+# Video to Minecraft
+This plugin is meant to read video files and allow you to watch it in minecraft using ffmpeg *(no audio)*
+
+# Commands
+* `/watch <video>` - This command searches for a video in the plugin's data folder (`plugins/VideoToMinecraft`) and plays it on a map item *(requires `videotominecraft.watch` permission)*
+* `/watchmovie <video>` - This command does the same as `/watch` however, it uses item frames and multiple maps to increase the resolution of your video *(requires `videotominecraft.watchmovie` permission)*
+
+# Known Issues
+
+* You have to be looking south to spawn a movie theatre correctly
+* The max extraction time is 120 seconds which can limit your
+
+# Next Steps
+* Better cache system
+* Resource pack server to host a templated pack with audio
