+For the online-mode of data assimilation, the numerical model has to be combined with PDAF into a single program to generate the assimilation system. This is done by adding several function calls into the model code.
 The implementation of PDAF with an existing model can be performed in a few steps. A possible sequence is the following:

 In Steps 1 to 3, PDAF is attached to the numerical model to allow it to perform ensemble integrations. Step 4 completes the data assimilation program with the analysis step. Finally, step 5 is optional to obtain information on the computing time and required memory.
-The implementation steps are described on the pages linked above. An example of the implementation is given in tutorial cose provided with PDAF  in `tutorial/online_2D_serialmodel/` and `tutorial/online_2D_serialmodel/`. (The [PdafTutorial tutorial] also provides detail explanations of the implementation steps).

-Several subroutines that contain model and observation specific operations are called as call-back routines by PDAF. For this, PDAF defines interfaces for all routines. These routines need to be implemented by the user. The operations in all these routines are rather elementary like the initialization of the model's physical fields from a state vector provided by PDAF and the initialization of the vector of observations. The examples mentioned above also include example implementations for these routines. In addition, the directory `templates/` contains template implementations of the routines that can be used as a basis for new implementations.

 An overview of the available options for each filter that can be specified when PDAF is initialized is given on the [wiki:AvailableOptionsforInitPDAF overview page on options].
