Hi Sorry for being dense, but I can't seem to get ri to work either with the one-click Ruby installer for Windows (after fixing the path in ri.bat) or with the MSwin32 binaries. I have found other threads about this, and I've tried to run rdoc, but it looks like I need the Ruby source to do that. That's where things fall apart for me: which additional files do I need to download, where do I run rdoc, which command-line options to use, etc. Would somebody mind pointing me to (or walking me through) the steps I need to follow to get ri working properly? Thanks very much. (And thanks to those who have helped with my previous questions.) Steve
