# Chromium policy definitions
This directory houses the data templates used Chromium browser and OS policies.
# Policy definitions
Policies are defined under
[policy_definitions](https://cs.chromium.org/chromium/src/components/policy/resources/templates/policy_definitions).
Every subdirectory represents a policy group.
* To create a new policy group, create a new directory named after the new group
under [policy_definitions](https://cs.chromium.org/chromium/src/components/policy/resources/templates/policy_definitions).
* To create a new policy, create a yaml file under the appropriate group.
The name of the file will be the name of the policy.
For more information on policy creation, visit [add_new_policy.md](/docs/enterprise/add_new_policy.md#adding-a-new-policy).
* To remove a policy, more information can be found at [add_new_policy.md](/docs/enterprise/add_new_policy.md#removing-support-for-a-policy).
* If the policy was released, mark it as deprecated, add an end milestone in the
supported_on field of that policy. You may only remove support for a policy
after the last milestone of support has passed.
* If the policy was not released, delete the yaml file of that policy, and
replace its name in [policies.yaml](https://cs.chromium.org/chromium/src/components/policy/resources/templates/policies.yaml) by an empty string.
* Removing policies also requires deleting all references to that policy in the code.
