 ## The Basics
 
-BioJava provides you with both a mmCIF parser and a data model that reads PDB and mmCIF files into a biological and chemically  meaningful data model (BioJava supports the [Chemical Components Dictionary](mmcif.md)). If you don't want to use that data model, you can still use BioJava's file parsers, and more on that later, let's start first with the most basic way of loading a protein structure.
+BioJava uses the [CIFTools-java](https://github.com/rcsb/ciftools-java) library to parse mmCIF. BioJava then has its own data model that reads PDB and mmCIF files

 ## First Steps
 
-The simplest way to load a PDB file is by using the [StructureIO](http://www.biojava.org/docs/api/org/biojava/nbio/structure/StructureIO.html) class.

+## Switching AtomCache to use different file types
 
-By default BioJava is using the PDB file format for parsing data. In order to switch it to use mmCIF, we can take control over the underlying [AtomCache](http://www.biojava.org/docs/api/org/biojava/nbio/structure/align/util/AtomCache.html) which manages your PDB ([and btw. also SCOP, CATH](externaldb.md)) installations.
