+# dpq - A D PostgreSQL library
+
+dpq wraps the libpq library and aims to provide a simple and modern way to access PostgreSQL in the D programming language.
+
+Very incomplete for now.
+
+## Current features:
+ - Opening a connection using a connection string
+ - Queries
+ - Fetching the results of queries in binary format
+  
+ ## Planned features
+ - Object-relational mapping
+ - Automatic schema creating from objects
+ - Connection pooling
+ - a Query object of some kind to simplify querying
+ - foreach looping through results
+ - Errors messages and exceptions :)
+ 
+ ## Documentation
+There is no docs yet, in the future, they should be written into the source code itself.
+ 
+## Some notes:
+ - If a wrong type is specified while fetching a column, the results are undefined. Most likely just garbage
+ - Errors on connecting throw an exception, other errors don't (yet)
+ - Fetching result data is only possible via indexes for now (using `Connection.get(int row, int col)`)
+
+## Licence
+MIT, read LICENSE.txt
+
+## Very simple example code
+
+```d
+import std.stdio;
+
+import dpq.connection;
+
+import std.stdio;
+
+void main()
+{
+	writeln("Connecting");
+	auto conn = SQLConnection("host=10.2.0.2 dbname=testdb user=testuser password='VerySecureTestPassword'");
+	writefln("Error message from connection: \"%s\"", conn.errorMessage);
+	writeln("Connected");
+	writefln("Database name is: %s.", conn.db);
+	writefln("Current user is: %s.", conn.user);
+
+	writeln("Sending a query");
+	auto res = conn.execParams("SELECT $1::int, $2::text", 1, "asd");
+	writeln("Sent a query");
+	writefln("Error message from connection: \"%s\"", conn.errorMessage);
+
+	writefln("Query result rows: %d.", res.rows);
+	writefln("Query result columns: %d.", res.columns);
+
+	writefln("result.get(0, 0) is: %d", res.get!int(0, 0));
+	writefln("result.get(0, 2) is: %s", res.get!string(0, 1));
+}
+
+```
