Configuration covers everything you set before and after your server is running: the System Console settings themselves, the subsystems Mattermost connects to, and the capabilities you turn on for your users.

## System Console settings

- [System Console settings](/administration-guide/configure/configuration-settings) - Every System Console setting, one page per section, with its `config.json` key and environment variable.
- [Store configuration in your database](/administration-guide/configure/configuration-in-your-database) - Store configuration in your Mattermost database rather than as a JSON file.
- [Environment variables](/administration-guide/configure/environment-variables) - Override configuration settings using environment variables.

## Subsystems

- [Search](/administration-guide/configure/bleve-search) - Enable Bleve search, and Chinese, Japanese, and Korean search.
- [Email](/administration-guide/configure/smtp-email) - Set up SMTP email, and customize email templates.
- [Configure Azure Blob Storage as the Mattermost file store](/administration-guide/configure/azure-blob-storage) - Use Azure Blob Storage instead of local or S3-compatible storage.

For enterprise search with Elasticsearch or OpenSearch, see the [deployment guide](/deployment-guide/scale/elasticsearch-setup).
