18F Open Source Style Guide

This guide helps people document code repositories so that they're easy to use and understand. In each section, we outline our strategies for making sure that our code repositories are clear, accessible, and user-friendly.

It’s important to make sure our documentation is clear both for internal and external audiences. As our team expands, we want our new employees to easily find and use our existing codebases.

It's also really important if we want to make outside contributors feel welcome or have outside organizations fork and use our code. (And we do!) Explaining what a project is, why it's important, and how people can help ensures that people can fork and adapt our projects.

(Fork means to copy the code that exists over to your own repo, or repository of code, so that you can adapt or use it as needed.)

This guide also contains a checklist we created that helps ensure our repos are clear, accessible, and user-friendly. Some terminology used may be GitHub-specific, but the concepts are applicable regardless of your version control system or platform. We wrote it so that both non-coders and coders can understand it. (If something is not clear, please let us know.)

We’re sharing it because it we think it’s helpful for lots of organizations, including our own. We know that many of our repos don’t conform to this exact style. By articulating a specific style, we hope this document will also help us improve our own practices.

How to use this guide

We created this guide for reference on an as-needed basis. It’s here when you’re wondering how to describe a repo, for instance, or when you’re wondering how to create a friendly, informational tone when writing issues for users.

To this end, we’ve structured the guide into descriptively named sections. Browse our table of contents to find the topic you’re looking for.

Most importantly, we encourage you to make a copy of this document and adapt it to your organizational needs. This guide is just that: a guide. It’s not meant to provide the final opinion on any of the topics discussed. If a certain section isn’t relevant to you and your team, delete it. And if you feel the guide is missing a section, by all means, add it by clicking 'edit this page' at the bottom of every page. This guide is yours to use, and we trust you’ll update it in the ways that best suit you.

How to run a local copy of this guide

(Instructions adapted from the 18F Documentation Working Group.)

You will need Ruby ( > version 2.1.5 ). You may consider using a Ruby version manager such as rbenv or rvm to help ensure that Ruby version upgrades don't mean all your gems will need to be rebuilt.

On OS X, you can use Homebrew to install Ruby in /usr/local/bin, which may require you to update your $PATH environment variable:

$ brew update
$ brew install ruby

To serve the site locally:

$ git clone
$ cd open-source-guide
$ ./go serve

This will check that your Ruby version is supported, install the Bundler gem if it is not yet installed, install all the gems needed by the template, and launch a running instance on http://localhost:4000/. (Make sure to include the trailing slash! The built-in Jekyll webserver doesn't redirect to it.)

After going through these steps, run ./go to see a list of available commands. The serve command is the most common for routine development.

How to create your own guide

This guide is based on the DOCter template created by the Consumer Financial Protection Bureau (CFPB). Our canonical adaptation of DOCter is contained in the 18F Guides Template.
