+A simple object cache for Kodi addons
+
+
+## Help needed with maintaining !
+I am very busy currently so I do not have a lot of time to work on this project or watch the forums.
+Be aware that this is a community driven project, so feel free to submit PR's yourself to improve the code and/or help others with support on the forums etc. If you're willing to really participate in the development, please contact me so I can give you write access to the repo. I do my best to maintain the project every once in a while, when I have some spare time left.
+Thanks for understanding!
+
+
+## Usage
+
+You can use this python library as module within your own Kodi scripts/addons.
+Just make sure to import it within your addon.xml:
+
+```xml
+<requires>
+    <import addon="script.module.simplecache" version="1.0.14" />
+</requires>
+```
+
+Now, to use it in your Kodi addon/script, make sure to import it and you can access its methods.
+
+```python
+import simplecache
+
+# instantiate the cache
+_cache = simplecache.SimpleCache()
+
+# get data from cache
+mycache = _cache.get("MyAddon.MyChunkOfData")
+if mycache:
+    my_objects = mycache
+else:
+    # do stuff here
+    my_objects = mymethod()
+
+    # write results in cache
+    _cache.set( "MyAddon.MyChunkOfData", my_objects, expiration=datetime.timedelta(hours=12))
+```
+
+The above example will check the cache for the key "MyAddon.MyChunkOfData". If there is any data (and the cache is not expired) it will be returned as the original object.
+
+If the cache is empty, you perform the usual stuff to get the data and save that to the cache
+
+---------------------------------------------------------------------------
+
+## Available methods
+
+### get(endpoint, checksum="", json=False)
+```
+    Returns the data from the cache for the specified endpoint. Will return None if there is no cache.
+
+    parameters:
+    endpoint --> Your unique reference/key for the cache object. TIP: To prevent clashes with other addons, prefix with your addon ID.
+    checksum --> Optional argument to check for a checksum in the file (Will only work if you store the checksum with the set method). Can be any python object which can be serialized with eval.
+    json --> Optional argument. Default is False. For JSON data it is recommended to switch it to True to avoid Memomy Error exceptions or other issues. If you set the global "data_is_json" bool to True, it will always handle your data as JSON.
+
+
+    Example: _cache.get("MyAddon.MyChunkOfData", checksum=len(myvideos))
+
+    This example will return the data in the cache but only if the length of the list myvideos is the same as whatever is stored as checksum in the cache.
+
+```
+
+### set(endpoint, data, checksum="", expiration=timedelta(days=30), json=False)
+```
+    Stores the data in the cache for the specified endpoint.
+
+    parameters:
+    endpoint --> Your unique reference/key for the cache object. TIP: To prevent clashes with other addons, prefix with your addon ID.
+    data --> Your objectdata. Can be any python object which can be serialized with eval.
+    checksum --> Optional argument to store as checksum in the file. Can be any python object which can be serialized with eval.
+    expiration --> Optional argument to specify the amount of time the data may be cached as python timedelta object. Defaults to 30 days if ommitted.
+    json --> Optional argument. Default is False. For JSON data it is recommended to switch it to True to avoid Memomy Error exceptions or other issues. If you set the global "data_is_json" bool to True, it will always handle your data as JSON.
+
+    Example: _cache.set("MyAddon.MyGreatChunkOfData", my_objects, checksum=len(myvideos), expiration=timedelta(hours=1))
+
+    This example will store the data in the cache which will expire after 1 hours. Additionally a checksum is stored in the cache object.
+
+```
+
+## Notes
+
+1) By default objects will be stored both in memory and on disk, it is however possible to override that:
+```
+    _cache.enable_mem_cache = False
+```
+In that case, objects will only be stored on disk (database)
+
+
+2) Cache objects are auto cleaned from memory after 2 hours to prevent unused objects loaded in memory.
+
+
+3) Cache objects on disk are stored in a self-maintaining sqllite database. Expired objects will be auto cleaned from the database.
+
+4) If your data is only JSON you can set a global bool to handle all input/ouput requests as JSON. This is recommended to avoid problems and issues on slower devices.
+```
+    _cache.data_is_json = True
+```
