 ## Installing Ruby
 You probably want to run ruby from a version manager like `chruby`, see [here](https://jekyllrb.com/docs/installation/macos/).
 
+## Changes checklist
+A list of things to check once in a while to make sure I haven't broken them inadvertently.
+- Mobile and web layouts looks ok.
+- Dark mode and light mode both look ok.
+- OG tags render nicely, use https://www.opengraph.xyz/
+
 ## Todo
+  - change the OG image used for the landing page so it's not just my face.
   - add humans.txt https://humanstxt.org/
   - fix the OG tags so that https://cards-dev.twitter.com/validator works
   - consider switching to using pandoc as a markdown renderer
