+Minor Changes (e.g. Typos)
+--------------------------
+
+You may find just a typo and want to fix it. Due to GitHub's functional
+frontend, it is quite simple to create Pull Requests right in your
+browser while reading the docs on symfony.com. To do this, just click
+the **edit this page** button on the upper right corner. Beforehand,
+please switch to the right branch as mentioned before. Now you are able
+to edit the content and describe your changes within the GitHub
+frontend. When your work is done, click **Propose file change** to
+create a commit and, in case it is your first contribution, also your
+fork. A new branch is created automatically in order to provide a base
+for your Pull Request. Then fill out the form to create the Pull Request
+as described above.
