-`cheat` may be integrated with [fzf][]. See [fzf.bash][bash] for instructions.
-(Support for other shells will be added in future releases.)
+Shell autocompletion is currently available for `bash`, `fish`, and `zsh`. Copy
+the relevant [completion script][completions] into the appropriate directory on
+your filesystem to enable autocompletion. (This directory will vary depending
+on operating system and shell specifics.)
 
+Additionally, `cheat` supports enhanced autocompletion via integration with
+[fzf][]. To enable `fzf` integration:
+
+1. Ensure that `fzf` is available on your `$PATH`
+2. Set an envvar: `export CHEAT_USE_FZF=true`

+FILES
+=====
+
+Configuration
+-------------
+**cheat** is configured via a YAML file that is conventionally named
+_conf.yaml_.  **cheat** will search for _conf.yaml_ in varying locations,
+depending upon your platform:
+
+### Linux, OSX, and other Unixes ###
+
+1. **CHEAT_CONFIG_PATH**
+2. **XDG_CONFIG_HOME**/cheat/conf.yaml
+3. **$HOME**/.config/cheat/conf.yml
+4. **$HOME**/.cheat/conf.yml
+
+### Windows ###
+
+1. **CHEAT_CONFIG_PATH**
+2. **APPDATA**/cheat/conf.yml
+3. **PROGRAMDATA**/cheat/conf.yml
+
+**cheat** will search in the order specified above. The first _conf.yaml_
+encountered will be respected.
+
+If **cheat** cannot locate a config file, it will ask if you'd like to generate
+one automatically. Alternatively, you may also generate a config file manually
+by running **cheat --init** and saving its output to the appropriate location
+for your platform.
+
+
+Cheatpaths
+----------
+**cheat** reads its cheatsheets from "cheatpaths", which are the directories in
+which cheatsheets are stored. Cheatpaths may be configured in _conf.yaml_, and
+viewed via **cheat -d**.
+
+For detailed instructions on how to configure cheatpaths, please refer to the
+comments in conf.yml.
+
+
+Autocompletion
+--------------
+Autocompletion scripts for **bash**, **zsh**, and **fish** are available for
+download:
+
+- <https://github.com/cheat/cheat/blob/master/scripts/cheat.bash>
+- <https://github.com/cheat/cheat/blob/master/scripts/cheat.fish>
+- <https://github.com/cheat/cheat/blob/master/scripts/cheat.zsh>
+
+The **bash** and **zsh** scripts provide optional integration with **fzf**, if
+the latter is available on your **PATH**.
+
+The installation process will vary per system and shell configuration, and thus
+will not be discussed here.
+
+
+ENVIRONMENT
+===========
+
+**CHEAT_CONFIG_PATH**
+
+: The path at which the config file is available. If **CHEAT_CONFIG_PATH** is
+set, all other config paths will be ignored.
+
+**CHEAT_USE_FZF**
+
+: If set, autocompletion scripts will attempt to integrate with **fzf**.

+## RE2 compatibility mode
+The default behavior of `regexp2` is to match the .NET regexp engine, however the `RE2` option is provided to change the parsing to increase compatibility with RE2.  Using the `RE2` option when compiling a regexp will not take away any features, but will change the following behaviors:
+* add support for named ascii character classes (e.g. `[[:foo:]]`)
+* add support for python-style capture groups (e.g. `(P<name>re)`)
+
+```go
+re := regexp2.MustCompile(`Your RE2-compatible pattern`, regexp2.RE2)
+if isMatch, _ := re.MatchString(`Something to match`); isMatch {
+    //do something
+}
+```
+
+This feature is a work in progress and I'm open to ideas for more things to put here (maybe more relaxed character escaping rules?).
