 Prolog interface for Go using [Trealla Prolog](https://github.com/trealla-prolog/trealla) and [Wasmer](https://github.com/wasmerio/wasmer-go).
 It's pretty fast. Not as fast as native Trealla, but pretty dang fast (2-5x slower than native).

 ### Caveats
 
-- Alpha status, API will change.
-- ~~Queries are findall'd and won't return answers until they terminate.~~
+- Beta status, API will probably change.
 - Doesn't work on Windows ([wasmer-go issue](https://github.com/wasmerio/wasmer-go/issues/69)).
 	- Works great on WSL.
-- ~~Currently interpreters are ephemeral, so you have to reconsult everything each query (working on this)~~.

+## WASM Binary

+This library embeds the Trealla WebAssembly binary in itself, so you can use it without any external dependencies.
+The binaries are currently sourced from [guregu/trealla](https://github.com/guregu/trealla), also [available from WAPM](https://wapm.io/guregu/trealla).
