 # Chromium pywal theme generator
 
-Generates a chromium theme by using colors generated by [pywal](https://github.com/dylanaraps/pywal)
+Generates [pywal](https://github.com/dylanaraps/pywal) theme for Chromium
 
 ![Screenshot](./Screenshots/screenshot.png)
 
+## Usage
+
+1. Run script `./generate-theme.sh`
+2. Open chromium
+3. Go to `chrome://extensions`
+4. Turn on "Developer Mode" in the top right corner
+5. Press "Load unpacked"
+6. Select "Pywal" (by default) in the same folder with the script
+7. ???
+8. PROFIT!
+
+However, you need to run this script and restart chromium each time you change pywal colors (or reload extension manually, since there is no way to do it automatically).
+So, make an alias or something like that.
+But you don't need to repeat the steps above, just run the script and that's it, chromium will update theme colors automatically. 😁
