High Voltage vs MkDocs: What are the differences?
Developers describe High Voltage as "Easily include static pages in your Rails app". Write your static pages and put them in the RAILS_ROOT/app/views/pages directory. On the other hand, MkDocs is detailed as "*A static site generator *". It builds completely static HTML sites that you can host on GitHub pages, Amazon S3, or anywhere else you choose. There's a stack of good looking themes available. The built-in dev-server allows you to preview your documentation as you're writing it. It will even auto-reload and refresh your browser whenever you save your changes.
High Voltage and MkDocs can be categorized as "Static Site Generators" tools.
