 # Polylang Build Scripts
 
-These are the scripts needed to build Polylang. They are meant to be use as **dependencies** of both [Polylang](https://github.com/polylang/polylang) and [Polylang Pro](https://polylang.pro/products). Outside of this context, we do not guarantee that they provide you any value.
+Webpack configuration helpers for building Polylang projects. Provides two main functions for generating webpack configs: `getVanillaConfig` for vanilla JS/CSS files and `getReactifiedConfig` for React-based builds.
+
+## Installation
+
+```bash
+npm install @wpsyntex/polylang-build-scripts
+```
+
+## getVanillaConfig
+
+Generates webpack configurations for vanilla JS and CSS files. Creates both minified and unminified versions.
+
+**Required options:**
+- `workingDirectory` - Working directory for glob resolution (typically `__dirname`)
+- `jsBuildDirectory` - Output directory for JS files
+- `cssBuildDirectory` - Output directory for CSS files
+- `isProduction` - Enable production mode optimizations
+
+**Optional options:**
+- `jsPatterns` - Glob patterns for JS files (default: `['**/*.js']`)
+- `jsIgnorePatterns` - Patterns to ignore for JS files (default: `[]`)
+- `cssPatterns` - Glob patterns for CSS files (default: `['**/*.css']`)
+- `cssIgnorePatterns` - Patterns to ignore for CSS files (default: `[]`)
+
+**Example:**
+
+```javascript
+const { getVanillaConfig } = require( '@wpsyntex/polylang-build-scripts' );
+
+const vanillaConfigs = getVanillaConfig( {
+	workingDirectory: __dirname,
+	jsPatterns: [ '**/*.js' ],
+	jsIgnorePatterns: [ 'node_modules/**', '**/build/**', '**/*.min.js' ],
+	cssPatterns: [ '**/*.css' ],
+	cssIgnorePatterns: [ 'node_modules/**', '**/build/**', '**/*.min.css' ],
+	jsBuildDirectory: path.resolve( __dirname, 'js/build' ),
+	cssBuildDirectory: path.resolve( __dirname, 'css/build' ),
+	isProduction: mode === 'production',
+} );
+
+module.exports = vanillaConfigs;
+```
+
+## getReactifiedConfig
+
+Generates webpack configurations for React-based builds (blocks, editors). Creates minified and unminified builds with Babel transpilation.
+
+**Required options:**
+- `entryPoints` - Entry points for webpack (e.g., `{ blocks: './js/src/blocks/index.js' }`)
+- `outputPath` - Base path for output files (typically `__dirname`)
+- `libraryName` - Library name for the bundle (e.g., `'polylang'`)
+- `isProduction` - Enable production mode optimizations
+- `wpDependencies` - WordPress package dependencies to mark as externals (e.g., `['blocks', 'element', 'i18n']`)
+
+**Optional options:**
+- `additionalExternals` - Additional external dependencies (e.g., `{ jquery: 'jQuery' }`)
+
+**Example:**
+
+```javascript
+const { getReactifiedConfig } = require( '@wpsyntex/polylang-build-scripts' );
+
+const wpDependencies = [
+	'api-fetch',
+	'block-editor',
+	'blocks',
+	'components',
+	'data',
+	'element',
+	'i18n',
+];
+
+const reactConfigs = getReactifiedConfig( {
+	entryPoints: { blocks: './js/src/blocks/index.js' },
+	outputPath: __dirname,
+	libraryName: 'polylang',
+	isProduction: mode === 'production',
+	wpDependencies,
+} );
+
+module.exports = reactConfigs;
+```
+
+## Combined Usage
+
+```javascript
+const { getVanillaConfig, getReactifiedConfig } = require( '@wpsyntex/polylang-build-scripts' );
+
+module.exports = ( env, argv ) => {
+	const mode = argv.mode || 'development';
+	const isProduction = mode === 'production';
+
+	return [
+		...getVanillaConfig( { /* options */ } ),
+		...getReactifiedConfig( { /* options */ } ),
+	];
+};
+```
+
+---
+
+These scripts are meant to be used as dependencies of Polylang-related projects but can easily be adapted for any WordPress project requiring JS or React build tools.
