Under the hood it runs on Cordova with a CodeMirror 6 editor engine (exposed to plugins through an Ace-compatible API layer), and it ships as two editions from one codebase - free and Pro (unlocked via in-app purchase) - with a separate F-Droid build that strips out proprietary dependencies.

+## • Build Variants
+
+Acode is built from one codebase into several variants using the project's build script:
+
+```shell
+yarn build <free|paid> <p|prod|d|dev> [fdroid] <apk/bundle>
+```
+
+- `free` / `paid` - selects the build artifact: the `paid` build unlocks Pro features directly, with no purchase required for that package. An in-app purchase is a separate upgrade path that unlocks Pro inside the `free` package
+- `p`/`prod` or `d`/`dev` - production or development build
+- `fdroid` (optional flag) - produces the F-Droid-compatible build with proprietary dependencies removed; omit it for the regular Play Store build
+- `apk` or `bundle` - output format

 ## • Multi-language Support
 
 Enhance Acode's capabilities by adding new languages easily. Just create a file with the language code (e.g., en-us for English) in [`src/lang/`](https://github.com/Acode-Foundation/Acode/tree/main/src/lang) and include it in [`src/lib/lang.js`](https://github.com/Acode-Foundation/Acode/blob/main/src/lib/lang.js). Manage strings across languages effortlessly using utility commands:

+Every pull request touching `src/lang/*.json` is automatically checked by CI for structural consistency before it can be merged.
