# Environments

> An environment is the place you test: name, base URL, description, and default flag. Create it on the Environments page.

An environment is the URL you used to paste in the spreadsheet header: staging, UAT, "the implementation site."

## Fields

* **name:** Staging, QA, Production (prod is for post-release checks, not most UAT)
* **base\_url:** where the app lives
* **description:** credentials hints, VPN, "use Chrome"
* **is\_default:** the one cycles should pick

**Add First Environment** on **Environments**. Cycles point at an environment so runs open the right place.

## Update and delete

The service layer can update and delete environments. The list page may **only create**. If you cannot rename in the UI, that's a current page gap, not you missing a hidden menu. Don't promise clients a full env admin screen.

You still need at least one environment to run in a sane way. [Can't start](/troubleshooting/cant-start).
