Coding at the command line with Vim!
====================================

# Why Vim?
- Runs everywhere (your server), bindings in all your IDEs.
- Very effective for most dynamic / scripting languages and others
  that operate closely on the command line.
- The genius of modal editing. Normal vs Insert vs Visual vs Visual Blocks
