     <h1>Engineering Principles and Practices</h1>

 <p>This document is an attempt to capture a shared set of values for the project.
 Many companies rely on Mesos as a foundational layer of their software
 infrastructure and it is imperative that we ship <strong>robust, high quality</strong>
 code. We aim to foster a culture where we can trust and rely upon the work of
 the community.</p>

 <p>The following are some of the aspirational principles and practices that
 guide us:</p>

 <ol>
 <li>We value <strong>craftsmanship</strong>: code should be easy to read and understand,
 should be written with high attention to detail, and should be consistent
 in its style. Code is written for humans to read and maintain!</li>
 <li>We value <strong>resiliency</strong>: our system must be highly-available, stable, and
 backwards-compatible. We must consider the implications of failures.</li>
 <li>We value <strong>accountability</strong>: we own and support our software, and are
 accountable for improving it, fixing issues, and learning from our mistakes.</li>
 <li>We value <strong>design and code review</strong>: review helps us maintain a high
 quality system architecture and high quality code, it also helps us mentor
 new contributors, learn to collaborate more effectively, and reduce the
 amount of mistakes.</li>
 <li>We value <strong>automated testing</strong>: automated testing allows us to iterate and
 refactor in our large codebase, while verifying correctness and preventing
 regression.</li>
 <li>We value <strong>benchmarking</strong>: benchmarking allows us to identify the right
 locations to target performance improvements. It also allows us to iterate
 and refactor in our large codebase, while observing the performance
 implications.</li>
 </ol>
