+[![Build status](https://ci.appveyor.com/api/projects/status/7kedayu8diw41day?svg=true)](https://ci.appveyor.com/project/rudolfsonjunior/node-semantic-git-release-cli)
+[![Coverage Status](https://coveralls.io/repos/github/aichbauer/node-semantic-git-release-cli/badge.svg?branch=master)](https://coveralls.io/github/aichbauer/node-semantic-git-release-cli?branch=master)
+
+> A CLI for semantic releases. Writes a changelog and tags the new version.
+
+<img src="https://raw.githubusercontent.com/aichbauer/node-semantic-git-release-cli/master/media/screenshot.gif">
+
+## Why?
+
+Many projects need versioning. It is always the same: testing, writing the changelog, updating the version, tagging the commit, and finally releasing the new version.
+
+`sgr` will take care of all of them, so you can focus on the more important stuff: **code**
+
+## Installation
+
+```sh
+$ npm i -g semantic-git-release-cli
+```
+
+or
+
+```sh
+$ yarn add global semantic-git-release-cli
+```
+
+## Usage
+
+Forget the times when you had to manually write changelogs, update versions, tag commits. Now just type:
+
+```sh
+$ sgr
+```
+
+or if you already have an alias for sgr, use following instead:
+
+```sh
+$ semantic-git-release
+```
+
+## Tasks
+
+So there are a few tasks `semantic-git-release-cli` will do for you:
+
+- removes and reinstalls `node_modules` (prefers `yarn` by default)
+- runs tests by calling `npm test`
+- updates the `version` in `package.json`
+- creates or updates the `CHANGELOG.md`
+- commits and tags the new `version`
