+# NOTE: please check on new releases which steps aren't necessary anymore!
+# Currently the following things are done:
+#
+# * Add correct `name`/`version` field to `package.json`, otherwise `yarn2nix` fails to
+#   find required dependencies.
+# * Keep `tailwindcss` on version 2.0.1-compat (on `yarn` it will be upgraded due to the `^`).
+#   This is needed to make sure the entire build still works with `postcss-7` (needed
+#   by plausible).
+# * Adjust `file:`-dependencies a bit for the structure inside a Nix build.
+# * Update hashes for the tarball & the fixed-output drv with all `mix`-dependencies.
+# * Generate `yarn.lock` & `yarn.nix` in a temporary directory.
