+## Features
+
+### Error checking with [Syntastic][syn]
+
+`rust.vim` automatically registers `rustc` as a syntax checker
+with [Syntastic][syn]. Check Syntastic's documentation for
+information on how to customize its behaviour.
+
+### Formatting with [rustfmt][rfmt]
+
+The `:RustFmt` command will format your code with
+[rustfmt][rfmt] if installed.
+
+Placing `let g:rustfmt_autosave = 1` in your `~/.vimrc` will
+enable automatic running of `:RustFmt` when you save a buffer.
+
+Do `:help :RustFmt` for further formatting help and customization
+options.
+
+### [Playpen][pp] integration
+
+*Note:* This feature requires [webapi-vim][wav] to be installed.
+
+The `:RustPlay` command will send the current selection, or if
+nothing is selected the current buffer, to the [Rust playpen][pp].
+
+If you set g:rust_clip_command RustPlay will copy the url to the clipboard.
+
+- Mac:
+
+        let g:rust_clip_command = 'pbcopy'
+
+- Linux:
+
+        let g:rust_clip_command = 'xclip -selection clipboard'

+automatically, but check their documentation if that is not the case.
