Some times, you can need to make a quick modifictaion in your source code without having to clone the project in Eclipse Che. You can perform quick modification right inside Gitlab using the Gitlab Editor.

In the following Example, I want to edit the Dockerfile of my code.

1- I click on the button Web IDE

2- I have just to click on the file to open the editor on the right and to make my modification.

3- I click on the button Commit to save the modification, and that's all.

Don't forget to synchronise your project in Eclipse che to have this modification, if you have a copy in Eclipse che.
