 The `dest` option sets the output directory for the build files. This should be a relative directory without leading `./`.
 
+#### ☉ option: **cgo**
+The `cgo` option sets if you want go to use cgo when building the binary. The default behavior of golang is to build with [cgo on native systems](https://pkg.go.dev/cmd/cgo#:~:text=The%20cgo%20tool%20is%20enabled,to%200%20to%20disable%20it). setting this option to `'false'` will disable cgo when building the binaries, setting it to `'true'` will enable CGO when building the binaries.
