We'd love your contributions! I'm sure there's more you'd like to see in yjit-metrics.
If you have questions or problems getting set up, you're probably not the only one with difficulties. You can file an issue and we'll answer as soon as we can.
We welcome GitHub Pull Requests in the usual way, though you'll need to sign a Shopify Contributor License Agreement - when you file the PR a bot should direct you through the process.
If you're looking for something to do, the issue tracker can also be helpful. We try to keep enhancements and bugs marked as such, which may help you out.
Right now documentation is mostly in the code and in the README. A PR can be a great way to correct or expand that documentation. If you see a problem, file an issue or open a PR!
