+- For extraction of compiled languages on all platforms, the system must be configured so that it can successfully build and compile your code, independently of CodeQL.
+- On Linux, extraction of compiled languages (C/C++, C#, Go, Java) and Ruby requires ``glibc`` version 2.17 or greater.
+    - Extraction of these languages on ``musl-c``-based Linux distributions, such as Alpine Linux, is not supported.
+- TypeScript extraction on all platforms requires Node.js to be installed and available on the ``PATH`` as ``node``.
+- On Linux and macOS, extraction of Python 2 or Python 3 requires Python 3 to be installed and available on the ``PATH`` as ``python3`` or ``python``.
+        - For Python 2 extraction, we also recommend having Python 2 installed and available on the ``PATH`` as ``python2``.
+- On Windows, extraction of Python 2 or Python 3 requires the Python launcher to be installed and available on the ``PATH`` as ``py.exe``.
