QIIME™ has been succeeded by QIIME 2

As of 1 January 2018, QIIME 2 has succeeded QIIME 1. Refer to https://qiime2.org to learn how to install and start using QIIME 2.

QIIME 1 is no longer officially supported; development and support efforts are focused entirely on QIIME 2. Background on the transition is here.

If you're just getting started with QIIME, you should learn QIIME 2, not QIIME 1. QIIME 1 is outdated, and QIIME 2 contains many improvements to analytic functionality, is easier to install, and is easier to use.
