true).                        // make it bold
+    UnsetBold().                       // jk don't make it bold
+    Background(lipgloss.Color("227")). // yellow background
+    UnsetBackground()                  // never mind
+```
+
+When a rule is unset, it won't be inherited or copied.
+
+## Enforcing Rules
+
+Sometimes, such as when developing a component, you want to make sure style
+definitions respect their intended purpose in the UI. This is where `Inline`
+and `MaxWidth`, and `MaxHeight` come in:
+
+```go
+// Force rendering onto a single line, ignoring margins, padding, and borders.
+someStyle.Inline(true).Render("yadda yadda")
+
+// Also limit rendering to five cells
+someStyle.Inline(true).MaxWidth(5).Render("yadda yadda")
+
+// Limit rendering to a 5x5 cell block
+someStyle.MaxWidth(5).MaxHeight(5).Render("yadda yadda")
+```
+
+## Tabs
+
+The tab character (`\t`) is rendered differently in different terminals (often
+as 8 spaces, sometimes 4). Because of this inconsistency, Lip Gloss converts
+tabs to 4 spaces at render time. This behavior can be changed on a per-style
+basis, however:
+
+```go
+style := lipgloss.NewStyle() // tabs will render as 4 spaces, the default
+style = style.TabWidth(2)    // render tabs as 2 spaces
+style = style.TabWidth(0)    // remove tabs entirely
+style = style.TabWidth(lipgloss.NoTabConversion) // leave tabs intact
+```
+
+## Rendering
+
+Generally, you just call the `Render(string...)` method on a `lipgloss.Style`:
+
+```go
+style := lipgloss.NewStyle().Bold(true).SetString("Hello,")
+fmt.Println(style.Render("kitty.")) // Hello, kitty.
+fmt.Println(style.Render("puppy.")) // Hello, puppy.
+```
+
+But you could also use the Stringer interface:
+
+```go
+var style = lipgloss.NewStyle().SetString("你好，猫咪。").Bold(true)
+fmt.Println(style) // 你好，猫咪。
+```
+
+### Custom Renderers
+
+Custom renderers allow you to render to a specific outputs. This is
+particularly important when you want to render to different outputs and
+correctly detect the color profile and dark background status for each, such as
+in a server-client situation.
+
+```go
+func myLittleHandler(sess ssh.Session) {
+    // Create a renderer for the client.
+    renderer := lipgloss.NewRenderer(sess)
+
+    // Create a new style on the renderer.
+    style := renderer.NewStyle().Background(lipgloss.AdaptiveColor{Light: "63", Dark: "228"})
+
+    // Render. The color profile and dark background state will be correctly detected.
+    io.WriteString(sess, style.Render("Heyyyyyyy"))
+}
+```
+
+For an example on using a custom renderer over SSH with [Wish][wish] see the
+[SSH example][ssh-example].
+
+## Utilities
+
+In addition to pure styling, Lip Gloss also ships with some utilities to help
+assemble your layouts.
+
+### Joining Paragraphs
+
+Horizontally and vertically joining paragraphs is a cinch.
+
+```go
+// Horizontally join three paragraphs along their bottom edges
+lipgloss.JoinHorizontal(lipgloss.Bottom, paragraphA, paragraphB, paragraphC)
+
+// Vertically join two paragraphs along their center axes
+lipgloss.JoinVertical(lipgloss.Center, paragraphA, paragraphB)
+
+// Horizontally join three paragraphs, with the shorter ones aligning 20%
+// from the top of the tallest
+lipgloss.JoinHorizontal(0.2, paragraphA, paragraphB, paragraphC)
+```
+
+### Measuring Width and Height
+
+Sometimes you’ll want to know the width and height of text blocks when building
+your layouts.
+
+```go
+// Render a block of text.
+var style = lipgloss.NewStyle().
+    Width(40).
+    Padding(2)
+var block string = style.Render(someLongString)
+
+// Get the actual, physical dimensions of the text block.
+width := lipgloss.Width(block)
+height := lipgloss.Height(block)
+
+// Here's a shorthand function.
+w, h := lipgloss.Size(block)
+```
+
+### Placing Text in Whitespace
+
+Sometimes you’ll simply want to place a block of text in whitespace.
+
+```go
+// Center a paragraph horizontally in a space 80 cells wide. The height of
+// the block returned will be as tall as the input paragraph.
+block := lipgloss.PlaceHorizontal(80, lipgloss.Center, fancyStyledParagraph)
+
+// Place a paragraph at the bottom of a space 30 cells tall. The width of
+// the text block returned will be as wide as the input paragraph.
+block := lipgloss.PlaceVertical(30, lipgloss.Bottom, fancyStyledParagraph)
+
+// Place a paragraph in the bottom right corner of a 30x80 cell space.
+block := lipgloss.Place(30, 80, lipgloss.Right, lipgloss.Bottom, fancyStyledParagraph)
+```
+
+You can also style the whitespace. For details, see [the docs][docs].
+
+## Rendering Tables
+
+Lip Gloss ships with a table rendering sub-package.
+
+```go
+import "github.com/charmbracelet/lipgloss/table"
+```
+
+Define some rows of data.
+
+```go
+rows := [][]string{
+    {"Chinese", "您好", "你好"},
+    {"Japanese", "こんにちは", "やあ"},
+    {"Arabic", "أهلين", "أهلا"},
+    {"Russian", "Здравствуйте", "Привет"},
+    {"Spanish", "Hola", "¿Qué tal?"},
+}
+```
+
+Use the table package to style and render the table.
+
+```go
+var (
+    purple    = lipgloss.Color("99")
+    gray      = lipgloss.Color("245")
+    lightGray = lipgloss.Color("241")
+
+    headerStyle  = lipgloss.NewStyle().Foreground(purple).Bold(true).Align(lipgloss.Center)
+    cellStyle    = lipgloss.NewStyle().Padding(0, 1).Width(14)
+    oddRowStyle  = cellStyle.Foreground(gray)
+    evenRowStyle = cellStyle.Foreground(lightGray)
+)
+
+t := table.New().
+    Border(lipgloss.NormalBorder()).
+    BorderStyle(lipgloss.NewStyle().Foreground(purple)).
+    StyleFunc(func(row, col int) lipgloss.Style {
+        switch {
+        case row == table.HeaderRow:
+            return headerStyle
+        case row%2 == 0:
+            return evenRowStyle
+        default:
+            return oddRowStyle
+        }
+    }).
+    Headers("LANGUAGE", "FORMAL", "INFORMAL").
+    Rows(rows...)
+
+// You can also add tables row-by-row
+t.Row("English", "You look absolutely fabulous.", "How's it going?")
+```
+
+Print the table.
+
+```go
+fmt.Println(t)
+```
+
+![Table Example](https://github.com/charmbracelet/lipgloss/assets/42545625/6e4b70c4-f494-45da-a467-bdd27df30d5d)
+
+> [!WARNING]
+> Table `Rows` need to be declared before `Offset` otherwise it does nothing.
+
+### Table Borders
+
+There are helpers to generate tables in markdown or ASCII style:
+
+#### Markdown Table
+
+```go
+table.New().Border(lipgloss.MarkdownBorder()).BorderTop(false).BorderBottom(false)
+```
+
+```
+| LANGUAGE |    FORMAL    | INFORMAL  |
+|----------|--------------|-----------|
+| Chinese  | Nǐn hǎo      | Nǐ hǎo    |
+| French   | Bonjour      | Salut     |
+| Russian  | Zdravstvuyte | Privet    |
+| Spanish  | Hola         | ¿Qué tal? |
+```
+
+#### ASCII Table
+
+```go
+table.New().Border(lipgloss.ASCIIBorder())
+```
+
+```
++----------+--------------+-----------+
+| LANGUAGE |    FORMAL    | INFORMAL  |
++----------+--------------+-----------+
+| Chinese  | Nǐn hǎo      | Nǐ hǎo    |
+| French   | Bonjour      | Salut     |
+| Russian  | Zdravstvuyte | Privet    |
+| Spanish  | Hola         | ¿Qué tal? |
++----------+--------------+-----------+
+```
+
+For more on tables see [the docs](https://pkg.go.dev/github.com/charmbracelet/lipgloss?tab=doc) and [examples](https://github.com/charmbracelet/lipgloss/tree/master/examples/table).
+
+## Rendering Lists
+
+Lip Gloss ships with a list rendering sub-package.
+
+```go
+import "github.com/charmbracelet/lipgloss/list"
+```
+
+Define a new list.
+
+```go
+l := list.New("A", "B", "C")
+```
+
+Print the list.
+
+```go
+fmt.Println(l)
+
+// • A
+// • B
+// • C
+```
+
+Lists have the ability to nest.
+
+```go
+l := list.New(
+    "A", list.New("Artichoke"),
+    "B", list.New("Baking Flour", "Bananas", "Barley", "Bean Sprouts"),
+    "C", list.New("Cashew Apple", "Cashews", "Coconut Milk", "Curry Paste", "Currywurst"),
+    "D", list.New("Dill", "Dragonfruit", "Dried Shrimp"),
+    "E", list.New("Eggs"),
+    "F", list.New("Fish Cake", "Furikake"),
+    "J", list.New("Jicama"),
+    "K", list.New("Kohlrabi"),
+    "L", list.New("Leeks", "Lentils", "Licorice Root"),
+)
+```
+
+Print the list.
+
+```go
+fmt.Println(l)
+```
+
+<p align="center">
+<img width="600" alt="image" src="https://github.com/charmbracelet/lipgloss/assets/42545625/0dc9f440-0748-4151-a3b0-7dcf29dfcdb0">
+</p>
+
+Lists can be customized via their enumeration function as well as using
+`lipgloss.Style`s.
+
+```go
+enumeratorStyle := lipgloss.NewStyle().Foreground(lipgloss.Color("99")).MarginRight(1)
+itemStyle := lipgloss.NewStyle().Foreground(lipgloss.Color("212")).MarginRight(1)
+
+l := list.New(
+    "Glossier",
+    "Claire’s Boutique",
+    "Nyx",
+    "Mac",
+    "Milk",
+    ).
+    Enumerator(list.Roman).
+    EnumeratorStyle(enumeratorStyle).
+    ItemStyle(itemStyle)
+```
+

+</p>
+
+In addition to the predefined enumerators (`Arabic`, `Alphabet`, `Roman`, `Bullet`, `Tree`),
+you may also define your own custom enumerator:
+
+```go
+l := list.New("Duck", "Duck", "Duck", "Duck", "Goose", "Duck", "Duck")
+
+func DuckDuckGooseEnumerator(l list.Items, i int) string {
+    if l.At(i).Value() == "Goose" {
+        return "Honk →"
+    }
+    return ""
+}
+
+l = l.Enumerator(DuckDuckGooseEnumerator)
+```
+
+Print the list:
+
+<p align="center">
+<img width="600" alt="image" src="https://github.com/charmbracelet/lipgloss/assets/42545625/157aaf30-140d-4948-9bb4-dfba46e5b87e">
+</p>
+
+If you need, you can also build lists incrementally:
+
+```go
+l := list.New()
+
+for i := 0; i < repeat; i++ {
+    l.Item("Lip Gloss")
+}
+```
+
+## Rendering Trees
+
+Lip Gloss ships with a tree rendering sub-package.
+
+```go
+import "github.com/charmbracelet/lipgloss/tree"
+```
+
+Define a new tree.
+
+```go
+t := tree.Root(".").
+    Child("A", "B", "C")
+```
+
+Print the tree.
+
+```go
+fmt.Println(t)
+
+// .
+// ├── A
+// ├── B
+// └── C
+```
+
+Trees have the ability to nest.
+
+```go
+t := tree.Root(".").
+    Child("macOS").
+    Child(
+        tree.New().
+            Root("Linux").
+            Child("NixOS").
+            Child("Arch Linux (btw)").
+            Child("Void Linux"),
+        ).
+    Child(
+        tree.New().
+            Root("BSD").
+            Child("FreeBSD").
+            Child("OpenBSD"),
+    )
+```
+
+Print the tree.
+
+```go
+fmt.Println(t)
+```
+
+<p align="center">
+<img width="663" alt="Tree Example (simple)" src="https://github.com/user-attachments/assets/5ef14eb8-a5d4-4f94-8834-e15d1e714f89">
+</p>
+
+Trees can be customized via their enumeration function as well as using
+`lipgloss.Style`s.
+
+```go
+enumeratorStyle := lipgloss.NewStyle().Foreground(lipgloss.Color("63")).MarginRight(1)
+rootStyle := lipgloss.NewStyle().Foreground(lipgloss.Color("35"))
+itemStyle := lipgloss.NewStyle().Foreground(lipgloss.Color("212"))
+
+t := tree.
+    Root("⁜ Makeup").
+    Child(
+        "Glossier",
+        "Fenty Beauty",
+        tree.New().Child(
+            "Gloss Bomb Universal Lip Luminizer",
+            "Hot Cheeks Velour Blushlighter",
+        ),
+        "Nyx",
+        "Mac",
+        "Milk",
+    ).
+    Enumerator(tree.RoundedEnumerator).
+    EnumeratorStyle(enumeratorStyle).
+    RootStyle(rootStyle).
+    ItemStyle(itemStyle)
+```
+
+Print the tree.
+
+<p align="center">
+<img width="663" alt="Tree Example (makeup)" src="https://github.com/user-attachments/assets/06d12d87-744a-4c89-bd98-45de9094a97e">
+</p>
+
+The predefined enumerators for trees are `DefaultEnumerator` and `RoundedEnumerator`.
+
+If you need, you can also build trees incrementally:
+
+```go
+t := tree.New()
+
+for i := 0; i < repeat; i++ {
+    t.Child("Lip Gloss")
+}
+```

+## FAQ
+
+<details>
+<summary>
+Why are things misaligning? Why are borders at the wrong widths?
+</summary>
+<p>This is most likely due to your locale and encoding, particularly with
+regard to Chinese, Japanese, and Korean (for example, <code>zh_CN.UTF-8</code>
+or <code>ja_JP.UTF-8</code>). The most direct way to fix this is to set
+<code>RUNEWIDTH_EASTASIAN=0</code> in your environment.</p>
+
+<p>For details see <a href="https://github.com/charmbracelet/lipgloss/issues/40">https://github.com/charmbracelet/lipgloss/issues/40.</a></p>
+</details>
+
+<details>
+<summary>
+Why isn't Lip Gloss displaying colors?
+</summary>
+<p>Lip Gloss automatically degrades colors to the best available option in the
+given terminal, and if output's not a TTY it will remove color output entirely.
+This is common when running tests, CI, or when piping output elsewhere.</p>
+
+<p>If necessary, you can force a color profile in your tests with
+<a href="https://pkg.go.dev/github.com/charmbracelet/lipgloss#SetColorProfile"><code>SetColorProfile</code></a>.</p>
+
+```go
+import (
+    "github.com/charmbracelet/lipgloss"
+    "github.com/muesli/termenv"
+)
+
+lipgloss.SetColorProfile(termenv.TrueColor)
+```
+
+_Note:_ this option limits the flexibility of your application and can cause
+ANSI escape codes to be output in cases where that might not be desired. Take
+careful note of your use case and environment before choosing to force a color
+profile.
+
+</details>
+
+## What about [Bubble Tea][tea]?
+
+Lip Gloss doesn’t replace Bubble Tea. Rather, it is an excellent Bubble Tea
+companion. It was designed to make assembling terminal user interface views as
+simple and fun as possible so that you can focus on building your application
+instead of concerning yourself with low-level layout details.
+
+In simple terms, you can use Lip Gloss to help build your Bubble Tea views.
+
+[tea]: https://github.com/charmbracelet/tea
+
+## Under the Hood
+
+Lip Gloss is built on the excellent [Termenv][termenv] and [Reflow][reflow]
+libraries which deal with color and ANSI-aware text operations, respectively.
+For many use cases Termenv and Reflow will be sufficient for your needs.

+## Rendering Markdown
+
+For a more document-centric rendering solution with support for things like
+lists, tables, and syntax-highlighted code have a look at [Glamour][glamour],
+the stylesheet-based Markdown renderer.
