+## Dependencies
+
+Ollie does **not** require [plan9port](https://9fans.github.io/plan9port/), either explicitly or implicitly. This was previously required by the runtime and is no longer true. Ollie includes its own Go 9P protocol implementation, clients, and namespace management. `olliesrv` creates its namespace directory and removes it only when empty.
+
+plan9port provides valuable additional tools and integrations, including Acme and general-purpose 9P utilities, but those are optional. The core Ollie runtime, `ollie-9p`, `toolsrv`, and native clients do not depend on plan9port or `$PLAN9`.
+
+The standard build requires Go 1.25+ and GNU Make. The optional KDE integration additionally requires CMake, Qt, and KDE Frameworks.
+
 ## Future work
