 **Problem**: When executing a `go get` command on Windows and you get an error about the git repository not existing.
 
-**Solution**: `go get` requires Git. If you run `go get` without Git then it will create an empty directory in your Go workspace for the library you are trying to get. Even after installing Git, you will get a similar error. To fix this, delete the empty directory (for example: if you tried to run `go get github.com/Unknwon/bra` then delete `%USERPROFILE%\go\src\github.com\Unknwon\bra`) and run the `go get` command again.
