+## Usage
+
+When you execute a command alias finder will look at your defined aliases and suggest shorter aliases you could have used, for example:
+
+Running the un-aliased `git status` command:
+```sh
+╭─tim@fox ~/repo/gitopolis ‹main› 
+╰─$ git status
+
+gst='git status'         # <=== shorter suggestion from alias-finder
+
+On branch main
+Your branch is up-to-date with 'origin/main'.
+nothing to commit, working tree clean
+```
+
+Running a shorter `git st` alias from `.gitconfig` that it suggested :
+```sh
+╭─tim@fox ~/repo/gitopolis ‹main› 
+╰─$ git st
+gs='git st'         # <=== shorter suggestion from alias-finder
+## main...origin/main
+```
+
+Running the shortest `gs` shell alias that it found:
+```sh
+╭─tim@fox ~/repo/gitopolis ‹main› 
+╰─$ gs
+         # <=== no suggestions alias-finder because this is the shortest
+## main...origin/main
+```
