 # Trinity
+
+Trinity is a simulation testing library for the Elixir programming language.
+
+Processes are deterministically scheduled within a given simulation, and only one process is allowed to execute at a time.
+Scheduling is done entirely in "user-space"; there are no modifications to the runtime (BEAM) itself.
+Trinity reimplements a number of OTP primitives in order to guarantee deterministic execution,
+and a simulated (in-memory) filesystem is also provided.
+
+## Status
+
+Trinity is experimental and under active development.
+Documentation and an eventual release are planned.
