go - Not able to install cmd version of c4 from github

Question

I want to generate sha512 key for a file, When I looked through internet I found that c4 can help me to do that thing and when I open it's github repository I am not ablke to found how can I run the cmd/c4 in my ubuntu terminal. I have installed the go in my system and when I clone this repo https://github.com/Avalanche-io/c4.git And went to path cmd/c4 there is no make file present except five go files which are

1. flags.go
2. id.go
3. main.go
4. output.go
5. walker.go I am not able to implement this cmd version of c4 in my ubuntu system. Please help. As one of the answer has told me to run this command go get github.com/Avalanche-io/c4/cmd/c4 I have done this it not producing any error but as written in the answer now you can use c4 as command but it's not happening. When I use c4 ubuntu says command c4 not recognized. So now I just clone the given repo in the pc and then run the command go get * so inside the repo so it was giving following error.
