 ## Getting started
 
-- Submodule this repo or download `pure.zsh`.  
+- Place this file somewhere in `$fpath` with the name `prompt_pure_setup`
-  *Submodule is recommended as it makes it easy to keep it up to date.*
+
-- In your `.zshrc` add any of the below options, then import pure `. path/to/pure.zsh`.
+For example:
+
+```
+$ sudo cp ./pure.zsh /usr/share/zsh/functions/Prompts/prompt_pure_setup
+```
+
+- Initialize the prompt system (if not so already):
+
+```sh
+# .zshrc
+autoload -U promptinit
+promptinit
+```
+
+- Choose this prompt:
+
+```sh
+# .zshrc
+prompt pure
