Overview
Product summary
Review the store description, core capabilities, and common use cases.
Plugin that allows displaying Plant UML diagrams embedded inside markdowns files on scm software (github, bitbucket...). No action is needed, just loading the page will display automatically the diagrams.
Warning: the diagrams are sent to the free public cloud instance https://kroki.io. Normally this is not a security issue, but you can still install Kroki on your own personal infrastructure (and change extension config).

COOL! PlantUML in Stash(bitbucket) works with includes like `!include <puml-url-file>`!
A simple extension that makes wonders with PlantUML and Mermaid diagrams on content platforms which do not support it natively (e.g. Confluence).
