A GitLab account is automatically created, if you sign in using your JSC account.
LFS is a comfortable and efficient way to store large binaries.
With GitLab Pages you can create static websites for your GitLab projects, groups, or user accounts. You can use any static website generator: Jekyll, Hugo and so on.
GitLab can show whether a commit is verified or not when signed with a GPG key. All you need to do is upload the public GPG key in your profile settings.
To get started with Gitlab+GPG see the docs.
