 ## Build for microcontrollers
 
 In `./platforms/` folder you can find projects for different targets. Some of them are using Platformio, so you can follow the regular pio build process. Others have custom instructions in respective `README.md` files.

+## Running WebAssembly spec tests
+
+To run spec tests, you need `python3`
+
+```sh
+cd test
+python3 ./run-spec-test.py

+
+It will automatically download, extract, run the WebAssembly core test suite.
+
+## Running WASI test
+
+Wasm3 comes with a set of benchmarks and test programs (prebuilt as `WASI` apps) including `CoreMark`, `C-Ray`, `Brotli`, `mandelbrot`, `smallpt` and `wasm3` itself.
+
+This test will run all of them and verify the output:
+
+```sh
+./run-wasi-test.py
+```
+
+It can be run against other engines as well:
+
+```sh
+./run-wasi-test.py --exec wasmtime                    # [PASS]
+./run-wasi-test.py --exec "wavm run"                  # [PASS]
+./run-wasi-test.py --exec "wasmer run"                # [PASS]
+./run-wasi-test.py --exec "wasmer-js run"             # [PASS]
+./run-wasi-test.py --exec $WAMR/iwasm --timeout=300   # [PASS, but very slow]
+./run-wasi-test.py --exec $WAC/wax   --timeout=300    # [FAIL, crashes on most tests]
+```
