 # zig-wasm-test
 A minimal Web Assembly example built from Zig's init-lib.
+
+I expanded on this great gist from @josephg.
+
+https://gist.github.com/josephg/873a21d4558fd69aeccea19c3df96672
+
+To build this project you need to follow the steps there to get a wasm enabled version of LLVM setup.
+
+## Building
+
+To build this project with a working Zig and TypeScript install at the project root just type.
+
+```
+zig build -Drelease-small
+```
+
+You need to move the resulting wasmtest.wasm file from /zig-cache/ to /www/. One has been committed if you're happy omitting this step.
+
+For good measure you can then build the TypeScript file:
+
+```
+cd www
+tsc wasmtest.ts
+```
+
+## Running
+Start the web server of your choice serving the www folder and navigate to wasmtest.html in your browser of choice. The value 7 should be output in the console.
