-persist_logs
-~~~~~~~~~~~~
-
-Without this key, ``ytdl-sub`` only prints output to it's ``stdout`` and ``stderr``. If
-your configuration includes the ``persist_logs:`` key, then ``ytdl-sub`` also writes log
-files to disk.
-
-.. warning::
-
-   The log files grow rapidly if ``keep_successful_logs:`` is ``true``, the default, and
-   may fill up disk space. Set ``keep_successful_logs: false`` or prune the log files
-   regularly.
-
-For example:
 
 .. code-block:: yaml
 
   configuration:
+    dl_aliases:
+      mv: "--preset music_video"
+      u: "--download.url"

+Alias definitions to shorten :ref:`dl arguments <usage:Download Options>`. For example,
--------
-
-Each key under ``presets:`` defines a `formula` for how to format downloaded media and
-metadata. The key is the name of the preset and the value is a mapping that defines the
-preset.
-
-.. note::
-
-   The ``presets:`` key at the top of the configuration file contains multiple
-   user-defined presets, but *each preset* itself may include a ``preset:`` key that
-   defines *that preset's* base presets. For example:
-
-   .. code-block:: yaml
-
-      presets:
-        Foo Preset:
-          preset:
-            - "Jellyfin TV Show by Date"
-            - "Only Recent"
-
-preset
-~~~~~~
-
-Presets support inheritance by defining one or more parent presets:
 
 .. code-block:: yaml
 
-  presets:
+   configuration:
-    custom_preset:
+     dl_aliases:
-      ...
+       mv: "--preset music_video"
-    parent_preset:
+       u: "--download.url"
-      ...
-    child_preset:
-      preset:
-        - "parent_preset"
 
-In the example above, ``child_preset`` inherits all fields defined in ``parent_preset``.
+Simplifies
-Use parent presets where possible to reduce duplicate yaml definitions.
 
-Presets also support inheritance from multiple presets:
+.. code-block:: bash
 
-.. code-block:: yaml
+   ytdl-sub dl --preset "Jellyfin Music Videos" --download.url "youtube.com/watch?v=a1b2c3"
 
-  child_preset:
+to
-    preset:
-      - "custom_preset"
-      - "parent_preset"
 
-In this example, ``child_preset`` will inherit all fields from ``custom_preset`` and
+.. code-block:: bash
-``parent_preset`` in that order. The bottom-most preset has the highest priority. More
-specifically, presets are merged using `mergedeep`_ via `a TYPESAFE_ADDITIVE merge`_,
-which means:
 
-- if two conflicting keys arent lists or mappings, overwrite the higher priority one
+   ytdl-sub dl --mv --u "youtube.com/watch?v=a1b2c3"
-- otherwise, combine then re-evaluate
 
-If you are only inheriting from one preset, using a single string instead of a list is
+experimental
-valid, for example ``preset: "parent_preset"``, but we recommend always using a list for
+------------
-consistent readability between presets.
+Experimental flags reside under the ``experimental`` key.

+-----------
+Path to ffmpeg executable. Defaults to ``/usr/bin/ffmpeg`` for Linux,

+ffprobe_path
+------------
+Path to ffprobe executable. Defaults to ``/usr/bin/ffprobe`` for Linux,
+``./ffprobe.exe`` in the same directory as ytdl-sub for Windows.
+
+file_name_max_bytes
+-------------------
+Max file name size in bytes. Most OS's typically default to 255 bytes.
+
+lock_directory
+--------------
+The directory to temporarily store file locks, which prevents multiple instances
+of ``ytdl-sub`` from running. Note that file locks do not work on
+network-mounted directories. Ensure that this directory resides on the host
+machine. Defaults to ``/tmp``.
+
+persist_logs
+------------
+By default, no logs are persisted. Specifying this key will enable persisted logs. The following
+options are available.
+
+``keep_successful_logs``
+
+Defaults to ``True``. When this key is ``False``, only write log files for failed
+subscriptions.
+
+``logs_directory``
+
+Required field. Write log files to this directory with names like
+``YYYY-mm-dd-HHMMSS.subscription_name.(success|error).log``.
+
+umask
+-----
+Umask in octal format to apply to every created file. Defaults to ``022``.
+
+working_directory
+-----------------
+The directory to temporarily store downloaded files before moving them into their final
+directory. Defaults to ``.ytdl-sub-working-directory``, created in the same directory
+that ytdl-sub is invoked from.
