 OpenWordle is a completely open source and lightweight wordle game with very minimal set of runtime dependencies
 
+## Features
+
+### 1. Scripting!
+
+You can use custom scripts to have fun with wordle!
+Script interface is exposed via `globalThis.ScriptInterface`.
+
+In order for scripts to run, the user must enable them by
+clicking on the "Enable scripts" button in the settings.
+
+After enabling scripts, all the game data would be available
+to the script. To expose cheaters, a warning text would appear near the header:
+"Scripts are allowed. The game may not be fair-played"
+
+To run the scripts, I recommend using [Tampermoney](https://www.tampermonkey.net).  
+Using the developer console is a fine option too.
+
+### 2. Extremely lightweight
+
+The whole app is \~ 100kb bundled, which is pretty impressive IMHO.
+
+The only 2 libraries are included via `await import`, and most of the
+weight is the bundled-in dictionary of ~7k words
+
+### 3. FOSS
+
+So far, I haven't found a wordle game that is FOSS. This is the one
+
+### 4. Customizable
+
+There is no scoped CSS which allows good space for customization.
