### Guide

- [Getting Started](https://lookingglass.kloudkit.com/guide/getting-started.md): Run Looking Glass and send it a request to see exactly what arrived: method, URL, headers and body.
- [Response Formats](https://lookingglass.kloudkit.com/guide/response-formats.md): Pick HTML or JSON responses from Looking Glass, copy a request as JSON or raw HTTP, and see how bodies are capped.
- [Activity Log](https://lookingglass.kloudkit.com/guide/activity-log.md): Read Looking Glass's activity log: one colored line per request, without the request's contents.
- [Building From Source](https://lookingglass.kloudkit.com/guide/building-from-source.md): Run Looking Glass from source while you work on it, or build the image yourself.

### Reference

- [Configuration](https://lookingglass.kloudkit.com/reference/configuration.md): Every Looking Glass setting, as a flag or an environment variable, and the selectors that pick the response format.
- [JSON Response](https://lookingglass.kloudkit.com/reference/json-response.md): Every field of the JSON document Looking Glass returns for a request.
