How to install gitversion on Ubuntu 18.04.4?

I am trying to install gitversion in our build server in Ubuntu 18.04.4 LTS (GNU/Linux 5.3.0-1030-aws x86_64). The documentation has very little instruction. I found tar.gz file in github (here) upon uncompressing using following command I only got a single file named "gitversion".

wget https://github.com/GitTools/GitVersion/releases/download/5.3.7/gitversion-ubuntu.18.04-x64-5.3.7.tar.gz
tar -xvf gitversion-ubuntu.18.04-x64-5.3.7.tar.gz

I am completely lost after that. Judging by the lack of instruction in documentation, I am guessing this should be simple or obvious. May be the problem is I am newbie.

I also looked here. but this instruction is using a zip file that is not available for latest release.

Thanks in advance.

wget https://github.com/GitTools/GitVersion/releases/download/5.3.7/gitversion-ubuntu.18.04-x64-5.3.7.tar.gz
tar -xvf gitversion-ubuntu.18.04-x64-5.3.7.tar.gz
sudo mv gitversion /usr/local/bin
