-|`BACKFILL_WITH_CONTEXT` | `--backfill-with-context` | No |
+|`BACKFILL_WITH_CONTEXT` | `--backfill-with-context` | No | Set to `0` to disable fetching remote replies while backfilling profiles. This is enabled by default, but you can disable it, if it's too slow for you.
+|`BACKFILL_MENTIONED_USERS` | `--backfill-mentioned-users` | No | Set to `0` to disable backfilling any mentioned users when fetching the home timeline. This is enabled by default, but you can disable it, if it's too slow for you.
