# Ruleset templates

Redocly CLI includes some default rulesets to get you started quickly.

To edit/adjust the rules you use in your own projects, [configure your rules](/docs/cli/v1/rules/configure-rules) accordingly to override any settings from the original ruleset.

On this page, each ruleset is included for each of the supported API description formats.
You can use this information for your own reference, or copy/paste them in order to use [separate configuration for each API](/docs/cli/v1/configuration/apis).
Consult the format-specific sections below, each code sample is formatted to be included in `redocly.yaml` directly.

More information and examples for individual rules can be found in the [built-in rules documentation](/docs/cli/v1/rules/built-in-rules).

## Minimal rulesets

The minimal rulesets are a decent baseline that you can use to selective enable more rules or extend rulesets from.

## Recommended rulesets

The default behavior is to use a recommended ruleset.
The recommended rulesets for each format are listed below.
There is also a "recommended-strict" ruleset which is identical but with all `warn` settings changed to `error`.

- More information and examples for individual rules can be found in the [built-in rules documentation](/docs/cli/v1/rules/built-in-rules).
- Add your own [configurable rules](/docs/cli/v1/rules/configurable-rules) if there's anything you need that isn't already provided as a built in rule.
