### Problem to solve Many folks will be reading our documentation but not understand how things with their previous tools map to GitLab CD/CI. We should provide migration information from other common CI/CD tools. ### Further details We currently have a few items related to moving from other tools: https://docs.gitlab.com/ee/README.html#coming-to-gitlab-from-another-platform, but nothing for CI specifically. We should expand our migration documentation. ### Proposal A new section in the CI docs with migration information. #### Examples [Azure migration docs](https://gitlab.slack.com/archives/C16HYA2P5/p1549891187004100)
