+      FSRS Helper is an Anki add-on that supports the FSRS algorithm. It has eight main features:
+
+      - Reschedule cards based on their entire review histories.
+      - Postpone a selected number of due cards.
+      - Advance a selected number of undue cards.
+      - Balance the load during rescheduling (based on fuzz).
+      - Less Anki on Easy Days (such as weekends) during rescheduling (based on load balance).
+      - Disperse Siblings (cards with the same note) to avoid interference & reminder.
+      - Flatten future due cards to a selected number of reviews per day.
+      - Steps Stats quantify your short-term memory performance and recommend learning steps.
+
+      It can also be configured declaratively, as follows:
+
+      ```nix
+      pkgs.ankiAddons.fsrs4anki-helper.withConfig {
+        config = {
+          days_to_reschedule = 10;
+          auto_reschedule_after_sync = true;
+          display_memory_state = true;
+        };
+      }
+      ```
+
+      For a list of all configuration options, please refer to [config.md](https://github.com/open-spaced-repetition/fsrs4anki-helper/blob/${finalAttrs.src.rev}/config.md).
