 - The `amino3to1` method of `biopandas.pdb.PandasPDB` objects now returns a pandas `DataFrame` instead of a pandas `Series` object. The returned data frame has two columns, `'chain_id'` and `'residue_name'`, where the former contains the chain ID of the amino acid and the latter contains the 1-letter amino acid code, respectively.
 -  Significant speed improvements of the `distance` method of both `PandasPdb` and `PandasMol2` (now about 300 percent faster than previously).

+# Summary
+
+BioPandas is a Python library that reads molecular structures from 3D-coordinate files, such as PDB (Bernstein *and others* 1977) and MOL2, into pandas DataFrames (McKinney 2010) for convenient data analysis and data mining related tasks.
+
+In addition to parsing protein and small molecule data into a data frame format, BioPandas provides additional utility functions for structure analysis. These functions include common computations such as computing the root-mean-squared-deviation between structures and converting protein structures into primary amino acid sequence formats. 
+
+Furthermore, useful small-molecule related functions are provided for reading and parsing millions of small molecule structures (from multi-MOL2 files) fast and efficiently in virtual screening applications. Inbuilt functions for filtering molecules by the presence of functional groups and their pair-wise distances to each other make BioPandas a particularly attractive utility library for virtual screening and protein-ligand docking applications.
