+## 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 "GeneratedTheme" in the same folder with the script
+7. ???
+8. PROFIT!
+
+However, you need to run this script each time you change pywal colors.
+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. 😁
