+# tinywasm-wasi
+
+Experimental WASI support for TinyWasm mainly targeting \*nix systems (Windows support is very limited). Currently unreleased.
+
+Some behavior is based on the Bytecode Alliance `wasi-common` and
+`wasmtime-wasi` implementations.
+
+## Future WASI support
+
+Preview 2 and 3 are not planned for TinyWasm, we're probably going to wait for the final WASI 1.0 release and implement that instead.
