+## Why pyinstaller and not nuitka?
+
+I did have a bit experience in setting up pyinstaller. The size of the final executable seems to be [much smaller with pyinstaller](https://github.com/Nuitka/Nuitka/issues/926), too.
+
+## Why is the executable so large?
+
+Pandoc is included and is standalone ~144 MB large. This has the biggest impact on the size. The module sizes in particular can be analyzed by using the following code snippet in the pyinstaller spec file:
+
+```python
+coll = COLLECT(
+    exe,
+    a.binaries,
+    a.datas,
+    strip=False,
+    upx=True,
+    upx_exclude=[],
+    name='jimmy_cli',
+)
+```
+
+The resulting files can be listed and ordered by size by:
+
+```bash
+> du -lh dist/jimmy_cli | sort -h
+8,0K    dist/jimmy_cli/_internal/setuptools/_vendor/jaraco/text

+
+## Why cryptography and not pycryptodome?
+
+They worked both at the first implementation. `cryptography` made a slightly better impression, so it was chosen.
