+#
+# NOTE: 'pip-compile' only adds dependencies relevant for the Python version,
+# in which it is executed. Moreover, it does not add environment markers of
+# transitive dependencies.
+# The official recommendation for cross-environment usage of pip-compile tends
+# towards separate requirements files for each environment (see
+# jazzband/pip-tools#651), this seem like an overkill for tuf, where we only
+# have a few conditional dependencies, i.e. dependencies that are required on
+# Python < 3 only.
+#
+#
+# Below instructions can be used to re-generate 'requirements-pinned.txt', e.g.
+# if:
+# - requirements are added or removed from this file
+# - Python version support is changed
+# - CI/CD build breaks due to updates (e.g. transitive dependency conflicts)
+#
+# 1. Use this script to create a pinned requirements file for each Python
+#    version
+# ```
+# for v in 2.7 3.5 3.6 3.7 3.8; do
+#   mkvirtualenv tuf-env-${v} -p python${v};
+#   pip install pip-tools;
+#   pip-compile --no-header -o requirements-${v}.txt requirements.txt;
+#   deactivate;
+#   rmvirtualenv tuf-env-${v};
+# done;
+#
+# ```
+# 2. Use this command to merge per-version files
+#    `sort -o requirements-pinned.txt -u requirements-?.?.txt`
+# 2. Manually add environment markers to requirements-pinned.txt
+# 3. Use this command to remove per-version files
+#    `rm requirements-?.?.txt`
