 ## Usage  
 ### Master  
+Copy `overwrought_master.py` and the matching config file to your `.minecraft/` folder. Edit the config file appropriately.  
 `$ python3 overwrought_master.py action [options] [target]`  
 __actions__  
 * `add` Add a new mod to the modpack. `target` must be a url to a curseforge mod project page. By default, it will prioritize release phases as Release, Beta and then Alpha. `--phase` can alter this. Will always grab the latest version of whichever phase it targets.  
@@ -19,5 +20,12 @@ __actions__
 * `update` Update a specific mod in the modpack. `target` must be the url associated with the mod. By default, it will prioritize the release phase previously added. `--phase` can alter this. Will only update if the targeted mod is more recent than the one previously downloaded.  
 * `update_all` Update every mod in the modpack. No `target` needed. Will prioritize release phases similar to `update`, however `--phase` will will not affect it.  
 * `summary` Generate a summary page as html. Summary page displays a list of all mods in the modpack and a change log that is updated as changes are made to the modpack.

 ### Server  
 `gunicorn -b localhost:5000 -e SCRIPT_NAME=/overwrought overwrought_server:app`  
+Use `overwrought_server.py hash` to generate an Argon2 hash of your password. Update `config_server.py` appropriately.  
+
+### Slave  
+Copy `overwrought_slave.py` and the matching config file to your `.minecraft/` folder. Edit the config file appropriately.  
+Use `overwrought_slave.py sync` to synchronize the `mods/` folder with the remote server.  
+By default, old versions of mods (and any other non-modpack related file found in the `mods/` folder) will be moved to `mods_old/`. `--delete` may be used to delete these files instead eg. `overwrought_slave.py sync --delete`.
