+# Modbus Protocol for .NET | Common
+
+This package contains all basic tools to build your own clients.
+
+### Contracts
+
+**IModbusConnection**    
+This is the interface used on the base client to communicate with the remote device.
+If you want to use a custom connection type, you should implement this interface yourself.
+
+**IModbusProtocol**    
+If you want to speak a custom type of protocol with the clients, you can implement this interface.
+
+**ModbusBaseClient**    
+This abstract base client contains all the basic methods and handlings required to communicate via Modbus Protocol.
+The packages `AMWD.Protocols.Modbus.Serial`  _(in progress)_ and `AMWD.Protocols.Modbus.Tcp` have specific derived implementations to match the communication types.
+
+
+### Enums
+
+Here you have all typed enumerables defined by the Modbus Protocol.
+
+
+### Extensions
+
+To convert the Modbus specific types to usable values and vice-versa, there are some extensions.
+
+- Decimal extensions for `float` (single) and `double`
+- Signed extensions for signed integer values as `sbyte`, `short` (int16), `int` (int32) and `long` (int64)
+- Unsigned extensions for unsigned integer values as `byte`, `ushort` (uint16), `uint` (uint32) and `ulong` (uint64)
+- Some other extensions for `string` and `bool`
+
+
+### Models
+
+The different types handled by the Modbus Protocol.
+
+- Coil
+- Discrete Input
+- Holding Register
+- Input Register
+
+
+### Protocols
+
+Here you have the specific default implementations for the Modbus Protocol.
+
+- ASCII _(in progress)_
+- RTU _(in progress)_
+- TCP
