Beyond helping 18F staff do their best work, we hope these guides will inspire other federal agencies to adopt new practices. 18F’s projects with other federal agencies show that these techniques can help projects stay within budget, provide excellent value to the public, and fulfill federal rules.

These guides, and all of 18F’s work, are in the worldwide public domain. You are free to copy and adapt them as you choose. If you see something amiss or want to suggest a change, there are links at the bottom of each guide to help you contribute.
