 ## Requirements
 
 - Holoscan SDK 5.0.0 or later with CUDA 13
-- CMake 4.0 or later and a C++20-capable compiler
-- Python 3.12 through 3.14 for the `holoscan-cli==5.0.0` commands used by this walkthrough
+- CMake 4.0 or later and a C++20-capable compiler for Modules with C++ operators
+- Python 3.12 through 3.14 for the `holoscan-cli` commands used by these walkthroughs
 - Docker, Docker Buildx, and NVIDIA Container Toolkit for the recommended container workflow

+Module operators are implemented in C++ or Python. For C++ operators, the scaffold can add Python
+bindings so Python applications can use them, and the packaged artifact is a Debian package.
+From Holoscan CLI `5.1.0`, the bindings can also ship as a Python wheel, and
+`holoscan create --language python` creates a pure-Python Module that ships as a Python wheel and
+needs no C++ compiler.
 
-The examples use `holoscan-cli==5.0.0` from PyPI, the version pinned by the current SDK 5

+The examples install `holoscan-cli` from PyPI; each tutorial pins the CLI version it uses. CLI and
