 Pyda lets you write simple *dynamic* binary analysis tools using Python.
 
-Pyda injects a CPython interpreter ***in the same process as the target***. This means
-your Python code can directly manipulate memory in the target process, without going through ptrace.
+Pyda combines [Dynamorio](https://dynamorio.org)-based instrumentation with a CPython interpreter, allowing you to ***write hooks
+in Python*** that can manipulate memory/registers in the target, without going through ptrace. The interpreter runs in the same
+process as the target, resulting in a faster and more pleasant development experience vs. GDB.
 
 It is intended to fufill many of the same use-cases as debuggers (e.g. GDB/Pwndbg),
 or complex dynamic instrumentation frameworks (Frida, Dynamorio, DynInst, PIN, etc.).
