+![Textadept](images/textadept.png)
+
+Textadept is a fast, minimalist, and ridiculously extensible cross-platform text
+editor for programmers. Written in a combination of C and [Lua][] and
+relentlessly optimized for speed and minimalism over the years, Textadept is an
+ideal editor for programmers who want endless extensibility options without
+sacrificing speed or succumbing to code bloat and featuritis.
+
+[Lua]: http://lua.org
+
+### Fast
+
+Textadept is _fast_. It starts up instantly and has a very responsive user
+interface (UI). Even though the editor is mostly written in Lua, Lua is one of
+the fastest scripting languages available. With [LuaJIT][], Textadept is faster
+than ever before, though using LuaJIT is overkill.
+
+[LuaJIT]: http://luajit.org
+
+### Minimalist
+
+Textadept is minimalist. Not only is this apparent in the UI, but the editor's C
+core was designed to never exceed 2000 lines of code and its Lua extension code
+is not supposed to go beyond 4000 lines. After 4 1/2 years of development,
+Textadept has fewer lines of code (~5000) than it did in its first release
+(~5600) and is vastly superior in every respect.
+
+### Ridiculously Extensible
+
+Textadept is ridiculously extensible. It was designed to be that way from the
+very beginning. The features came later. Most of Textadept is written in Lua,
+from syntax highlighting to opening and saving files to searching and replacing
+and more. Textadept gives you complete control over the entire application using
+Lua. You can do everything from moving the caret to changing menus and key
+commands on-the-fly to handling UI events. The possibilities are limitless.

+## Manual Notation
+
+* `~/` is denoted as the user's home directory. On Windows machines this is the
+  value of the `USERHOME` environment variable (typically `C:\Users\<username>\`
+  or `C:\Documents and Settings\<username>\`). On Linux and Mac OSX machines it
+  is the value of `HOME` (typically `/home/<username>/` and `/Users/<username>/`
+  respectively).
+* Any relative directory paths, i.e. paths that do not begin with `/` or `C:\`,
+  are relative to the location of Textadept.
+* Key combinations are not case-sensitive. `Ctrl+N` means the `N` key is pressed
+  with only the `Control` key being held down, not the `Shift` key.
+  `Ctrl+Shift+N` means the `N` key is pressed with both `Control` and `Shift`
+  keys being held down. The same notation is applicable to key chains:
+  `Ctrl+N, N` vs. `Ctrl+N, Shift+N`. In the first key chain, `Control` and `N`
+  are pressed followed by `N` with no modifiers. The second has `Control` and
+  `N` pressed followed by `Shift` and `N`.
+* When mentioning key commands, the Mac OSX equivalent will often be shown in
+  parenthesis. It may be tempting to assume that some Windows/Linux keys map to
+  Mac OSX's (e.g `Ctrl` to `⌘`), but this is not always the case. Please do not
+  view the key equivalents as translations of one another, but rather as
+  separate entities. This will minimize confusion.
