 ## Code
 
-This repo very much has "proof of concept" / "make it work" organization. Here's a low effort explanation of what things are:
-
-* ./go – Almost everything in this directory was copied directly from the Go source. The only exceptions are go/cmd/link/link.go and go/cmd/compile/compile.go. These files basically turn the "link" and "compile" commands into libraries that can be used to link and compile an executable.
-* ./main.go – This uses the "compile" and "link" libraries to compile a single Go file into a WASM file. This is compiled to WASM and copied to ./server/build.wasm.
-* ./server – This contains all the static files for an in-browser Go playground. Most of the files are either precompiled WASM or lightly modified copies of bits and pieces from [play.golang.org](https://play.golang.org/). The most substantial work in this directory is in index.html and wasm_exec.js as wasm_exec.js needed a virtual filesystem implementation.
+* ./cmd – These are Go commands compiled for WASM. They were all produces by running commands such as `GOOS=js GOARCH=wasm go build -o ~/go/src/github.com/ccbrown/go-web-gc/compile.wasm .` from the Go source directories.
+* ./prebuilt – These are prebuilt runtime WASM files. These were produced by copying them from Go's cache after compiling anything for WASM.
