 #### 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 either determined by the version input, or the version found in a go.mod file if the input is not set. 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.
