+
+## What it does
+
+Pinchflat is a self-hosted app for downloading YouTube content built using [yt-dlp](https://github.com/yt-dlp/yt-dlp). It's designed to be lightweight, self-contained, and easy to use. You set up rules for how to download content from YouTube channels or playlists and it'll do the rest, periodically checking for new content. It's perfect for people who want to download content for use in with a media center app (Plex, Jellyfin, Kodi) or for those who want to archive media!
+
+While you can [download individual videos](https://github.com/kieraneglin/pinchflat/wiki/Frequently-Asked-Questions#how-do-i-download-one-off-videos), Pinchflat is best suited for downloading content from channels or playlists. It's also not meant for consuming content in-app - Pinchflat downloads content to disk where you can then watch it with a media center app or VLC.
+
+If it doesn't work for your use case, please make a feature request! You can also check out these great alternatives: [Tube Archivist](https://github.com/tubearchivist/tubearchivist), [ytdl-sub](https://github.com/jmbannon/ytdl-sub), and [TubeSync](https://github.com/meeb/tubesync)
+
+## Features
+
+- Self-contained - just one Docker container with no external dependencies
+- Powerful naming system so content is stored where and how you want it
+- Easy-to-use web interface with presets to get you started right away
+- First-class support for media center apps like Plex, Jellyfin, and Kodi
+- Supports serving RSS feeds to your favourite podcast app ([docs](https://github.com/kieraneglin/pinchflat/wiki/Podcast-RSS-Feeds))
+- Automatically downloads new content from channels and playlists
+  - Uses a novel approach to download new content more quickly than other apps
+- Supports downloading audio content
+- Custom rules for handling YouTube Shorts and livestreams
+- Apprise support for notifications
+- Allows automatically redownloading new media after a set period
+  - This can help improve the download quality of new content or improve SponsorBlock tags
+- Optionally automatically delete old content ([docs](https://github.com/kieraneglin/pinchflat/wiki/Automatically-Delete-Media))
+- Advanced options like setting cutoff dates and filtering by title
+- Reliable hands-off operation
+- Can pass cookies to YouTube to download your private playlists ([docs](https://github.com/kieraneglin/pinchflat/wiki/YouTube-Cookies))
+- Sponsorblock integration
+- \[Advanced\] allows custom `yt-dlp` options ([docs](https://github.com/kieraneglin/pinchflat/wiki/%5BAdvanced%5D-Custom-yt%E2%80%90dlp-options))
+- \[Advanced\] supports running custom scripts when after downloading/deleting media (alpha - [docs](https://github.com/kieraneglin/pinchflat/wiki/%5BAdvanced%5D-Custom-lifecycle-scripts))

 ## Installation
 
-Pinchflat is designed to be self-hosted. I'm building it for my own needs which means it's designed to work well with Unraid, but it should work on any computer/server that can run Docker images.
+### Unraid
 
-I'll update with Unraid instructions once I get something in the Community Apps store. Until then, here's how you build it with Docker:
+Simply search for Pinchflat in the Community Apps store!
 
-```bash
+### Portainer
-docker build . --file selfhosted.Dockerfile -t pinchflat:dev
 
-docker run \
+> [!IMPORTANT]  
-  -p 8945:8945 \
+> See the note below about storing config on a network file share. It's preferred to store the config on a local disk if at all possible.
-  -v /Users/work/Desktop/test_volumes/config:/config \
+
-  -v /Users/work/Desktop/test_volumes/downloads:/downloads \
+Docker Compose file:
-  pinchflat:dev
+
+```yaml
+version: '3'
+services:
+  pinchflat:
+    image: keglin/pinchflat:latest
+    environment:
+      # Set the timezone to your local timezone
+      - TZ=America/New_York
+    ports:
+      - '8945:8945'
+    volumes:
+      - /host/path/to/config:/config
+      - /host/path/to/downloads:/downloads
 ```
 
-## Authentication
+### Docker
 
-Currently HTTP basic auth is optionally supported. To use it, set the `BASIC_AUTH_USERNAME` and `BASIC_AUTH_PASSWORD` environment variables when starting the container. If you don't set both of these, no authentication will be required.
+1. Create two directories on your host machine: one for storing config and one for storing downloaded media. Make sure they're both writable by the user running the Docker container.
+2. Prepare the docker image in one of the two ways below:
+   - **From GHCR:** `docker pull ghcr.io/kieraneglin/pinchflat:latest`
+     - NOTE: also available on Docker Hub at `keglin/pinchflat:latest`
+   - **Building locally:** `docker build . --file selfhosted.Dockerfile -t ghcr.io/kieraneglin/pinchflat:latest`
+3. Run the container:
+
+```bash
+# Be sure to replace /host/path/to/config and /host/path/to/downloads below with
+# the paths to the directories you created in step 1
+# Be sure to replace America/New_York with your local timezone
+docker run \
+  -e TZ=America/New_York \
+  -p 8945:8945 \
+  -v /host/path/to/config:/config \
+  -v /host/path/to/downloads:/downloads \
+  ghcr.io/kieraneglin/pinchflat:latest
+```
+
+### IMPORTANT: File permissions
+
+You _must_ ensure the host directories you've mounted are writable by the user running the Docker container. If you get a permission error follow the steps it suggests. See [#106](https://github.com/kieraneglin/pinchflat/issues/106) for more.
+
+> [!IMPORTANT]
+> It's not recommended to run the container as root. Doing so can create permission issues if other apps need to work with the downloaded media.
+
+> [!TIP]
+> If you need to run any command as root, you can run `su` from the container's shell as there is no password set for the root user.
+
+### ADVANCED: Storing Pinchflat config directory on a network share
+
+As pointed out in [#137](https://github.com/kieraneglin/pinchflat/issues/137), SQLite doesn't like being run in WAL mode on network shares. If you're running Pinchflat on a network share, you can disable WAL mode by setting the `JOURNAL_MODE` environment variable to `delete`. This will make Pinchflat run in rollback journal mode which is less performant but should work on network shares.
+
+> [!CAUTION]
+> Changing this setting from WAL to `delete` on an existing Pinchflat instance could, conceivably, result in data loss. Only change this setting if you know what you're doing, why this is important, and are okay with possible data loss or DB corruption. Backup your database first!
+
+If you change this setting and it works well for you, please leave a comment on [#137](https://github.com/kieraneglin/pinchflat/issues/137)! Doubly so if it does _not_ work well.
+
+## EFF donations
+
+Prior to 2024-05-10, a portion of all donations were given to the [Electronic Frontier Foundation](https://www.eff.org/). Now, the app doesn't accept donations that go to me personally and instead directs you straight to the EFF. [Here](https://github.com/kieraneglin/pinchflat/issues/234) are some people that have generously donated.
+
+The EFF defends your online liberties and [backed](https://github.com/github/dmca/blob/9a85e0f021f7967af80e186b890776a50443f06c/2020/11/2020-11-16-RIAA-reversal-effletter.pdf) `youtube-dl` when Google took them down.
+
+## Pre-release disclaimer
+
+This is pre-release software and anything can break at any time. I make not guarantees about the stability of this software, forward-compatibility of updates, or integrity (both related to and independent of Pinchflat). Essentially, use at your own risk and expect there will be rough edges for now.

-  # ## SSL Support
-  #
-  # To get SSL working, you will need to add the `https` key
-  # to your endpoint configuration:
-  #
-  #     config :pinchflat, PinchflatWeb.Endpoint,
-  #       https: [
-  #         ...,
-  #         port: 443,
-  #         cipher_suite: :strong,
-  #         keyfile: System.get_env("SOME_APP_SSL_KEY_PATH"),
-  #         certfile: System.get_env("SOME_APP_SSL_CERT_PATH")
-  #       ]
-  #
-  # The `cipher_suite` is set to `:strong` to support only the
-  # latest and more secure SSL ciphers. This means old browsers
-  # and clients may not be supported. You can set it to
-  # `:compatible` for wider support.
-  #
-  # `:keyfile` and `:certfile` expect an absolute path to the key
-  # and cert in disk or a relative path inside priv, for example
-  # "priv/ssl/server.key". For all supported SSL configuration
-  # options, see https://hexdocs.pm/plug/Plug.SSL.html#configure/1
-  #
-  # We also recommend setting `force_ssl` in your endpoint, ensuring
-  # no data is ever sent via http, always redirecting to https:
-  #
-  #     config :pinchflat, PinchflatWeb.Endpoint,
-  #       force_ssl: [hsts: true]
-  #
-  # Check `Plug.SSL` for all available options in `force_ssl`.
-
-  # ## Configuring the mailer
-  #
-  # In production you need to configure the mailer to use a different adapter.
-  # Also, you may need to configure the Swoosh API client of your choice if you
-  # are not using SMTP. Here is an example of the configuration:
-  #
-  #     config :pinchflat, Pinchflat.Mailer,
-  #       adapter: Swoosh.Adapters.Mailgun,
-  #       api_key: System.get_env("MAILGUN_API_KEY"),
-  #       domain: System.get_env("MAILGUN_DOMAIN")
-  #
-  # For this example you need include a HTTP client required by Swoosh API client.
-  # Swoosh supports Hackney and Finch out of the box:
-  #
-  #     config :swoosh, :api_client, Swoosh.ApiClient.Hackney
-  #
-  # See https://hexdocs.pm/swoosh/Swoosh.html#module-installation for details.
