 class property_cache_pickle(object):
     """
-    Class to cache properties, which take longer on initialising than reading a file in pickle format.
+    This class caches the data from a given `source_instance`. It takes the data from the cache instead of generating the data from the `source_instance`,
+    if the conditions for the cache usage are given.
+
+    .. admonition:: Required properties for the `source_instance`
+
+                * **uid():** returns the unique id of the source's source or None, if you don't want to use the unique id.
+                * **keys():** returns a list of all available keys.
+                * **data_version():** returns a version number of the current data (it should be increased, if the get method of the source instance returns improved values or the data structure had been changed).
+                * **get(key, default):** returns the property for a key. If key does not exists, default will be returned.
+    
+    .. hint:: You are able to use all parameters and methods of the `source_instance` identically with the property_cache instance.
 
     :param source_instance: The source instance holding the data
     :type source_instance: instance
     :param cache_filename: File name, where the properties are stored as cache
     :type cache_filename: str
-    :param load_all_on_init: Optionally init behaviour control parameter. True will load all available properties from source on init, False not.
-    :param max_age: The maximum age of the cache object, after that time the source will be used for getting information.
-    :type max_age: int
-    :param store_on_get: Parameter to enable / disable cache storage on get. If you disble data storage, you need to update and store the cache manually
-
-    .. note:: source_instance needs to have at least the following methods: uid(), keys(), data_version(), get()
-
-                * uid(): returns the unique id of the source.
-                * keys(): returns a list of all available keys.
-                * data_version(): returns a version number of the current data (it should be increased, if the get method of the source instance returns improved values or the data structure had been changed).
-                * get(key, default): returns the property for a key. If key does not exists, default will be returned.
-
-    Reasons for updating the complete data set:
-
-    * UID of source_instance has changed (in comparison to the cached value).
-    * data_version is increased
+    :param load_all_on_init: True will load all data from the source instance, when the cache will be initialised the first time.
+    :type load_all_on_init: bool
+    :param callback_on_data_storage: The callback will be executed every time when the cache file is stored. It will be executed with the instance of this class as first argument.
+    :type callback_on_data_storage: method
+    :param max_age: The maximum age of the cached data in seconds or None for no maximum age.
+    :type max_age: int or None
+    :param store_on_get: False will prevent cache storage with execution of the `.get(key, default)` method. You need to store the cache somewhere else.
+    :type store_on_get: bool
+
+    .. admonition:: The cache will be used, if all following conditions are given
+
+                * The key is in the list returned by `.keys()` method of the `source_instance`
+                * The key is not in the list of keys added by the `.add_source_get_keys()` method.
+                * The cache age is less then the given max_age parameter or the given max_age is None.
+                * The uid of the source instance (e.g. a checksum or unique id of the source) is identically to to uid stored in the cache.
+                * The data version of the `source_instance` is <= the data version stored in the cache.
+                * The value is available in the previous stored information
