# Configuration
This file describe the configuration, it is recommended to edit the relevant *.secret.exs file instead of the others founds in the ``config`` directory.
If you run Pleroma with ``MIX_ENV=prod`` the file is ``prod.secret.exs``, otherwise it is ``dev.secret.exs``.
## Pleroma.Upload
* `uploader`: Select which `Pleroma.Uploaders` to use
-* `strip_exif`: boolean, uses ImageMagick(!) to strip exif.
+* `filters`: List of `Pleroma.Upload.Filter` to use.
+* `base_url`: The base URL to access a user-uploaded file. Useful when you want to proxy the media files via another host.
+* `proxy_remote`: If you're using a remote uploader, Pleroma will proxy media requests instead of redirecting to it.
+* `proxy_opts`: Proxy options, see `Pleroma.ReverseProxy` documentation.
+
+Note: `strip_exif` has been replaced by `Pleroma.Upload.Filter.Mogrify`.
## Pleroma.Uploaders.Local
* `uploads`: Which directory to store the user-uploads in, relative to pleroma’s working directory
-* `uploads_url`: The URL to access a user-uploaded file, ``{{base_url}}`` is replaced to the instance URL and ``{{file}}`` to the filename. Useful when you want to proxy the media files via another host.
+
+## Pleroma.Upload.Filter.Mogrify

## :instance
* `name`: The instance’s name
* `email`: Email used to reach an Administrator/Moderator of the instance
* `description`: The instance’s description, can be seen in nodeinfo and ``/api/v1/instance``

* `allow_relay`: Enable Pleroma’s Relay, which makes it possible to follow a whole instance
* `rewrite_policy`: Message Rewrite Policy, either one or a list. Here are the ones available by default:
* `Pleroma.Web.ActivityPub.MRF.NoOpPolicy`: Doesn’t modify activities (default)
* `Pleroma.Web.ActivityPub.MRF.DropPolicy`: Drops all activities. It generally doesn’t makes sense to use in production
* `Pleroma.Web.ActivityPub.MRF.SimplePolicy`: Restrict the visibility of activities from certains instances (See ``:mrf_simple`` section)
* `Pleroma.Web.ActivityPub.MRF.RejectNonPublic`: Drops posts with non-public visibility settings (See ``:mrf_rejectnonpublic`` section)
* `public`: Makes the client API in authentificated mode-only except for user-profiles. Useful for disabling the Local Timeline and The Whole Known Network.
* `quarantined_instances`: List of ActivityPub instances where private(DMs, followers-only) activities will not be send.
* `managed_config`: Whenether the config for pleroma-fe is configured in this config or in ``static/config.json``
