+### Windows
+Since we are using the https://github.com/lxn/walk library, we need to ship a manifest.xml file, otherwise the error would be:
+
+```
+panic: Unable to create main window: TTM_ADDTOOL failed
+```
+
+To do it make sure to install the required tool:
+
+```
+$ go get github.com/akavel/rsrc
+```
+
+and build it with
+
+```
+$ rsrc -arch=386 -manifest=manifest.xml
+$ go build
+```
+
+Keep in mind that the presence of rsrc.syso file will break other builds, for example
+
+```
+$ GOOS=linux go build
+# github.com/arduino/arduino-create-agent
+/usr/lib/go/pkg/tool/linux_amd64/link: running gcc failed: exit status 1
+/usr/sbin/ld: i386 architecture of input file `/tmp/go-link-084341451/000000.o' is incompatible with i386:x86-64 output
+collect2: error: ld returned 1 exit status
