 ### Channels
-- When adding a channel, Tube Archivist will ignore the channel page size as described above, this is meant for an initial download of the whole channel. You can still ignore selected videos from the queue before starting the download.

-- Download a complete channel including shorts and streams by entering:

-    - Channel URL: `https://www.youtube.com/channel/UCBa659QWEk1AI4Tg--mrJ2A`

+Add a [channel](urls.md#channel) to download the complete channel, or a [channel sub page](urls.md#channel-sub-pages) to download a partial channel.
 
 ### Playlist
-- Add a playlist ID or URL to add every available video in the list to the download queue, for example `https://www.youtube.com/playlist?list=PL96C35uN7xGLLeET0dOWaKHkAlPsrkcha` or `PL96C35uN7xGLLeET0dOWaKHkAlPsrkcha`.
-- When adding a playlist to the queue, this playlist will automatically get [indexed](playlists.md#playlist-detail).
-- When you add a link to a video in a playlist, Tube Archivist assumes you want to download only the specific video and not the whole playlist, for example `https://www.youtube.com/watch?v=CINVwWHlzTY&list=PL96C35uN7xGLLeET0dOWaKHkAlPsrkcha` will only add one video, `CINVwWHlzTY`, to the queue.
+Add a [playlist](urls.md#playlist) to download all videos in the list. When adding a playlist to the queue, this playlist will automatically get [indexed](playlists.md#playlist-detail).
 
 ## The Download Queue
 Below the three buttons you find the download queue. New items will get added at the bottom of the queue, the next video to download once you click on **Start Download** will be the first in the list.

+description: How URLs from YouTube get parsed
+---
+
+# URLs
+This document describes how Tube Archivist identifies and treats links from YouTube.
+
+!!! note
+    Application logic of Tube Archivist is tied only to the IDs, not the names.
+
+## Video
+A video ID is **11** characters long, e.g. `2tdiKTSdE9Y`.
+
+Urls can have several forms:  
+
+- Watch URL: Regular URLs so will see while browsing YouTube, with the path */watch* and a *v* parameter, e.g. `https://www.youtube.com/watch?v=2tdiKTSdE9Y`
+- Share URL: Link you will get when you click on *share* on a video, e.g. `https://youtu.be/2tdiKTSdE9Y`
+- Shorts URL: e.g. `https://www.youtube.com/shorts/U80grnZJm_8`
+
+## Channel
+A channel ID is **24** characters long, e.g. `UCBa659QWEk1AI4Tg--mrJ2A`.
+
+Channel URLs can have these forms, all will get translated to the ID:
+
+- ID URL: With a *channel* path, e.g. `https://www.youtube.com/channel/UCBa659QWEk1AI4Tg--mrJ2A`
+- Channel Handle: Starting with a `@` this handle is personal and unique, e.g. `@TomScottGo`
+- Alias URL: Based off the channel handle, e.g. `https://www.youtube.com/@TomScottGo`
+
+### Channel sub pages
+Tube archivist can separate between different subpages:
+
+- Videos only: `https://www.youtube.com/@IBRACORP/videos`
+- Shorts only: `https://www.youtube.com/@IBRACORP/shorts`
+- Streams only: `https://www.youtube.com/@IBRACORP/streams`
+- Every other channel sub page will default to download all, for example `https://www.youtube.com/@IBRACORP/featured` will download videos and shorts and streams.
+
+## Playlist
+A playlist ID can be `34`, `26` or `18` characters long, e.g. `PL96C35uN7xGLLeET0dOWaKHkAlPsrkcha`
+
+- Playlist URLs start with a *playlist* path and has a *list* parameter, e.g. `https://www.youtube.com/playlist?list=PL96C35uN7xGLLeET0dOWaKHkAlPsrkcha`
+
+### Playlist vs Video URLs
+While browsing YouTube videos in Playlists, you might encounter URLs looking like that: `https://www.youtube.com/watch?v=QPZ0pIK_wsc&list=PL96C35uN7xGLLeET0dOWaKHkAlPsrkcha`. As established above, based on the */watch* path and the *v* parameter, Tube Archivist will treat this as a video with the ID `QPZ0pIK_wsc` and **not** as a playlist. If you mean the playlist, you can easily grab the correct ID from the URL, e.g. `PL96C35uN7xGLLeET0dOWaKHkAlPsrkcha`.
