+# BASH tab completion for possible FAKE tasks
+
+## Prerequisites
+
+If you have tab completion for other commands (such as git parameters) then you can skip to [Install](#install-completion-for-fake)
+
+##### OSX
+```bash
+brew install bash-completion
+```
+Paste the following into ~/.bash_profile (create the file if it doesn't already exist)
+```bash
+if [ -f $(brew --prefix)/etc/bash_completion ]; then
+    . $(brew --prefix)/etc/bash_completion
+fi
+```
+
+## Install completion for FAKE
+```bash
+cd bash-completion
+./install.sh
+```
