Lando is built upon Docker, but downloading Lando will also install Docker and Docker Compose locally as well.
Homebrew is the easiest way to keep it updated.
brew cask install lando
After installing, each project will need a .lando.yml file which holds the config for the particular site.
To use Lando and WordPress you will need a copy of WordPress, a database, files directory, and a theme. The database will need to be copied into the root directory of the project.
