+# ispx for Go+ Builder
+
+## Introduction
+
+This package (ispx) is forked from [goplus/ispx](https://github.com/goplus/ispx) with some modification for fs, so that we can run a project packed in a zip file.
+
+## Prepare
+
+```sh
+./build.sh
+cp $GOROOT/misc/wasm/wasm_exec.js ./
+```
+
+Then put zip file of the project you want to test under directory `ispx/`, with name `test.zip`.
+
+## Run
+
+Serve directory `ispx/` with any HTTP server & open `index.html`
+
+## Upgrade deps
+
+If we want to upgrade deps like [spx](https://github.com/goplus/spx). First Modify `go.mod` to upgrade dependencies, then do
+
+```sh
+go mod tidy
+go install github.com/goplus/igop/cmd/qexp@latest # `qexp` is required to do `go generate`
+go generate # `qexp` will update `pkg/github.com/goplus/spx/export.go`, see detail in `main.go` (`//go:generate qexp ...`)
+```
