GitLab

* Update README.md

I encounter some Git buffer size limits when trying to download all commits history of the repository, such as:
```error: RPC failed; curl 18 transfer closed with outstanding read data remaining
error: 5815 bytes of body are still expected
fetch-pack: unexpected disconnect while reading sideband packet
fatal: early EOF```

therefore the installation is faster and there are not errors when I download only the last version of the repository

* Fix linting issue
