 An app that makes updating FreeTube from nightly build artifacts more automated.
 
-Usage: 
-```
-FreeTubeUpdater.get_download_link(personal_access_token, os, format)
-```
-
-Supported parameters are as follows:    
-os: win, linux, mac   
-format:
-   - for win:
-     - setup, portable   
-  - for linux:
-     - portable, AppImage
-  - for mac:
-     - dmg
+There is a simple one-time setup for using this app: 
+- copy `config.sample.json` to `config.json` in `/rel/freetube_updater/config`
+- fill in the three values in file
+   - token is your GitHub personal access token. You can easily generate one in https://github.com/settings/tokens
+      - I know this is inconvenient, but it takes just a minute or two and it's necessary, because
+      GitHub doesn't allow downloading artifacts for non-logged users.
+   - os value accepts `win`, `linux` or `mac`
+   - format value depends on your `os` type
+      - `win` accepts `setup` or `portable`
+      - `linux` accepts `portable` or `AppImage`
+      - `mac` accepts `dmg`
+
+- finally, you can start `run` script file or use command `rel/freetube_updater/bin/freetube_updater start`
+from the app root directory which will give you a download link for newest release of FreeTube
