Note that there is a difference between project documentation and the +<a href="https://tinkerpop.apache.org/";>TinkerPop web site</a>. The project documentation refers to the documentation that is +published per release like, tutorials, reference documentation, and other similar pages. This content is not updated +after release and remains static bound to that version. The TinkerPop web site refers to the static home page and its +related content, such as <a href="https://tinkerpop.apache.org/gremlin.html";>Understanding Gremlin</a>, +<a href="https://tinkerpop.apache.org/policy.html";>Provider Listing and Graphic Usage Policies</a> and other similar pages. +This content is not bound to any particular version and can be published at any time where new content simply replaces +old content.</p> +</div> +<div class="paragraph"> +<p>For both types of documentation, changes can be submitted via pull request. For project documentation, TinkerPop has +a robust documentation system that is based on <a href="http://asciidoc.org/";>asciidoc</a>. The content can be found in the +<a href="https://github.com/apache/tinkerpop/tree/master/docs/src";>docs/src</a>. Documentation is version specific, so consider +the appropriate branch on which to submit the pull request so that the documentation is reflective of the version it is +tied to. To view generated documentation locally, read more about environment configurations in the +<a href="#documentation-environment">Documentation Environment</a> and <a href="#documentation">Contributor Documentation</a> sections.</p> +</div> +<div class="paragraph"> +<p>For web site changes, the process is largely the same except that the documentation system is HTML based instead of +Asciidoc. The content can be found in the source control tree at <a href="https://github.com/apache/tinkerpop/tree/master/docs/site";>docs/site</a>. +The web site is always published from the <code>master</code> branch as it is not bound to a version, so there is no need to +submit a pull request to any other branches besides that one. If the change to this documentation involves changing +provider listings in some way, first propose those changes on the <a href="mailto:[email protected]";>[email protected]</a> mailing list and achieve +consensus (wait time is 72 hours as usual). At that point, pull requests or direct changes can be submitted. +Again, see the <a href="#documentation-environment">Documentation Environment</a> section for more information on how to generate +the site locally.</p> +</div> +</div> +<div class="sect2"> +<h3 id="_reporting_bugs">Reporting Bugs</h3> +<div class="paragraph"> +<p>Well formed bug reports (especially when accompanied by a pull request that fixes the problem) are welcome +contributions that ultimately help improve the quality of TinkerPop. Of course, a bug report is only as good as its +reproduction steps and the surrounding details of the issue. When a bug is encountered, it should be documented in +<a href="https://issues.apache.org/jira/browse/TINKERPOP";>JIRA</a>, where it will likely trigger some discussion and +ultimately a resolution.</p> +</div> +</div> +<div class="sect2"> +<h3 id="_tinkerpop_libraries">TinkerPop Libraries</h3> +<div class="paragraph"> +<p>TinkerPop is more than just the core source code repository.

As such, large and independent new functionality is often rejected from inclusion in TinkerPop +itself, however, it is very much encouraged that such a project stand on its own as separate repository. Projects like +this that meet the TinkerPop <a href="https://tinkerpop.apache.org/policy.html";>listing policy</a> can be added to the +TinkerPop web site and promoted there. Please see the current listing of such libraries on the TinkerPop +<a href="https://tinkerpop.apache.org/#graph-systems";>home page</a> to get an idea as to what kinds of libraries are available +from the community.
