Which means that either:<ul><li>The author must hold the copyright in all of the material themselves</li><li>The material must be licensed under a license compatible with <a class="tc-tiddlylink tc-tiddlylink-resolves" href="https://tiddlywiki.com/static/TiddlyWiki.html">TiddlyWiki</a>'s BSD license</li></ul></li><li>The author must sign the Contributors License Agreement (see below)</li><li>Each PR should only make a single feature change</li><li>The title of the PR should be 50 characters or less</li><li>The title of the PR should be capitalised, and should not end with a period</li><li>The title of the PR should be written in the imperative mood. See below</li><li>Adequate explanation in the body of the PR for the motivation and implementation of the change.

See <a class="tc-tiddlylink-external" href="https://chris.beams.io/posts/git-commit/#imperative" rel="noopener noreferrer" target="_blank">this post</a> for more details, but the gist is that the title of the PR should make sense when used to complete the sentence &quot;If applied, this commit will...&quot;. So for example, these are good PR titles:</p><ul><li>If applied, this commit will <em>update the contributing guidelines</em></li><li>If applied, this commit will <em>change css-escape-polyfill to a $tw.utils method</em></li><li>If applied, this commit will <em>make it easier to subclass the wikitext parser with a custom rule set</em></li></ul><p>These a poorly worded PR titles:</p><ul><li><strike>If applied, this commit will <em>edit text widgets should use default text for missing fields</em></strike></li><li><strike>If applied, this commit will <em>signing the CLA</em></strike></li><li><strike>If applied, this commit will <em>don't crash if options.event is missing</em></strike></li></ul><p>PR titles may also include a short prefix to indicate the subsystem to which they apply. For example:</p><ul><li><em>Menu plugin: Include menu text in aerial rotator</em></li></ul><h1 class="">Commenting on Pull Requests</h1><p>One of the principles of open source is that many pairs of eyes on the code can improve quality.
