bash - Git Checkout Latest Tag

I'm writing a shell script and I'm looking to checkout the latest version of repo. Specifically I want to break this process apart into multiple steps.

  1. I want to save the repositories latest tag into a variable
  2. Print out Checking out version: XX
  3. Checkout the latest tag

I've seen similar questions but I don't see how to save the name of the tag into a variable (probably because I'm a noob with shell scripts).

# Get new tags from remote
git fetch --tags

# Get latest tag name
latestTag=$(git describe --tags `git rev-list --tags --max-count=1`)

# Checkout latest tag
git checkout $latestTag
