+# Set Default Quota per User Role
+
+You can define default storage quotas for specific user roles in OpenCloud by configuring the proxy service. This ensures that any newly created user with a given role automatically receives the specified quota.
+
+## Define Role-Based Quotas in `proxy.yaml`
+
+To configure quotas, edit the `opencloud.proxy.yaml` file and add the `role_quotas` section with role IDs and the desired quota in bytes:
+
+```bash
+nano opencloud-compose/config/opencloud.proxy.yaml
+```
+
+Example configuration:
+
+```yaml
+role_quotas:
+  'd7beeea8-8ff4-406b-8fb6-ab2dd81e6b11': 1073741824
+```
+
+This assigns a 1 GB quota to all new users with the "User" role.
+
+## Role IDs
+
+Use the following role IDs to configure different quotas:
+
+- User:  
+  `d7beeea8-8ff4-406b-8fb6-ab2dd81e6b11`
+
+- SpaceAdmin:  
+  `2aadd357-682c-406b-8874-293091995fdd`
+
+- Admin:  
+  `71881883-1768-46bd-a24d-a356a2afdf7f`
+
+:::note
+Quota values are defined in bytes.
+:::
+
+## Mount the Configuration in Docker
+
+To apply the configuration, mount the updated `proxy.yaml` into your Docker container.
+
+1. Open the `docker-compose.yaml` file:
+
+```bash
+nano opencloud-compose/docker-compose.yaml
+```
+
+2. Add the following line under the `volumes` section for the proxy container:
+
+```yaml
+- ./config/opencloud/proxy.yaml:/etc/opencloud/proxy.yaml
+```
+
+## Apply the Changes
+
+Restart the OpenCloud container to apply the new configuration:
+
+```bash
+docker compose up -d
+```
+
+## Result
+
+All newly created users who receive a role defined in the `role_quotas` section will automatically have the specified quota assigned.
+
+:::info
+This configuration does **not** affect existing users. Only new users will receive the default quota.
