 # PDB ligand environment component
 
-This is a web-component to display ligand structure in 2D along with its interactions. Ligand can be perceived as a set of covalently linked pdb residues (refered to as bound molecule) or a single pdb residue. This depiction can be enriched with a substructure highlight and binding site interactions.
