 #### Go verions
-Go version is determined using the go.mod file in the root of working directory. Go files are pulled directly from the go download [site](https://go.dev/dl/) and all go commands are installed using 'go install' after setup. If a Go version is already present the 'purge' input must be set to 'yes' to avoid errors.
+The Go version installed is determined by the version specified in the go.mod file. If not mod file is present the 'version' input is used. Go files are pulled directly from the Go download [site](https://go.dev/dl/) and all go commands are installed using 'go install' after setup. If a different version of Go is already installed the 'purge' input must be set to 'yes' to remove it and avoid errors.

 ## Issues
 This repo is a as brain-dead as I could make it and is intended to be as fast and low-level as possible. Please open an issue for any problems or suggestions.
