+# Web IDE
+
+> Introduced in [GitLab Ultimate][ee] 10.4.
+> Brought to [GitLab CE][ce] in 10.7.
+
+The Web IDE makes it faster and easier to contribute changes to your projects
+by providing an advanced editor with commit staging.
+
+## Open the Web IDE
+
+The Web IDE can be opened when viewing a file, from the repository file list,
+and from merge requests.
+

+
+## Commit changes
+
+Changed files are shown on the right in the commit panel. All changes are
+automatically staged. To commit your changes, add a commit message and click
+the 'Commit Button'.
+
+![Commit changes](img/commit_changes.png)
+
+## Comparing changes
+
+Before you commit your changes, you can compare them with the previous commit
+by switching to the review mode or selecting the file from the staged files
+list.
+
+An additional review mode is available when you open a merge request, which
+shows you a preview of the merge request diff if you commit your changes.
