Indeed you have done a very nice job on these documents! With one glaring exception: you say in a couple of places in …/installing_tools_windows “At the time of this writing,…”, yet nowhere in the document do you say when that is. While this is a common failing in many McNeel documents, it is certainly contrary to commonly accepted documentation practice. I have been using Rhino and it’s documentation throughout it’s history and I have seen many documents become stale and out of date, but they hang on unrevised, sometimes for quite a while, until some major housecleaning finally updates or deletes them. Regardless of intentions when they are written, this is just a fact of life. Having the date of last revision on the document in a reasonably prominent place goes a long way toward helping the reader understand what he’s looking at while the document slowly collects dust.
Anyone with experience with documentation associated with serious, mainstream technology from professional companies will have seen the various ways this issue is handled. For example: military equipment, aviation, government regulations, mainstream software companies like IBM, HP, SGI, just to name a few.
