-Overview
---------
-``ytdl-sub`` uses two types of YAML files:
+Terminology
+-----------
 
-subscriptions.yaml
-~~~~~~~~~~~~~~~~~~
-Defines ``subscriptions``, which specify the media we want to recurrently download, like YouTube
-channels and playlists, SoundCloud artists, or any
-:yt-dlp:`yt-dlp supported site <blob/master/supportedsites.md>`. ``subscriptions`` use ``presets``
-to define how ``ytdl-sub`` should handle downloading, processing, and saving them.
+Must-know terminology:
 
-``ytdl-sub`` comes packaged with many
-:ref:`prebuilt presets <prebuilt_presets/index:Prebuilt Presets>`
-that will play nicely with well-known media players.
+- ``subscription``: URL(s) that you want to download with specific metadata requirements.
+- ``preset``: Reusable YAML configuration, that can specify anything from metadata layout, media quality, or any feature of ytdl-sub, to apply to subscriptions. A preset can inherit other presets.
+- ``prebuilt preset``: Presets that are included in ytdl-sub. These do most of the work defining plugins, overrides, etc in order to make downloads ready for player consumption.
+- ``override``: Verb describing the act of overriding something in a preset. For example, the TV Show presets practically expect you to *override* the URL variable to tell ytdl-sub where to download from.
+- ``override variables``: User-defined variables that are intended to *override* something.
+- ``subscription file``: The file to specify all of your subscriptions and some override variables.
 
-config.yaml
-~~~~~~~~~~~
-To customize ``ytdl-sub`` to beyond the prebuilt presets, you will need a ``config.yaml`` file. This
-file is where custom ``presets`` can be defined to orchestrate ``ytdl-sub`` to your very specific needs.
+Intermediate terminology:
 
-Running ytdl-sub
-~~~~~~~~~~~~~~~~
-To invoke ``ytdl-sub`` to download subscriptions, use the following command:
+- ``plugin``: Modular logic to apply to a subscription. To use a plugin, it must be defined in a preset.
+- ``config file``: An optional file where you can define custom presets and other advanced configuration.
+- ``yt-dlp``: The underlying application that handles downloading for ytdl-sub.
 
-.. tab-set-code:: 
+Advanced terminology:
 
-    .. code-block:: shell
-
-        ytdl-sub sub subscriptions.yaml
-
-    .. code-block:: powershell
-
-        ytdl-sub.exe sub subscriptions.yaml
-
-``ytdl-sub`` initially downloads all files to a defined ``working_directory``. This is a temporary
-storage spot for metadata and media files so that errors during processing- if they occur- don't
-affect your existing media library. Once all file processing is complete, your media files are
-moved to the ``output_directory``.
+- ``entry variables``: Variables that derive from a downloaded yt-dlp entry.
+- ``static variables``: Variables that do not have a dependency to entry variables.
+- ``scripting``: Syntax that allows the use of entry variables, static variables, and functions in override variables.
