 Exceptions and abstract classes containing logic for [PHP/SAP][phpsap] that is not specific to the underlying PHP module.
 
-## Exceptions
-
-The following exceptions are available in namespace `phpsap\exceptions`:
-
-* `SapException` a generic exception inherited by all other exception.
-* `ConfigKeyNotFoundException` in case a configuration key could not be found.
-* `ConnectionFailedException` in case a connection could not be established.
-* `UnknownFunctionException` in case the remote function doesn't exist.
-* `FunctionCallException` in case the remote function call failed.
-
-## Abstract classes
-
-The abstract classes define the logic of the PHP/SAP library, that is not specific to the underlying PHP module used to talk to SAP.
-
-These classes are available in namespace `phpsap\classes`:
-
-* `AbstractConfigContainer` A JSON encodeable configuration container implementing PSR-11 for retrieving configuration parameters.
-* `AbstractConfig` Configure basic connection parameters for SAP remote function calls, that are common to both connection types (A, and B)  implementing `\phpsap\interfaces\IConfig`.
-* `AbstractConfigA` Configure connection parameters for SAP remote function calls using a specific SAP application server (type A) implementing `\phpsap\interfaces\IConfigA`.
-* `AbstractConfigB` Configure connection parameters for SAP remote function calls using load balancing (type B) implementing `\phpsap\interfaces\IConfigB`.
-* `AbstractConnection` Manages a PHP/SAP connection instance implementing `\phpsap\interfaces\IConnection`.
-* `AbstractFunction` Manages a PHP/SAP remote function call implementing `\phpsap\interfaces\IFunction`.
-* `AbstractRemoteFunctionCall` Proxy class to simplify PHP/SAP remote function calls implementing `\phpsap\interfaces\IFunction`.
-* `ConnectionPool` Provides a static pool of available PHP/SAP connections. The connections are organized using their connection IDs. The connection ID ensures, that only one connection per configuration is established.
