-# The intended way to store dependency info is that setup.py or pyproject.toml contains version
-# ranges, and requirements.txt contains specific versions in those ranges so that each deployment
-# gets the same dependencies from there.
-#
-# A downside is that if your deployment also gets dependencies from other places, they could specify
-# conflicting versions. This could be a problem for Porcupine: even though users usually install
-# Porcupine into a virtualenv that doesn't contain anything else, I don't want to assume that they
-# do.
-#
-# Another downside with pinning for Porcupine would be dependencies getting outdated easily.
-#
-# Solution: pin only the packages where updating will likely break things, and keep the same
-# dependencies in requirements.txt (for easy "pip install -r requirements.txt" during development)
-# and in pyproject.toml (for installing released versions).
+# Porcupine dependencies are specified in pyproject.toml, but also kept in
+# requirements-dev.txt for a convenient and familiar workflow. You just
+# "pip install -r requirements-dev.txt" when you start developing Porcupine.
