-# Configuring Pleroma
-
-In the `config/` directory, you will find the following relevant files:
-
-* `config.exs`: default base configuration
-* `dev.exs`: default additional configuration for `MIX_ENV=dev`
-* `prod.exs`: default additional configuration for `MIX_ENV=prod`
-
-
-Do not modify files in the list above.
-Instead, overload the settings by editing the following files:
-
-* `dev.secret.exs`: custom additional configuration for `MIX_ENV=dev`
-* `prod.secret.exs`: custom additional configuration for `MIX_ENV=prod`
-
-## Uploads configuration
-
-To configure where to upload files, and wether or not 
-you want to remove automatically EXIF data from pictures
-being uploaded.
-
-    config :pleroma, Pleroma.Upload,
-      uploads: "uploads",
-      strip_exif: false
-
-* `uploads`: where to put the uploaded files, relative to pleroma's main directory.
-* `strip_exif`: whether or not to remove EXIF data from uploaded pics automatically. 
-   This needs Imagemagick installed on the system ( apt install imagemagick ).
-
-
-## Block functionality
-
-    config :pleroma, :activitypub,
-      accept_blocks: true,
-      unfollow_blocked: true,
-      outgoing_blocks: true
-
-    config :pleroma, :user, deny_follow_blocked: true
-
-* `accept_blocks`: whether to accept incoming block activities from
-   other instances
-* `unfollow_blocked`: whether blocks result in people getting
-   unfollowed
-* `outgoing_blocks`: whether to federate blocks to other instances
-* `deny_follow_blocked`: whether to disallow following an account that
-   has blocked the user in question
-
-## Message Rewrite Filters (MRFs)
-
-Modify incoming and outgoing posts.
-
-    config :pleroma, :instance,
-      rewrite_policy: Pleroma.Web.ActivityPub.MRF.NoOpPolicy
-
-`rewrite_policy` specifies which MRF policies to apply.
-It can either be a single policy or a list of policies.
-Currently, MRFs availible by default are:
-
-* `Pleroma.Web.ActivityPub.MRF.NoOpPolicy`
-* `Pleroma.Web.ActivityPub.MRF.DropPolicy`
-* `Pleroma.Web.ActivityPub.MRF.SimplePolicy`
-* `Pleroma.Web.ActivityPub.MRF.RejectNonPublic`
-
-Some policies, such as SimplePolicy and RejectNonPublic,
-can be additionally configured in their respective sections.
-
-### NoOpPolicy
-
-Does not modify posts (this is the default `rewrite_policy`)
-
-### DropPolicy
-
-Drops all posts.
-It generally does not make sense to use this in production.
-
-### SimplePolicy
-
-Restricts the visibility of posts from certain instances.
-
-    config :pleroma, :mrf_simple,
-      media_removal: [],
-      media_nsfw: [],
-      federated_timeline_removal: [],
-      reject: [],
-      accept: []
-
-* `media_removal`: posts from these instances will have attachments 
-   removed
-* `media_nsfw`: posts from these instances will have attachments marked
-   as nsfw
-* `federated_timeline_removal`: posts from these instances will be 
-   marked as unlisted
-* `reject`: posts from these instances will be dropped
-* `accept`: if not empty, only posts from these instances will be accepted
-
-### RejectNonPublic
-
-Drops posts with non-public visibility settings.
-
-    config :pleroma :mrf_rejectnonpublic
-      allow_followersonly: false,
-      allow_direct: false,
-
-* `allow_followersonly`: whether to allow follower-only posts through
-   the filter
-* `allow_direct`: whether to allow direct messages through the filter

 ## About Pleroma
 
-Pleroma is an OStatus-compatible social networking server written in Elixir, compatible with GNU Social and Mastodon. It is high-performance and can run on small devices like a Raspberry Pi.
+Pleroma is a microblogging server software that can federate (= exchange messages with) other servers that support the same federation standards (OStatus and ActivityPub). What that means is that you can host a server for yourself or your friends and stay in control of your online identity, but still exchange messages with people on larger servers. Pleroma will federate with all servers that implement either OStatus or ActivityPub, like Friendica, GNU Social, Hubzilla, Mastodon, Misskey, Peertube, and Pixelfed.
+
+Pleroma is written in Elixir, high-performance and can run on small devices like a Raspberry Pi.
 
 For clients it supports both the [GNU Social API with Qvitter extensions](https://twitter-api.readthedocs.io/en/latest/index.html) and the [Mastodon client API](https://github.com/tootsuite/documentation/blob/master/Using-the-API/API.md).
