The Drupal community is having a Global Sprint Weekend on the weekend of 17-18 January, 2015. You can join a local sprint in your area, or participate remotely via IRC.
Either way, the Documentation Working Group would like to invite both new and experienced Drupalists to participate in our the Drupal 8 Help Review sprint during this weekend (or at any time)!
Really, anyone can do this! The task is basically to do a (hopefully final) review of the Help topics that are provided by the Drupal 8 Core modules on their Help pages (the pages you see on admin/help within a Drupal site, which are produced by hook_help() functions within the module code). You do not need to be an expert writer, a Drupal expert, or an expert at anything else to help out -- all you need is a few minutes when you're in the mood to read a short page carefully and critically to see if it's accurate.
There are detailed instructions on how to review a topic on the issue: https://www.drupal.org/node/2283477
These reviews can be done at any time, not only during the sprint weekend -- and each one should just take maybe 15 or 20 minutes at the most, so if you have a few minutes, feel free to jump in and help out!
We suggest that people who are reviewing help topics during the Global Sprint weekend use the #drupal-docs IRC channel to collaborate. For instance, you might type in there "I'm reviewing help on https://www.drupal.org/node/2283477 and I'm going to start on the Search module", or ask questions if you are not sure whether something you find in a help topic is OK or not. If the #drupal-docs channel is not active, you can also try the #drupal-contribute to get your questions answered. People usually have opinions there, but there may be a lot of non-documentation things going on in that channel. And if you don't know about IRC, read: https://www.drupal.org/irc
Happy sprinting -- let's get this help text reviewed and updated!
