+## Next Generation OLTP Database Research
+## ---------------------------------------------------------------------------
 
-Thank you for your interest in VoltDB! The VoltDB project
-is managed at https://voltdb.com/.
+More information and documentation is available at:
 
-What is VoltDB?
-====================
-VoltDB is an in-memory online transaction processing (OLTP) database
-designed from the ground up to be the fastest most scalable OLTP
-system in the world.
+http://hstore.cs.brown.edu
 
+## ---------------------------------------------------------------------------
+## QUICK EXAMPLE
+## ---------------------------------------------------------------------------
 
-What it is not?
-===============
-VoltDB is not a general purpose database like MySQL or PostgreSQL, for
-example.
+(1) First build the entire distribution:
 
+    $ ant build
 
-Getting Started
-===============
-'ant check'      Compile VoltDB and run all tests.
+(2) Next make the project jar file for the target benchmark.
+    A project jar contains all the of stored procedures and statements for the target
+    benchmark, as well as the cluster configuration for the database system.
 
-'ant doc'        Generate Javadoc in doc/java-api:
+    $ export HSTORE_BENCHMARK=tm1
+    $ ant hstore-prepare -Dproject=$HSTORE_BENCHMARK
 
-'ant dist'       Create a .tar.gz distribution with example apps
-                 in obj/release/volt-version.tar.gz.
+(3) You can now execute the benchmark locally on your machine with two partitions
 
-There are three example projects which can be compiled and run.  See
-https://voltdb.com/svn/repos/build/newtrunk/examples/README for details.
+    $ ant hstore-benchmark -Dproject=$HSTORE_BENCHMARK
 
+More information is available here:
 
-Documentation
-=============
-doc/user_guide         Getting started using VoltDB.
-
-doc/developer_guide    Design overview and how to contribute.
-
-doc/developer_tools    Help using Eclipse, KDevelop, debugging...
-
-Additional documentation is available in SVN at:
-TODO: need documentation source.
-
-Design specifications are in SVN and are available online at:
-TODO: need documentation source.
