> Readme Standard Style

This repo is for standardizing how READMEs should look. The goal is to have: 
  - A well defined specification that other people could look to;
  - An example README that can be used for comparison (this README.md is the example);
  - A linter that can be used to look at errors in a given Readme;
  - A generator that can be used to quickly scaffold out new READMEs.

## Background

Standard Readme started with in the issue originally posed by [@maxogden](https://github.com/maxogden) over at [feross/standard](https://github.com/feross/standard) in [this issue](https://github.com/feross/standard/issues/141). A lot of that discussion ended up in [zcei's standard-readme](https://github.com/zcei/standard-readme/issues/1) repository. While working on maintaining the [IPFS](https://github.com/ipfs) repositories, I needed a way to standardize Readmes. This is a result of that.

### Goals:
1. A well defined **specification**. This can be found in the [Specification](#specification) section. It is a constant work in progress; please open issues to discuss changes.
2. **An example README**. This Readme is fully standard-readme compliant.
3. A **linter** that can be used to look at errors in a given Readme. Please refer to the [tracking issue](https://github.com/RichardLitt/standard-readme/issues/5).
4. A **generator** that can be used to quickly scaffold out new READMEs. Please refer to the [tracking issue](https://github.com/RichardLitt/standard-readme/issues/6).
5. A **compliant badge** for users.

## Installation

This project uses [node][] and [npm][]. Go check them out if you don't have them locally installed.

```sh
$ npm i -g standard-readme

// Will output spec (this Readme)
```
