+## Contribute a feature
+
+Pull requests welcome! Consider starting with discussion or proof-of-concept first, rather than do loads of work on something and then find it doesn't fit the collective goals of the project, or something like that.
+
+At the time of writing we have a PR backlog, and generally prioritise bugfixes and contributions that have arisen through community discussion.
+
+### AI/LLM policy
+
+Strudel is a project handmade by humans, with thought and nuance. 
+
+If you have used LLMs (so called 'AI'), please detail that in the pull request. We are still developing our response to the onslaught of LLM technology, but for practical and legal reasons are currently not accepting wholly LLM-generated code. We are also not accepting PRs that add LLM features to strudel itself.
+
+There are #llm-chat and #llm-share channels on our discord. Please do not discuss or share LLM-related things outside of those channels.
 
 ## Report a Bug
 
 If you've found a bug, or some behaviour that does not seem right, you are welcome to file an [issue](https://codeberg.org/uzu/strudel/issues).

+ * to '2', it would always align '0' to the nearest cycle. You will likely want to trigger

+ *
+ * After the first use, a timeline will continue with the same 'offset'. That is, if you change

+ *
+ * Rather than incrementing a timeline to reset it, it's easier to negate it, e.g. by switching between `-2`
