 ## Purpose
 Atom Architect is a VASP visualization and structure building tool. Its unique
 feature is that atom placement is conducted in a relative fashion, i.e. with
 respect to the existing atomic structure. This is especially useful for
 catalysis purposes where atoms are typically placed at e.g. bridge, threefold or
 fourfold sites.
 
+## Features
+
+* Construction of VASP POSCAR files.
+* Analysis of geometry optimization, frequency analysis and nudged elastic band
+  calculations.
