+# Owncast Product Definition
+
+## Why
+
+By defining the goals and target user bases we have something stable to guide decisions, features, conversations and keep clarity around what is being built.
+
+While these definitions and lists should not be seen as exhaustive, in theory, once this is seen as "complete" there should be few, if any changes, as that would note a large change in direction and goals.
