+# Contribute using Gitlab Web IDE
+
+This shows how to use Gitlab Web IDE to add or edit a howto-card:
+
+Before you start, please make sure that you have the correct access rights to edit the repository.
+
+*Note: If you do not have the rights to edit the repository, you can either ask for permissions by contacting the repository maintainers, or use your own copy of the repository (called a `fork`). Please follow [these instructions]](create-fork) to obtain your copy (fork). You can then [mirror the fork automatically](/cards/contribute:mirror-fork) to keep in sync.*
+
+A clear difference between editing a file in a git-tracked repository compared to a live document is that you can make an edit directly, and then suggesting the change. You can make this edit on your own version (called a `branch`), and then request to merge your changes into the main repository (through opening a `merge request`).
+
+## Select the development version (branch)
+
+Before making an edit, please follow the instructions in the `README.md` file. Often, a standard development scheme is followed. For instance, there is a `master` branch (usually referred to as the stable version of the repository) and a `develop` branch (the unstable development version of the repository). There can also be lots of other versions in the same repository. In order to select the development version (`develop` branch), click on the drop-down menu and select `develop`

+
+The page will refresh and show the repository contents. On the top left of the page, you can see that the `develop` branch has been selected.
+
+<img src="img/img2.png">
+
+## Open the web editor (Web IDE)
+
+You can now open the web editor (integrated development environment or IDE) by clicking on the Web IDE button:
+
+<img src="img/img3.png">
+
+Now, you can make changes to the file you wish. As an example, we will make a change to the file `privacy_policy.md`. Select the file `privacy_policy.md` from the list on the left.
+
+<img src="img/img4.png">
+
+Now, edit the file the way you want. For instance. we add a line with `test` in the first section:
+
+<img src="img/img5.png">
+
+*Note: You can see a green line on the left side of it, indicating that a new line has been added. The vertical line turns blue if a line is edited.*
+
+## Committing your change
+
+As already mentioned, a change has to be proposed, and will then be reviewed. The system used is through `merge requests`. Now, as you have edited the file, you can see that on the bottom left of the window, a blue button appeared:
+
+<img src="img/img6.png">
+
+*Note: There is no `Save` button. You save your work by committing changes.*
+
+When clicking on submit, the page changes to display the changes made:
+
+<img src="img/img7.png">
+
+You can see that a green line has been added on the right column. The left column displays the original file (of the `develop` branch).
+
+On the bottom left, you can see a form for committin the change. Here, you have to select `Create a new branch`. This is **important**.
+
+<img src="img/img8.png">
+
+You can also add a specific commit message to label the change properly. The name of the branch is generated automatically. You can, if you want, change it as well.
+
+Then, select `Start a new request` when you are ready to start the submission process and hit the `Commit` button.
+
+## Submitting your merge request
+
+After hitting the `Commit` button, you will be redirect to the submission page for your merge request:
+
+<img src="img/img9.png">
+
+Please make sure that you see that you are proposing to merge your branch (version) into the `develop` branch. This is shown at the top of the page:
+
+<img src="img/img10.png">
+
+You can then fill our the merge request submission form. and select, for instance, an `Assignee`.
+
+Good practice is to select `Delete source branch when merge request is accepted.`
+
+Under `Changes`, you can see the added line:
+
+<img src="img/img11.png">
+
+All that is left now is to submit the merge request by clicking on `Submit merge request`. That is it.
