 ### Downloading LMGC90 ###
 
+Currently the graphical interface provided with the `git` software cannot be used
+to download LMGC90. The only available way is to use a terminal, to do this run
+the `Git BASH` software recently installed. This will open a black window in which
+you will be able to run commands executed when typing the *return* key.
+
+First you must choose a directory in which you will download the software. In this example
+let's say that a *LMGC* directory has been created on the desktop. You must run the
+following commands to place the terminal in the corresponding directory:
+
+```shell
+cd Desktop/LMGC
+```
+
+Then to download:
+
+```shell
+export GIT_SSL_NO_VERIFY=True
+git clone https://git-xen.lmgc.univ-montp2.fr/lmgc90/lmgc90_user.git
+```

+This should create a directory *lmgc90_user*. Once the previous line has been run, all next `git` commands should be run from this *lmgc90_user* directory.
+
+To update to the latest state run from a terminal in your *lmgc90_user*:
+
+```
+git pull origin master
+```
