# 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
+
