LFS 
Large Git repositories become very slow and put a lot of strain on the 
GitLab server. The 
Large File Storage (
LFS) extension is used to off-load large files from a repository to a separate storage. 
For more information about LFS and GitLab please refer to the official documentation 
here.
 User Interaction with LSF Repositories 
A 
Git client with enabled LFS support is needed to work with LFS-enabled repositories.
The following examples show how to use the command line git client with LFS.
 Clone 
git clone https://gitlab.inf.ethz.ch/<group>/<project>.git
cd <project>
git config credential.helper 'cache --timeout 3600'
git pull
 
 Enable LFS for a Repository 
To enable LFS right after creating a new GitLab project follow 
these instructions. For an existing project that already contains data that should be moved to LFS 
isginf also provides 
instructions and a tool.

Are these instructions wrong, incomplete or outdated? Are they not helpful?
