 ### Enabling Authentication
 
 To enable authentication for `weed mini`, use one of the following methods:
+
 1. **Environment Variables**: Set `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` before starting.
-   ```bash
+
+```bash
 export AWS_ACCESS_KEY_ID=any
 export AWS_SECRET_ACCESS_KEY=any
 export S3_ENDPOINT=http://localhost:8333
 weed mini -dir=/data
 ```
+
 2. **Config File**: Use the `-s3.config` flag with a JSON credentials file.
-   ```bash
-   weed mini -dir=/data -s3.config=s3.config
-   ```
+
+```bash
+weed mini -dir=/data -s3.config=s3.config
+```
+
 3. **Dynamic Configuration**: Start normally, then add users through the **Admin UI** or **weed shell**. The server will automatically switch from "Allow All" to "Authentication Required" mode.
