If you google `PlantUML Gitlab` you should find some blog posts and docs, but if you are don't fancy reading this, try pasting this into a Gitlab Issue body ```plantuml Alice -> Bob: Authentication Request Bob --> Alice: Authentication Response Alice -> Bob: Another authentication Request Alice <-- Bob: Another authentication Response ``` I believe Github has similar support also.
