 https://github.com/galaxyproject/ansible-cvmfs), and a role for adding the EPEL repository (https://github.com/geerlingguy/ansible-role-repo-epel).
 Both repositories are added as a submodule inside the `roles` directory, so make sure to use the `--recursive` option when cloning this repository:
 ```
-git clone --recursive git@github.com:EESSI/cvmfs-layer.git
+git clone --recursive git@github.com:EESSI/filesystem-layer.git
 ```
 Alternatively, clone this repository first, and init and update the required submodules later:
 ```
-git clone git@github.com:EESSI/cvmfs-layer.git
-cd cvmfs-layer
+git clone git@github.com:EESSI/filesystem-layer.git
+cd filesystem-layer
 git submodule init
 git submodule update
 ```
