I have a couple of github repos that I want to configure and start using one lando file ? Do I have to use multiple lando files or can it be just one.
Lando is for defining a development environment.
considering that lando init is for creating a .lando.yml for a given recipe and with code from a given source.
It initializes a codebase for usage with Lando.
So this seems specific for a given code-base, and should be created in each of your GitHub repositories.
