+# Appendix
+
+Here you may find conceptual content related to the exercises in the book.
+
+## qsv version
+
+qsv has multiple versions and may differ for each system. Here we run [a command](https://github.com/jqnatividad/qsv/blob/master/docs/PERFORMANCE.md#version-details) to show what version of qsv this book is using along with other information:
+
+```bash
+qsv --version
+```
+
+```{code-cell} python3
+:tags: [remove-input, scroll-output]
+
+result = !qsv --version
+print(result.n)
+
+```
+
+## qsv release assets
+
+A mapping of qsv release files for an arbitrary version X.Y.Z and platforms they may run on are shown in the table below.
+
+```{table} qsv release assets (vX.Y.Z)
