+## POT Updater
+
+Standalone tool for checking and updating POT files in CakePHP plugins.
+
+### Installation
+
+Add to your plugin's `composer.json`:
+
+```json
+{
+    "require-dev": {
+        "dereuromark/cakephp-translate": "^2.0"
+    }
+}
+```
+
+Then run:
+```bash
+composer update
+```
+
+### Usage
+
+Run from your plugin's root directory:
+
+```bash
+# Check for differences (dry-run, default)
+php vendor/dereuromark/cakephp-translate/scripts/pot-updater.php
+
+# Update the POT file
+php vendor/dereuromark/cakephp-translate/scripts/pot-updater.php --update
+
+# CI mode: fail if POT is out of date
+php vendor/dereuromark/cakephp-translate/scripts/pot-updater.php --fail-on-diff
+```
+
+### Composer Scripts
+
+Add to your plugin's `composer.json` for convenience:
+
+```json
+{
+    "scripts": {
+        "pot-check": "php vendor/dereuromark/cakephp-translate/scripts/pot-updater.php --fail-on-diff",
+        "pot-update": "php vendor/dereuromark/cakephp-translate/scripts/pot-updater.php --update"
+    }
+}
+```
+
+Then use:
+```bash
+composer pot-check   # Check if POT is up to date
+composer pot-update  # Regenerate POT file
+```
+
+### Options

+| `--update` | Actually update the POT file(s) |
+| `--verbose`, `-v` | Show detailed output including all strings |
+| `--quiet`, `-q` | Only output errors, suitable for CI |
+| `--path=<path>` | Custom paths to scan, comma-separated (default: `src,templates`) |
+| `--output=<path>` | Custom output path (default: `resources/locales`) |
+| `--domain=<name>` | Expected domain name (default: auto-detect from plugin name) |
+| `--fail-on-diff` | Exit with code 1 if differences found (for CI) |
+| `--ignore-references` | Ignore comment/reference differences |
+| `--help`, `-h` | Show help message |
+
+### Exit Codes
+
+| Code | Description |
+|------|-------------|
+| 0 | Success (POT file is up to date or was updated successfully) |
+| 1 | Differences found (when using `--fail-on-diff`) |
