Download The Plug-in
Thank you for your interest in PressBooks, the CMS for books. You can find the PressBooks WordPress plug-in below; hosted on GitHub.
Before you download, perhaps you'd like to consider supporting development of this free software with a donation:
NOTES: You will be redirected to GitHub after your donation. The PressBooks plugin should be installed with a FRESH install of WordPress Multisite, not an existing blog. You should also read the readme.txt file.
