 ## Installation
 
 1. Find the Postgres client shared library on your system. The file name is libpq.so and it should be in /usr/lib or /usr/local/lib.
 
-2. Set the enviroment variable POSTGRES_LIB to reference the ***full path*** to the Postgres shared library (this is only needed during installation. Once initialized, GCfP remembers where this library is located).

+## Quick Getting Started
+
+### Getting a connection to Posgres
+1. First get an instance of GsPostgresConnectionParameters and intialize it to connect to your Postgres database. For example:
+```
+| params |
+params := (GsPostgresConnectionParameters new)
+		host: 'localhost';
+		port: 5432;
+		dbname: 'MyPostgresDb';
+		connect_timeout: 10;
+		yourself .
+```
+
+2. Now get an instance of GsPostgresConnection using the parameters object from step 1:
+```
+| connection |
+connection := GsPostgresConnection
+				newWithParameters: params.
+```
+
+3. Now you have an active connection to Postgres. You can use it to execute queries on Postgres which return a GsPostgresReadStream
+object, or execute insert, update, or delete operations on rows in Postgres.

 ## Running the Unit Tests
 
 To run the unit tests, you first need to create a writable Postgres database. Use the createdb Postgres command to create database:
