+# PDB Utilities
+
+The PDB module provides utility functions to deal with [PDB (Protein Data Bank)](https://www.wwpdb.org/documentation/file-format) files by thinly wrapping [BioPython's PDB Parser](http://biopython.org/wiki/Main_Page).
+
+## Exported functions
+
+```julia get_structure(filename::String)```
+
+Parses a PDB file and returns a structure PyObject.
+
+```get_chains(structure::PyObject)```
+
+Gets the chains of protein structure from a BioPython PyObject and returns an Array of Array{Float64,2} matrices.
+
+```structure_to_matrix(structure::PyObject)```
+
+Converts a BioPython structure to a Array{Float64,2} matrix.
