Here's how you can use this repository. Please note that this is intended to be used for local development only and not for production.

• Follow the steps mentioned under Existing app or New app.
  • This will ensure that you have a Rails app.
• In config/database.yml to update database credentials.
  • See lando/appserver/example.database.yml.
• In config/environments/development.rb allow requests from *.lndo.site.
  • Add config.hosts << /.*\.lndo\.site/.
