Documentation is something anyone can do with a spare 10 minutes:<br>
1) install git<br>
2) install xmlmind<br>
3) "fork" drools on github, <a class="moz-txt-link-freetext" href="https://github.com/droolsjbpm/drools">https://github.com/droolsjbpm/drools</a><br>
4) clone your fork locally<br>
5) make changes to files with xmlmind, or xml editor of choice<br>
<a class="moz-txt-link-freetext" href="https://github.com/droolsjbpm/drools/tree/master/drools-docs/drools-fusion-docs/src/main/docbook/en-US">https://github.com/droolsjbpm/drools/tree/master/drools-docs/drools-fusion-docs/src/main/docbook/en-US</a><br>
6) commit changes, push changes back to github<br>
7) use github gui to submit a pull request for your changes.<br>
<br>
It'll be more obvious to users what documentation is missing, and
they'll be able to word it better in a way that makes more sense to
other users.<br>
