We recommend you disable documentation generation for gem install by default.
Note that Bundler won't install documentation Show archive.org snapshot , so this advice applies only when installing gems manually.

If you don't already have it, create a ~/.gemrc file. The gemrc is a Yaml file, so add the following line to add default switches to the gem command.

gem: --no-document

(If you do not know --no-document: it replaces the legacy switches --no-rdoc --no-ri. Its abbreviated version is -N.)
