 ## Local Data Pools
 
+The local data pools can be used to store data like sensor values so they can be used 
+by other software objects like controllers as well. If a class should have a local pool which
+can be used by other software objects as well, following steps have to be performed:
 
+1. Create a `LocalDataPoolManager` member class
+2. Implement the `HasLocalDataPoolIF`
+
+The local data pool manager is also able to process housekeeping service requests in form
+of messages, generate periodic housekeeping packet, generate notification and snapshots of changed
+variables and datasets and process notifications and snapshots coming from other objects.
+Two important framework classes already perform the two steps shown above so the steps required
+are altered slightly. 
+
+### Storing and Accessing pool data 
+
+The pool manager is responsible for thread-safe access of the pool data, but the actual
+access to the pool data is done via proxy classes like pool variable classes or dataset classes.
+Generally, a user will create a dataset class which in turn groups all cohesive pool variables.
+
+The user can then use this set class to `read` the variables and `commit` changed variables
+back into the pool.
+
+### Using the local data pools of the `DeviceHandlerBase`
+
+It is very common to store data generated by devices like a sensor into a pool which can 
+then be used by other objects. Therefore, the `DeviceHandlerBase` already has a
+local pool. The
