 First of all, you must decide on what branch your changes will be based depending of the nature of the change.

+To prepare your patch directly in the `vendor/` of an existing project (convenient to fix a bug):
+
+1. Remove the existing copy of the library: `rm -Rf vendor/api-platform/core`
+2. Reinstall the lib while keeping Git metadata: `composer install --prefer-source`
+3. You can now work directly in `vendor/api-platform/core`, create a new branch: `git checkout -b my_patch`
+4. When your patch is ready, fork the project and add your Git remote: `git remote add <your-name> [email protected]:<your-name>/core.git`
+5. You can now push your code and open your Pull Request: `git push <your-name> my_patch`
+
+Alternatively, you can also work with the test application we provide:
+
+    cd tests/Fixtures/app
+    ./console assets:install --symlink
+    symfony serve
+
+    # or if you prefer using the PHP built-in web server
+    php -S localhost:8000 -t public/

 ### Matching Coding Standards
 
 The API Platform project follows [Symfony coding standards](https://symfony.com/doc/current/contributing/code/standards.html).
 But don't worry, you can fix CS issues automatically using the [PHP CS Fixer](http://cs.sensiolabs.org/) tool:
 
-```shell
-php-cs-fixer.phar fix
-```
+    php-cs-fixer.phar fix
 
 And then, add the fixed file to your commit before pushing.
 Be sure to add only **your modified files**. If any other file is fixed by cs tools, just revert it before committing.
