+# Whoa, whats going on here?
+
+We are transforming the Mermaid repository to a so called mono-repo. This is a part of the effort to decouple the diagrams from the core of mermaid. This will:
+
+- Make it possible to select which diagrams to include on your site
+- Open up for lazy loading
+- Make it possible to add diagrams from outside of the Mermaid repository
+- Separate the release flow between different diagrams and the Mermaid core
+
+As such be aware of sime changes..
+
+# We use pnpm now
+
+# The source code has moved
+
+It is now localted in the src forunder for respoective package located as subfoders in packages.
