+/*
+This (very The Lounge-custom) script is a helper to generate changelog entries.
+
+Note that it is not meant to produce fully-automated changelogs like other tools
+do, but merely prepare a changelog entry without risks of mistyping a URL or
+missing a contribution: changelogs are meant for humans, and therefore must be
+manually curated as such, with ❤️.
+
+## Set up:
+
+- Create a personal access token with `public_repo` at
+  https://github.com/settings/tokens. Make sure to write it down as you will not
+  be able to display it again.
+
+- Use Node.js v8+:
+
+  ```sh
+  nvm install 8
+  ```
+
+## Usage
+
+npm v5 removes packages not listed in package.json when running `npm install` so
+it is very likely you will have to run all those each time:
+
+```sh
+ export CHANGELOG_TOKEN=<The personal access token created on GitHub above>
+node scripts/changelog <version>
+```
+
+`<version>` must *not* be prefixed with `v`. It is formatted either:
+
+- `MAJOR.MINOR.PATCH` for a stable release, for example `2.5.0`
+- `MAJOR.MINOR.PATCH-(pre|rc).N` for a pre-release, for example `2.5.0-rc.1`
+
+## TODOs:
+
+- Use better labels for better categorization
+- Add some stats to the git commit (how many LOCs total / in this release, etc.)
+- This script requires Node v8, but `npm version` currently fails with Node v8
+  as we gitignore package-lock.json (how is that even a thing?!).
