+This is a small Minecraft tool written in PHP to fix missing end or nether dimension compound tags in the level.dat file. If the tags are missing, the portals do not work.
+
+# Usage CLI
+
+```bash
+php repair.php input_file [output_file]
+```
+
+If no output file path is given, the output directory is the current directory.
+
+# Usage PHP code
+
+```php
+$fileName = 'level.dat'
+$fileContent = file_get_contents($filename)
+$creabit = new Creabit($fileContent)
+file_put_contents($fileName, $creabit->repair());
+```
