plugins/pm2/README.md

+# pm2 plugin
+
+The plugin adds several aliases and completions for common [pm2](http://pm2.keymetrics.io/) commands.
+
+To use it, add `pm2` to the plugins array of your zshrc file:
+```
+plugins=(... pm2)
+```
+
+## Aliases
+
+| Alias  | Command              |
+|--------|----------------------|
+| p2s  | `pm2 start` |
+| p2o  | `pm2 stop` |
+| p2d | `pm2 delete` |
+| p2r   | `pm2 restart` |
+| p2i   | `pm2 list` |
