+**Q:** How do I use WASM?
+
+**A:** Currently WASM support is really incomplete.

+You can try this:
+
+`compile --reloc=none --target wasm32 -g0 --link-libc=no --no-entry mywasm.c3`
+
+This should yield an `out.wasm` file, but there is no CI running on the WASM code
+and no one is really using it yet, so the quality is low.
+

+writing something in WASM - please reach out to the developer team and we'll
+help you get things working.
