 # ORCΛ
 
-Orca is an [esoteric programming language](https://en.wikipedia.org/wiki/Esoteric_programming_language) designed to quickly create procedural sequencers, in which every letter of the alphabet is an operation, where lowercase letters operate on bang, uppercase letters operate each frame.
+Orca is an [esoteric programming language](https://en.wikipedia.org/wiki/Esoteric_programming_language) and live editor designed to quickly create procedural sequencers. Every letter of the alphabet is an operation, lowercase letters execute on `*bang*`, and uppercase letters execute each frame.
 
-This application **is not a synthesizer, but a flexible livecoding environment** capable of sending MIDI, OSC & UDP to your audio/visual interfaces, like Ableton, Renoise, VCV Rack or SuperCollider.
+This is the C implementation of the [ORCΛ](https://wiki.xxiivv.com/site/orca.html) language and terminal livecoding environment. It's designed to be power efficient. It can handle large files, even if your terminal is small.
