  Ideally we should replace this with a new recording that showcases the full functionality of the GitLab for Jira Cloud app.

• @anton started a discussion:

  We can look at recording a new video for these combinations (in order of importance):

  1. Installing via Atlassian Marketplace app for GitLab.com
  2. Installing manually for a self-managed instance using development mode

  I don't think we need to cover installing manually by building your own app - I am yet to see a customer who has actually done this.
