 transparently copy that sheet to a writeable directory before opening it for
 editing.
 
+### Directory-scoped Cheatpaths ###
+At times, it can be useful to closely associate cheatsheets with a directory on
+your filesystem. `cheat` facilitates this by searching for a `.cheat` folder in
+the current working directory. If found, the `.cheat` directory will
+(temporarily) be added to the cheatpaths.

 Advanced Usage
 --------------
-`cheat` may be integrated with [fzf][]. See [fzf.bash][bash] for instructions.
+Shell autocompletion is currently available for the `bash` and `fish` shells.
-(Support for other shells will be added in future releases.)
+Copy the relevant [completion script][completion-scripts] 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][]. (This feature is currently available on bash only.) To enable `fzf`
+integration:
+
+1. Ensure that `fzf` is available on your `$PATH`
+2. Set an envvar: `export CHEAT_USE_FZF=true`

-Colorable writer for windows.
-
-For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
-This package is possible to handle escape sequence for ansi color on windows.

-## Too Bad!

-
-
-## So Good!
-
-![](https://raw.githubusercontent.com/mattn/go-colorable/gh-pages/good.png)
-
-## Usage
-
-```go
-logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
-logrus.SetOutput(colorable.NewColorableStdout())
-
-logrus.Info("succeeded")
-logrus.Warn("not correct")
-logrus.Error("something error")
-logrus.Fatal("panic")
-```
-
-You can compile above code on non-windows OSs.

-# ansi
-
-Package ansi is a small, fast library to create ANSI colored strings and codes.
-
-## Install
-
-Get it
-
-```sh
-go get -u github.com/mgutz/ansi
-```
-
-## Example
-
-```go
-import "github.com/mgutz/ansi"
-
-// colorize a string, SLOW
-msg := ansi.Color("foo", "red+b:white")
-
-// create a FAST closure function to avoid computation of ANSI code
-phosphorize := ansi.ColorFunc("green+h:black")
-msg = phosphorize("Bring back the 80s!")
-msg2 := phospohorize("Look, I'm a CRT!")
-
-// cache escape codes and build strings manually
