+### def
+This plugin is used to specify and run a default command in any directory of your choice
+
+To use it you can either run `def init` to create the default config file or create a `.def` file on a folder by folder basis
+
+## Configuration
+The default configuration file is stored in `$XDG_CONFIG_HOME/def/`. If `$XDG_CONFIG_HOME` is not set then it defaults to `$HOME/.config`
+
+The structure of the file is a folder with relative command for each line. The folders can be specified as regex. The ~ character is automatically expanded to the `$HOME` directory
+
+If you use a local `.def` file then it should only hold the command to be executed
+
+# Example
+```
+/home/vinter/frontend npm run
+^/home/vinter/projects/go go build
+~/stuff/git git pull
+```
+
+## Additional commands
+You can add a command for the current folder by using `def add [command]`.
+```
+def add npm run
+```
+
+You can remove any commands that match the current folder by using `def remove`. Please note that it **will also remove** any local `.def` files.
