+1. Clone or fork this repo INCLUDING its submodule: `git clone --recurse-submodules ssh://gitea@git.astrolabe.coop:2106/AstrolabeCAE/SiteWebAstrolabe_public.git`
 3. `cd` into the project directory (SiteWebAstrolabe_public) and run `npm install`
 4. Once all the dependencies are installed run `npm start`
 5. Open your browser at `http://localhost:8080` and away you go!
 
+If you don't have the members data (page /equipe), you may have done a simple (non-recursive) clone. In this case, populate with member data by running `git submodule update --init --recursive`. Also, check that you do have the rights for the https://git.astrolabe.coop/AstrolabeCAE/SiteWebAstrolabe_private repository.
+
+If you need to get the latest commits of the SiteWebAstrolabe_private repo, you can do a `git submodule update --remote`.
