+[Oban](https://github.com/sorentwo/oban) asynchronous job processor configuration.
+
+Configuration options described in [Oban readme](https://github.com/sorentwo/oban#usage):
+* `repo` - app's Ecto repo (`Pleroma.Repo`)
+* `verbose` - logs verbosity
+* `prune` - non-retryable jobs [pruning settings](https://github.com/sorentwo/oban#pruning) (`:disabled` / `{:maxlen, value}` / `{:maxage, value}`)
+* `queues` - job queues (see below)
 
 Pleroma has the following queues:
 
+* `activity_expiration` - Activity expiration
 * `federator_outgoing` - Outgoing federation
 * `federator_incoming` - Incoming federation
-* `mailer` - Email sender, see [`Pleroma.Emails.Mailer`](#pleroma-emails-mailer)
+* `mailer` - Email sender, see [`Pleroma.Emails.Mailer`](#pleromaemailsmailer)
 * `transmogrifier` - Transmogrifier

-* `scheduled_activities` - Scheduled activities, see [`Pleroma.ScheduledActivities`](#pleromascheduledactivity)
+* `scheduled_activities` - Scheduled activities, see [`Pleroma.ScheduledActivity`](#pleromascheduledactivity)
 
 Example:

-## Pleroma.Web.Federator.RetryQueue
+### Migrating `pleroma_job_queue` settings
 
-* `enabled`: If set to `true`, failed federation jobs will be retried
+`config :pleroma_job_queue, :queues` is replaced by `config :pleroma, Oban, :queues` and uses the same format (keys are queues' names, values are max concurrent jobs numbers).
-* `max_jobs`: The maximum amount of parallel federation jobs running at the same time.
+
-* `initial_timeout`: The initial timeout in seconds
+### Note on running with PostgreSQL in silent mode
-* `max_retries`: The maximum number of times a federation job is retried
+
+If you are running PostgreSQL in [`silent_mode`](https://postgresqlco.nf/en/doc/param/silent_mode?version=9.1), it's advised to set [`log_destination`](https://postgresqlco.nf/en/doc/param/log_destination?version=9.1) to `syslog`, 
+otherwise `postmaster.log` file may grow because of "you don't own a lock of type ShareLock" warnings (see https://github.com/sorentwo/oban/issues/52). 
+
+## :workers
+
+Includes custom worker options not interpretable directly by `Oban`.
+
+* `retries` — keyword lists where keys are `Oban` queues (see above) and values are numbers of max attempts for failed jobs.
+
+Example:
+
+```elixir
+config :pleroma, :workers,
+  retries: [
+    federator_incoming: 5,
+    federator_outgoing: 5
+  ]
+```

+### Migrating `Pleroma.Web.Federator.RetryQueue` settings
+
+* `max_retries` is replaced with `config :pleroma, :workers, retries: [federator_outgoing: 5]`
