-Detection of Protein Symmetry  and Pseudo-symmetry using BioJava
+Protein Symmetry using BioJava
 ================================================================
 
-This chapter is still under construction. See the [protein symmetry](https://github.com/rcsb/symmetry) project for more information for now.
+BioJava can be used to detect, analyze, and visualize **symmetry** and 
+**pseudo-symmetry** in the quaternary (biological assembly) and tertiary 
+(internal) structural levels.
+
+## Quaternary Symmetry
 
-BioJava can be used to
- - Detect, analyze, and visualize **protein symmetry**
- - Detect symmetry in **biological assemblies**

- - Detect **internal pseudo-symmetry** in protein chains

+
+## Internal Symmetry
+
+**Internal symmetry** refers to the symmetry present in a single chain, that is, 
+the tertiary structure. The algorithm implemented in biojava to detect internal 
+symmetry is called **CE-Symm**.
