 # Dapper.FluentColumnMapping
 Fluent Object-Column Mappings for use with Dapper
+
+
+## How to use
+
+```c#
+// Create yourself a new mapping collection
+var mappings = new ColumnMappingCollection();
+
+// Start defining the mappings between each property/column for a type
+mappings.RegisterType<State>()
+        .MapProperty(x => x.Id).ToColumn("STATE_CD")
+        .MapProperty(x => x.Name).ToColumn("STATE_DESCRIPTION")
+        .MapProperty(x => x.Country).ToColumn("STATE_COUNTRY");
+
+// You can add multiple type mappings to a collection too
+mappings.RegisterType<UserActivityEvent>()
+        .MapProperty(x => x.EventId).ToColumn("ACTIVITY_ID")
+        .MapProperty(x => x.User.Id).ToColumn("USER_ID")
+        .MapProperty(x => x.ActivityDate).ToColumn("ACTIVITY_DATE")
+        .MapProperty(x => x.ActivityType).ToColumn("ACTIVITY_TYPE")
+        .MapProperty(x => x.Details).ToColumn("DETAILS");
+
+// Tell Dapper to use our custom mappings
+mappings.RegisterWithDapper();
+
+// Grab our data from the database
+IEnumerable<State> states;
+using (var dbConnection = CreateNewConnection())
+    states = dbConnection.Query<State>("SELECT * FROM STATES");
+
+```
