 ## Getting help
 
 If you're having trouble with Lustre or not sure what the right way to do
 something is, the best place to get help is the [Gleam Discord server](https://discord.gg/Fm8Pwmy).
 You could also open an issue on the [Lustre GitHub repository](https://github.com/lustre-labs/lustre/issues).

-and the kinds of patterns that Lustre is built around.
