No. The manual is a PDF file and you cannot modify the content. This allows us to keep the content in the manual up-to-date.
Note: I am currently looking into offering an 'Elite' membership option for a very limited number of customers where I would make all the manual's source files available with full PLR and provide exclusive monthly lead generation content that WordPress website developers can use to generate more leads and clients for their services. More information about the proposed 'Elite' Membership option is available here.
You can purchase the manual now, register your interest in becoming an 'Elite' member and upgrade later if this option becomes available.
