What is Alfred? »
Alfred is many things. First, it's free application for OS X only, and it works as a program launcher, yet, if you upgrade to a Powerpack, then you have the ability to install Workflows.
What are Workflows? »
Workflows are like macros. Using hotkeys or keywords, Alfred will run a variety of scripts on your computer. These scripts can be written in most any language (Bash, Python, PHP, Ruby, Applescript, Go, and others). So, anything that those scripts can accomplish, Alfred can do for you in just a few keystrokes.
The Powerpack sounds great. Where can I get me one? »
Click this link. It costs money. It's worth it.
What is Packal? »
Packal is a dynamic repository for Alfred Workflows and Themes. Users can submit their own work for anyone to use. Themes are stored in an Alfred2-specific URI. Workflow files are pushed to Github, providing a level of redundant storage.
How do I submit my own Workflows or Themes? »
Thanks for the interest, but Packal is in the process of shutting down. Submit themes and workflows to the Alfred Gallery instead.
