-
-To show the *who to follow* panel, edit `config/prod.secret.exs` in the Pleroma backend. Following code activates the *who to follow* panel:
-
-```elixir
-config :pleroma, :suggestions,
-  enabled: true,
-  third_party_engine:
-    "http://vinayaka.distsn.org/cgi-bin/vinayaka-user-match-suggestions-api.cgi?{{host}}+{{user}}",
-  timeout: 300_000,
-  limit: 40,
-  web: "https://vinayaka.distsn.org"
-
-```
-
-`config/config.exs` already includes this code, but `enabled:` is `false`.
-
-`/api/v1/suggestions` is also provided when *who to follow* panel is enabled.
-
-For advanced customization, following code shows the newcomers of the fediverse at the *who to follow* panel:
-
-```elixir
-config :pleroma, :suggestions,
-  enabled: true,
-  third_party_engine:
-    "http://vinayaka.distsn.org/cgi-bin/vinayaka-user-new-suggestions-api.cgi?{{host}}+{{user}}",
-  timeout: 60_000,
