+
+## Why created
+
+awscli is by far the most comprehensive CLI tool manupulating various AWS services, and I really like its flexible options and up-to-date release cycle. However, day-to-day AWS operations from my terminal don't need that much flexibility and that many services. Rather, I wanted just small set of UNIX-like commands which are easy to use and remember.
