title: Configure site
description: Change collections, fields, languages, media and publishing from the browser. Admins only.
---

Open **Configuration** in the sidebar (or add `?configure=<section>` to the URL). The dialog has five sections:

| Section | What it changes | Where it is stored |
| --- | --- | --- |
| Your site | `site` in astro.config, sitemap discovery | `astro.config.*` |
| Content and Site data | Collections and their fields | `src/content.config.ts` |
| Languages | Astro `i18n` | `astro.config.*` |
| Media | Media libraries | Gitupcms database |
| Publishing | Direct commits or reviews, preview URL template | Gitupcms database |

Changes to content, site data and languages go into **one commit**, editing only the changed collections and keys. Fields written with chains or variables keep their source unless you change them; complex schemas are read-only. Unsaved edits are kept in the browser.

Labels and descriptions for collections and fields are kept in the database, not in the repo.

## Use Astro's schema files

If the repo tracks `.astro/collections/` (written by `astro sync`), detection reads the exact fields from there. **Use Astro's schema files** edits `.gitignore` to allow it.

:::warning
Schemas with variables, spreads or custom parsers can be edited in entries but not rewritten in Configure site.
