 # Introduction
 Hey, this wiki page will walk you through the inline keyboard example found [here](../blob/master/examples/inlinekeyboard.py). We will start with how python starts with the example, then follow through the code in the same way we expect updates from the user would go through it. Let's do it.

-We introduced the usage of `__slots__` in v13.6, which can reduce memory usage and improve performance. In v14 we removed the ability to set custom attributes on all objects except for `ext.CallbackContext`. To store data, we recommend to use PTBs built-in mechanism for [storing data](Storing-bot,-user-and-chat-related-data) instead. If you want to add additional functionality to some class, we suggest to subclass it.
