Contributors do the real work around here by writing, testing and maintaining documentation. On this wiki "Documentation" does not just mean the manuals, it also includes articles on all sorts of topics that are important for a LibreCAD user. Simple concepts such as file saving, splines, the coordinate system and even Qt4 are important to document because they affect the way that people think about them and therefore use LibreCAD.
If you are interested in becoming a contributor please start contributing. There are no special requirements to begin contributing to the LibreCAD Wiki (although account creation is strongly encouraged). The process is painless and fun. Whether you are a beginner or a long-time CAD professional, we need your input!
You may wonder - "but what does a CAD beginner have to offer a serious engineering software project like LibreCAD?" Well, consider, that you are the one who has the "beginners' eyes", which means that you are the one for whom the documentation is of the upmost importance. If an article does not make sense to you or perhaps it contains specific topics which have not been laid out in enough sufficient detail (or not covered at all) because "old experienced CAD users" never thought of the need to document them, then for beginners it will make it much more difficult to grasp the fundamentals properly.
Without beginner input we can never know about these things, no matter how basic they may seem to you! And if we don't know that we need to address them - you cannot learn properly from the documentation. Beginner input is the most critical factor in developing a complete set of topic articles to compliment the main program documentation and Users' Guide for LibreCAD.
