 Treadle and FIRRTL Interpreter
 ==============================
 
-`Treadle <https://github.com/freechipsproject/treadle>`__ and `FIRRTL Interpreter <https://github.com/freechipsproject/firrtl-interpreter>`__
+`Treadle <https://github.com/freechipsproject/treadle>`__ and
+`FIRRTL Interpreter <https://github.com/freechipsproject/firrtl-interpreter>`__
 are circuit simulators that directly execute FIRRTL (specifically low-firrtl IR).
-They are especially useful for interactive debugging and many of projects within Chipyard
-use them for a low-overhead simulator.
+Treadle is the replacement for FIRRTL Interpreter but FIRRTL Interpreter is still used within some
+projects. Treadle is useful for simulating modules in a larger SoC design. Many projects
+use Treadle for interactive debugging and a low-overhead simulator.
