Merge branch 'improve_rake_import_doc' into 'master'

Improve import Documentation

Improved the documentation steps for importing bare git repositories to GitLab.

@dzaporozhets I added a step to create gitlab-satellites. Is this step really necessary, or do the satellites get created as needed?

See merge request !1234

-How to use:
+### Create a new folder inside the git repositories path. This will be the name of the new group.
 
-1. copy your bare repos under git repos_path (see `config/gitlab.yml` gitlab_shell -> repos_path)
-1. run the command below
+- For omnibus-gitlab, it is located at: `/var/opt/gitlab/git-data/repositories` by default, unless you changed
+it in the `/etc/gitlab/gitlab.rb` file.
+- For manual installations, it is usually located at: `/home/git/repositories` or you can see where
+your repositories are located by looking at `config/gitlab.yml` under the `gitlab_shell => repos_path` entry.
 
+
+### Copy your bare repositories inside this newly created folder:
+
+```
+$ cp -r /old/git/foo.git/ /home/git/repositories/new_group/
 ```
-# omnibus-gitlab
-sudo gitlab-rake gitlab:import:repos
 
-# installation from source or cookbook
-bundle exec rake gitlab:import:repos RAILS_ENV=production
+### Run the command below depending on your type of installation:
+
+#### Omnibus Installation
+
+```
+$ sudo gitlab-rake gitlab:import:repos
+```
+
+#### Manual Installation
+
+Before running this command you need to change the directory to where your GitLab installation is located:
+
+```
+$ cd /home/git/gitlab
+$ sudo -u git -H bundle exec rake gitlab:import:repos RAILS_ENV=production
 ```
