 NOTE: **Note:**
 Make sure your hostname can be resolved on the machine itself by either a proper DNS record or an additional line in `/etc/hosts` ("127.0.0.1 hostname"). This might be necessary, for example, if you set up GitLab behind a reverse proxy. If the hostname cannot be resolved, the final installation check will fail with `Check GitLab API access: FAILED. code: 401` and pushing commits will be rejected with `[remote rejected] master -> master (hook declined)`.
 
-NOTE: **Note:**
-GitLab Shell application startup time can be greatly reduced by disabling RubyGems. This can be done in several ways:
-
-- Export `RUBYOPT=--disable-gems` environment variable for the processes.
-- Compile Ruby with `configure --disable-rubygems` to disable RubyGems by default. Not recommended for system-wide Ruby.
-- Omnibus GitLab [replaces the *shebang* line of the `gitlab-shell/bin/*` scripts](https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/1707).
