## Specification compliance
It's hard to judge, since each test in the spec testsuite covers a wide range of features (to check their interactions), but currently 33 out of 76 of the spec suite tests pass when run in Wasmtime with Lightbeam as a backend. Here's the full test output:

All the failed tests apart from `address` and `unwind` (whose failure hasn't been investigated yet) are due to features that have yet to be implemented.
## Getting involved
Our [issue tracker][issue tracker] is pretty barren right now since this is currently more-or-less a one-person project, but if you want to get involved jump into the [CraneStation Gitter room][cranestation-gitter] and someone can direct you to the right place. I wish I could say "the most useful thing you can do is play with it and open issues where you find problems" but until it passes the spec suite that won't be very helpful.
