+* NewPipe uses the [PrettyTime](https://github.com/ocpsoft/prettytime) library to display localized versions of dates and times. It needs to be translated, too.

-NewPipe does not use any Google framework libraries, nor the YouTube API. Websites are only parsed to fetch required info, so this app can be used on devices without Google services installed. Also, you don't need a YouTube account to use NewPipe, which is copylefted libre software.

 ### Supported Services
 
-NewPipe supports multiple services. Our [docs](https://teamnewpipe.github.io/documentation/) provide more info on how a new service can be added to the app and the extractor. Please get in touch with us if you intend to add a new one. Currently supported services are:
+NewPipe currently supports these services:
 
-* YouTube
-* SoundCloud \[beta\]
-* media.ccc.de \[beta\]
-* PeerTube instances \[beta\]
-* Bandcamp \[beta\]
+<!-- We link to the service websites separately to avoid people accidentally opening a website they didn't want to. -->
+* YouTube ([website](https://www.youtube.com/)) and YouTube Music ([website](https://music.youtube.com/)) ([wiki](https://en.wikipedia.org/wiki/YouTube))
+* PeerTube ([website](https://joinpeertube.org/)) and all its instances (open the website to know what that means!) ([wiki](https://en.wikipedia.org/wiki/PeerTube))
+* Bandcamp ([website](https://bandcamp.com/)) ([wiki](https://en.wikipedia.org/wiki/Bandcamp))
+* SoundCloud ([website](https://soundcloud.com/)) ([wiki](https://en.wikipedia.org/wiki/SoundCloud))
+* media.ccc.de ([website](https://media.ccc.de/)) ([wiki](https://en.wikipedia.org/wiki/Chaos_Computer_Club))
 
-<!-- Hidden span to keep old links compatible. -->
+As you can see, NewPipe supports multiple video and audio services. Though it started off with YouTube, other people have added more services over the years, making NewPipe more and more versatile!
+
+Partially due to circumstance, and partially due to its popularity, YouTube is the best supported out of these services. If you use or are familiar with any of these other services, please help us improve support for them! We're looking for maintainers for SoundCloud and PeerTube.
+
+If you intend to add a new service, please get in touch with us first! Our [docs](https://teamnewpipe.github.io/documentation/) provide more information on how a new service can be added to the app and to the [NewPipe Extractor](https://github.com/TeamNewPipe/NewPipeExtractor).
+
+## Description
+
+NewPipe works by fetching the required data from the official API (e.g. PeerTube) of the service you're using. If the official API is restricted (e.g. YouTube) for our purposes, or is proprietary, the app parses the website or uses an internal API instead. This means that you don't need an account on any service to use NewPipe.
+
+Also, since they are free and open source software, neither the app nor the Extractor use any proprietary libraries or frameworks, such as Google Play Services. This means you can use NewPipe on devices or custom ROMs that do not have Google apps installed.
+
+### Features
+
+* Watch videos at resolutions up to 4K
+* Listen to audio in the background, only loading the audio stream to save data
+* Popup mode (floating player, aka Picture-in-Picture)
+* Watch live streams
+* Show/hide subtitles/closed captions
+* Search videos and audios (on YouTube, you can specify the content language as well)
+* Enqueue videos (and optionally save them as local playlists)
+* Show/hide general information about videos (such as description and tags)
+* Show/hide next/related videos
+* Show/hide comments
+* Search videos, audios, channels, playlists and albums
+* Browse videos and audios within a channel
+* Subscribe to channels (yes, without logging into any account!)
+* Get notifications about new videos from channels you're subscribed to
+* Create and edit channel groups (for easier browsing and management)
+* Browse video feeds generated from your channel groups
+* View and search your watch history
+* Search and watch playlists (these are remote playlists, which means they're fetched from the service you're browsing)
+* Create and edit local playlists (these are created and saved within the app, and have nothing to do with any service)
+* Download videos/audios/subtitles (closed captions)
+* Open in Kodi
+* Watch/Block age-restricted material

 ## Installation and updates
 You can install NewPipe using one of the following methods:
  1. Add our custom repo to F-Droid and install it from there. The instructions are here: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
  2. Download the APK from [GitHub Releases](https://github.com/TeamNewPipe/NewPipe/releases) and install it.
- 3. Update via F-Droid. This is the slowest method of getting updates, as F-Droid must recognize changes, build the APK itself, sign it, then push the update to users.
+ 3. Update via F-Droid. This is the slowest method of getting updates, as F-Droid must recognize changes, build the APK itself, sign it, and then push the update to users.
  4. Build a debug APK yourself. This is the fastest way to get new features on your device, but is much more complicated, so we recommend using one of the other methods.
+ 5. If you're interested in a specific feature or bugfix provided in a Pull Request in this repo, you can also download its APK from within the PR. Read the PR description for instructions. The great thing about PR-specific APKs is that they're installed side-by-side the official app, so you don't have to worry about losing your data or messing anything up.
 
-We recommend method 1 for most users. APKs installed using method 1 or 2 are compatible with each other, but not with those installed using method 3. This is due to the same signing key (ours) being used for 1 and 2, but a different signing key (F-Droid's) being used for 3. Building a debug APK using method 4 excludes a key entirely. Signing keys help ensure that a user isn't tricked into installing a malicious update to an app.
+We recommend method 1 for most users.

Signing keys help ensure that a user isn't tricked into installing a malicious update to an app. When using method 5, each APK is signed with a different random key supplied by GitHub Actions, so you cannot even update it. You will have to backup and restore the app data each time you wish to use a new APK.
 
 In the meanwhile, if you want to switch sources for some reason (e.g. NewPipe's core functionality breaks and F-Droid doesn't have the latest update yet), we recommend following this procedure:
 1. Back up your data via Settings > Content > Export Database so you keep your history, subscriptions, and playlists

-Whether you have ideas, translations, design changes, code cleaning, or real heavy code changes, help is always welcome.
-The more is done the better it gets!
+<b>Note: when you're importing a database into the official app, always make sure that it is the one you exported _from_ the official app. If you import a database exported from an APK other than the official app, it may break things. Such an action is unsupported, and you should only do so when you're absolutely certain you know what you're doing.</b>
