 # Brion
 
+![](doc/BBPLOGO350.jpg)
+
 Welcome to Brion, a C++ library for read and write access to Blue Brain data
 structures, including BlueConfig/CircuitConfig, Circuit, CompartmentReport,
 Mesh, Morphology, Synapse and Target files.
 
+Brion can be retrieved by cloning the
+[source code](https://github.com/BlueBrain/Brion.git).
+
 ## Features
 
-Brion provides the following functionality:
-* Fast and low-overhead access to read and write BBP data
-* Basic data types to work with the loaded data using vmmlib, Lunchbox, Boost
+Brion provides the following major features:
 
-## Downloads
+* Fast and low-overhead read access to:
+  * Blue configs (brion::BlueConfig)
+  * Circuit description (brion::Circuit)
+  * H5 Synapses data (brion::SynapseSummary, brion::Synapse)
+  * Target (brion::Target)
+  * BBP binary meshes (brion::Mesh)
+  * BBP H5 morphologies and SWC morphologies (brion::Morphology)
+  * Compartment reports (brion::CompartmentReport)
+  * Spike reports (brion::SpikeReport)
+* Fast and low-overhead write access to:
+  * Compartment reports (brion::CompartmentReport)
+  * BBP binary meshes (brion::Mesh)
+  * BBP H5 morphologies (brion::Morphology)
+* Basic [data types](@ref brion/types.h) to work with the loaded data using
+  [vmmlib](http://vmml.github.io/vmmlib),
+  [Lunchbox](http://eyescale.github.io/Lunchbox-1.8/index.html),

 * Morphology class implementation changed to support the Lunchbox plugin
   mechanism.
+* New morphology plugin to read SWC morphologies.
+* [#3](https://github.com/BlueBrain/Brion/pull/3):
+  New morphology converter tool.
+* New null compartment report for benchmarks.
+* New spike converter tool.
+* Optimized function Circuit::get for large circuits (cut down the loading time
+  of the 3.1 M neuron circuit by 6.5 seconds in a Core i7-4930K @ 3.40GHz).
+* Replace use of iostreams by lunchbox::MemoryMap.
+* Several bugfixes and cleanups.
