 ## Supported syscalls
 
-We support a subset of the [WASI API], though we are working on new hostcalls
+We currently support the entire [WASI API] with the exception of socket hostcalls:
-on a regular basis. We currently implement:
+- `sock_recv`
+- `sock_send`
+- `sock_shutdown`
 
-- `args_get`
+We expect these to be implemented when network access is standardised.

 ## Third-Party Code
 Significant parts of our hostcall implementations are derived from the C implementations in
