+# Original idea by DefV (Jan De Poorter)
+# Source: https://gist.github.com/pjaspers/368394#comment-1016
+#
+# Usage:
+#  - Set `$PROJECT_PATHS` in your ~/.zshrc
+#    e.g.: PROJECT_PATHS=(~/src ~/work)
+#  - In ZSH you now can open a project directory with the command: `pj my-project`
+#    the plugin will locate the `my-project` directory in one of the $PROJECT_PATHS
+#    Also tab completion is supported.
+#  - `pjo my-project` will open the directory in $EDITOR
+#
