+1. ```cp config.json.example config.json ```
+2. Update ```"domain": "change this" ```
+3. ```.yarn/releases/yarn-4.12.0.cjs install```
+4. ```.yarn/releases/yarn-4.12.0.cjs run build```
+5. ```.yarn/releases/yarn-4.12.0.cjs start```
+
+To start for production:
+1. `docker compose up -d`
+
+Note: Use UID 10000 for data folders.

+### Important changes
+
+⚠️ **HedgeDoc 1.12.0 and onwards will require Node 20.17 or later in order to run.**  
+Since Node 18 security support was stopped over one year ago, we don't maintain backwards-compatability for that anymore.
+
+Some syntax highlighting languages have been removed and/or changed. You can find more information in
+[the highlight.js docs](https://highlightjs.readthedocs.io/en/latest/upgrade-11.html#built-in-set-of-common-languages).
