-## Detection parameters
+## Limitations
 
-Show introductions will be detected if they are:
+* SyncPlay is not (yet) compatible with any method of skipping due to the nature of how the clients are synced. 
 
-* Located within the first 25% of an episode or the first 10 minutes, whichever is smaller
+## [Detection parameters](https://github.com/intro-skipper/intro-skipper/wiki#detection-parameters)
-* Between 15 seconds and 2 minutes long
 
-Ending credits will be detected if they are shorter than 4 minutes.
+## [Detection types](https://github.com/intro-skipper/intro-skipper/wiki#detection-types)
 
-These parameters can be configured by opening the plugin settings
+## [Installation](https://github.com/intro-skipper/intro-skipper/wiki/Installation)
 
-## Installation
+## [Jellyfin Skip Options](https://github.com/intro-skipper/intro-skipper/wiki/Jellyfin-Skip-Options)
 
-### Step 1: Install the plugin
+## [Troubleshooting](https://github.com/intro-skipper/intro-skipper/wiki/Troubleshooting)
-1. Add this plugin repository to your server: `https://raw.githubusercontent.com/jumoog/intro-skipper/master/manifest.json`
-2. Install the Intro Skipper plugin from the General section
-3. Restart Jellyfin
-### Step 2: Configure the plugin
-4. OPTIONAL: Enable automatic skipping or skip button
-    1. Go to Dashboard -> Plugins -> Intro Skipper
-    2. Check "Automatically skip intros" or "Show skip intro button" and click Save
-5. Go to Dashboard -> Scheduled Tasks -> Analyze Episodes and click the play button
-6. After a season has completed analyzing, play some episodes from it and observe the results
-    1. Status updates are logged before analyzing each season of a show
 
-## Troubleshooting
+## [API Documentation](https://github.com/intro-skipper/intro-skipper/blob/master/docs/api.md)
-#### Scheduled tasks fail instantly
-- Verify that Intro Skipper can detect ffmpeg with Chromaprint
-    - Dashboard -> Plugins -> Intro Skipper -> Support Bundle Info
-- Verify that ffmpeg is installed and detected by jellyfin
-    - Dashboard -> Playback -> FFmpeg path
-- Verify that Chromaprint is enabled in ffmpeg (`--enable-chromaprint`)
 
-#### Skip button is not visible
+<br />
-- Verify you have successfully completed the scheduled task at least once
+<p align="center">
-- Clear your browser cache and reload the Jellyfin server webpage
+  <a href="https://discord.gg/AYZ7RJ3BuA"><img src="https://invidget.switchblade.xyz/AYZ7RJ3BuA"></a>
-- Fix any permission mismatches between the web folder and Jellyfin server
+</p>
-
-    * <b>Docker -</b> the container is being run as a non-root user while having been built as a root user, causing the web files to be owned by root. To solve this, you can remove any lines like `User: 1000:1000`, `GUID:`, `PID:`, etc. from the jellyfin docker compose file.
-
-    * <b>Install from distro repositories -</b> the jellyfin-server will execute as `jellyfin` user while the web files will be owned by `root`, `www-data`, etc. This can <i>likely</i> be fixed by adding the `jellyfin` user (or whichever user executes the jellyfin server) to the same group that owns the jellyfin-web folders. **You should only do this if they are owned by a group other than root**.
-
-## Installation (MacOS)
-
-1. Build ffmpeg with chromaprint support using brew:
-    - macOS 12 or newer can install the [portable jellyfin-ffmpeg](https://github.com/jellyfin/jellyfin-ffmpeg)
-
-```
-brew uninstall --force --ignore-dependencies ffmpeg
-brew install chromaprint amiaopensource/amiaos/decklinksdk
-brew tap homebrew-ffmpeg/ffmpeg
-brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-chromaprint
-brew link --overwrite ffmpeg
-```
-
-2. Open ~/.config/jellyfin/encoding.xml and add or edit the following lines
-    - Replace [FFMPEG_PATH] with the path returned by `whereis ffmpeg`
-
-```
-<EncoderAppPath>[FFMPEG_PATH]</EncoderAppPath>
-<EncoderAppPathDisplay>[FFMPEG_PATH]</EncoderAppPathDisplay>
-```
-
-4. Follow the [general installation instructions](#installation) above
