This document provides instructions on how to create communities in Salesforce. It begins by defining what a Salesforce community is - an interactive group that enables communication between a business and external individuals like customers or partners, as well as between employees. It then describes how to enable communities by navigating to Setup > Build > Customize > Communities > Settings and selecting "Enable Communities". Once enabled, communities can be created by navigating to Setup > Build > Customize > Communities > Manage Communities > New Communities and filling out the name, description, and URL. Created communities can then be managed through various settings like members, tabs & pages, branding, login page, emails, and miscellaneous options.
