git clone https://github.com/alexgenaud/buddhadust.git
The nightly zip archives are likely the latest versions of the BuddhaDust content. Nightly zip archives may contain the full site, sans EPUB, PDF, and ZIP (ex buddhadust-19801.zip) or may contain only the latest text/HTML with no resources, not even images (ex buddhadust-no-resources-19728.zip) or may contain only e-pub, pdf, or zip (with obvious names). Below are the latest nightly archives.
