Reference Configuration

Reference Configuration outlines the YAML profile shape for ports, DNS, proxies, proxy groups and rules, with safe editing notes.

Overview

A Clash configuration file is a YAML profile that describes ports, DNS behavior, proxy definitions, proxy groups and routing rules. GUI clients may hide part of it, but the same structure is still used underneath.

Minimal shape

Real profiles usually replace the empty lists with provider-generated proxies and groups. If you edit the file manually, keep indentation consistent and avoid tabs.

Editing rules safely

  • Back up a working profile before changing it.
  • Validate YAML after every edit.
  • Change one block at a time, then reload the client.
  • Read logs when the client refuses to start or shows an empty proxy list.

Common status messages

The most common mistakes are invalid indentation, missing commas in rules, duplicated group names, unsupported fields for the selected core, and provider URLs that return HTML instead of YAML.

Reference examples

These examples mirror the corresponding Chinese documentation page so the English page carries the same configuration material.
