+# Go Builder
+
+This action is adapted from https://github.com/sosedoff/actions/tree/master/golang-build
+
+Github Action to cross-compile Go project binaries for multiple platforms in a single run.
+
+Uses `golang:1.11` Docker image with `CGO_ENABLED=0` flag.
+
+## Usage
+
+Basic usage:
+
+```
+action "build" {
+  uses = "./actions/build"
+}
+```
+
+Basic workflow configuration will compile binaries for the following platforms:
+
+- linux: 386/amd64
+- darwin: 386/amd64
+- windows: 386/amd64 
+
+Alternatively you can provide a list of target architectures in `arg`:
+
+```
+action "build" {
+  uses = "./actions/build"
+  args = "linux/amd64 darwin/amd64"
+}
+```
+
+Example output:
+
+```
+----> Setting up Go repository
+----> Building project for: darwin/amd64
+  adding: test-go-action_darwin_amd64 (deflated 50%)
+----> Building project for: darwin/386
+  adding: test-go-action_darwin_386 (deflated 45%)
+----> Building project for: linux/amd64
+  adding: test-go-action_linux_amd64 (deflated 50%)
+----> Building project for: linux/386
+  adding: test-go-action_linux_386 (deflated 45%)
+----> Building project for: windows/amd64
+  adding: test-go-action_windows_amd64 (deflated 50%)
+----> Building project for: windows/386
+  adding: test-go-action_windows_386 (deflated 46%)
+----> Build is complete. List of files at /github/workspace/.release:
+total 16436
