+# Themes
+
+Textadept's look and feel can be customized with themes. The themes that come
+with Textadept are `light` and `dark`'. By default the `light` theme is used. To
+change the theme, create a `~/.textadept/theme` file whose first line of text is
+the name of the theme you would like to use.

+
+Themes apply to all buffers. You cannot assign a theme to a particular file or
+filetype. You can change things like tab and indent settings per filetype
+however by creating a [language-specific module].
+
+[language-specific module]: 7_Modules.html#Buffer.Properties
+
+## Creating or Modifying Themes
+
+Each theme is a single folder on the filesystem composed of three files:
+`lexer.lua`, `buffer.lua`, and `view.lua`. It is recommended to put themes in
+your `~/.textadept/themes/` directory so they will not be overwritten when you
+update Textadept. Themes in that directory override any themes in Textadept's
+`themes/` directory. This means that if you have your own `light` theme, it will
+be loaded instead of the one that comes with Textadept.
+
+To use a theme not located in `~/.textadept/themes/` or Textadept's `themes/`
+directory, you need to specify an absolute path to the theme's folder in your
+`~/.textadept/theme` file.
+
+### Lexer
+
+Textadept uses lexers to assign names to buffer elements like comments, strings,
+and keywords. These elements are assigned styles composed of font and color
+information in the theme's `lexer.lua`. See the `Styling Tokens` section of the
+[lexer][] page for more information on how to create styles and colors.
+
+[lexer]: api/lexer.html
+
+### Buffer
+
+`buffer.lua` contains buffer-specific properties like indentation size and
+whether or not to use tabs. For example, to set the default tab size to 4 and
+use tabs:
+
+    buffer.tab_width = 4
+    buffer.use_tabs = true
+    buffer.indent = 4
+
+See the [LuaDoc][] for documentation on the properties.
+
+[LuaDoc]: api/buffer.html
+
+### View
+
+`view.lua` contains view-specific properties like caret and selection colors.
+See the [LuaDoc][] for documentation on the properties.
+
+[LuaDoc]: api/buffer.html
+
+## Testing Themes
+
+You can reload or switch between themes on the fly using `Ctrl+Shift+T` (⌘⇧T on
+Mac OSX), but be aware that the Scintilla views do not reset themselves, so any
+options set explicitly in the previous theme's `view.lua` file that are not set
+explicitly in the new theme will carry over. The switch feature is intended
+primarily for theme exploration and/or development and can be slow when many
+buffers or views are open.
+
+Any errors that occur in the theme are printed to `io.stderr`.
+
+## Theming the GUI
+
+There is no way to theme GUI controls like text fields and buttons from within
+Textadept. Instead, use [GTK Resource files][]. The `GtkWindow` name is
+`textadept`. For example, styling all text fields with a
+`"textadept-entry-style"` would be done like this:
+
+    widget "textadept*GtkEntry*" style "textadept-entry-style"
+

+
+## Getting Themes
+
+For now, user-created themes are obtained from the [wiki][]. The classic `dark`,
+`light`, and `scite` themes prior to version 4.3 have been moved there.
