# Environments: main, dev and stage

6 min

Every project starts with main, the live storefront. Further environments such as dev and stage are used for development and acceptance. This lesson explains what each environment is for, which settings apply per environment and how changes move from one environment to the next. Testing happens on stage first.

## Key takeaways

- main is the live environment.
- dev and stage serve development and acceptance.
- App credentials apply per environment.
