+# arduino101load
+multiplatform launcher for Arduino101 dfu-util flashing utility
+
+## Compiling
+
+* Download go package from [here](https://golang.org/dl/) or using your package manager
+* `cd` into the root folder of this project
+* execute
+```bash
+export GOPATH=$PWD
+go get
+go build
+```
+to produce a binary of `arduino101load` for your architecture.
+
+To cross compile for different OS/architecture combinations, execute
+```bash
+GOOS=windows GOARCH=386 go build  #windows
+GOOS=darwin GOARCH=amd64 go build #osx
+GOOS=linux GOARCH=386 go build    #linux_x86
+GOOS=linux GOARCH=amd64 go build  #linux_x86-64
