 #+END_SRC
+* Using Git from Rstudio
+** Cloning a repository
+Open RStudio and do the following steps:
+- Create a new version controled project: =File / New Project / Version
+  Control=
+  #+BEGIN_CENTER
+  file:rstudio_images/new_project.png
+
+  file:rstudio_images/git.png  
+  #+END_CENTER
+- Get the url from your gitlab repository:
+  #+BEGIN_CENTER
+  file:rstudio_images/adresse_depot.png  
+  #+END_CENTER
+- Indicate this URL in the "Repository URL" field (/you may want to
+  prefix this URL with =xxx@= where =xxx= is/ /your Gitlab id to avoid
+  repeatedly giving it later on/). 
+  #+BEGIN_CENTER
+  file:rstudio_images/clone.png  
+  #+END_CENTER
+- If you're behind a proxy, git should be configured
+  accordingly. Check the [[https://www.fun-mooc.fr/courses/course-v1:inria+41016+session01bis/jump_to_id/7508aece244548349424dfd61ee3ba85]["Dealing with proxies" section]].
+- Git will then connect to Gitlab and fetch a whole copy of the
+  repository.
+- RStudio should restart in a mode related to Git:
+  #+BEGIN_CENTER
+  file:rstudio_images/rstudio.png  
+  #+END_CENTER
+- The file manager on the right, allows you to browse the version
+  controled repository.
+** Modifying a file
+- Open =Module2/exo1/toy_document.Rmd= and perform a simple
+  modification.
+- Save
+- Go to the Git menu to commit
+  #+BEGIN_CENTER
+  file:rstudio_images/commit.png
+
+  file:rstudio_images/commit2.png
+  #+END_CENTER
+- Select the lines to commit and then click on =commit=
+  #+BEGIN_CENTER
+  file:rstudio_images/commit5.png  
+  #+END_CENTER
+  Your modifications have now been commited on your local
+  machine. They haven't been propagated to GitLab yet.
+- Click on =push= to propagate them on GitLab
+  #+BEGIN_CENTER
+  file:rstudio_images/push.png
+
+  file:rstudio_images/push2.png
+
+  file:rstudio_images/push3.png
+  #+END_CENTER
+  *NB*: You won't be able to propagate your modifications on GitLab if
+  some modifications have been done on GitLab in the meantime. 
+  file:rstudio_images/push4.png
+- You should first merge these remote modifications locally. Click on
+  =pull= to get these modifications on your machine.
