Getting started

Install:

$ npm install -g @geut/chan

Usage

Create a CHANGELOG.md file in your project root folder with:

$ chan init

To add entries to your CHANGELOG use the command that describes better your change (added, changed, fixed, etc)

$ chan added "New feature in my API to print foo in the console."

This command will modify your CHANGELOG creating a new entry called added under the Unreleased section.

chan follows the keepachangelog.com format/style.

Release your changes:

$ chan release 0.0.1

And you will get something like:

# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
