# S3-compatible You can use [Amazon S3](https://aws.amazon.com/s3/) or any other S3-compatible storage (like [MinIO](https://min.io) or [Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/)) to handle your image uploads in HedgeDoc. Your S3 bucket must be configured to be writeable. You just add the following lines to your configuration: (with the appropriate substitution for ``, ``, ``, and `` of course) ``` HD_MEDIA_BACKEND="s3" HD_MEDIA_BACKEND_S3_ACCESS_KEY="" HD_MEDIA_BACKEND_S3_SECRET_KEY="" HD_MEDIA_BACKEND_S3_BUCKET="" HD_MEDIA_BACKEND_S3_ENDPOINT="" ``` If you use Amazon S3, `` should contain your [Amazon Region](https://docs.aws.amazon.com/general/latest/gr/s3.html). For example: If your Amazon Region is `us-east-2`, your endpoint `` should be `s3.us-east-2.amazonaws.com`.
