 We can store bits of information we'll want to access later as attributes on the bot object and actions we want our bot to take as methods.
 
-### Init Your Bot's Identity
-
-In the `__init__` function of the Bot class, which (as the name suggests) initializes the bot, we're giving our bot a touch of identity. Feel free to change the name and emoji here!
-
 Instead of importing the `python-slackclient` library in our `app.py` file like we did before, we'll import it into this file and access the `SlackClient` through an attribute on our bot. This makes it easier to handle OAuth since our bot object's attributes can be accessed in the other places it will live, such as the `app.py` file.

 Now that we've been authorized, let's teach our bot to respond to users who want to say hello!

 ### Bot Response Methods
 
 Once `app.py` holds a function to handle the `message` events we want our bot to respond to, we'll need to build a method on our `Bot` class to respond.
 
-In `bot.py` you'll see we've started a method called `say_hello` to respond to a user's message in the `#general` channel. Since we already know that we want to say hello at this point, what we'll need to do is get the `user_id` that we've passed as a parameter and build a call to the Slack API's `chat.postMessage` endpoint.

 It should look something like this:

 ```python

 ## You Did It! :sparkles:
 
-You should have a working bot! If you're looking for ways to make your bot fancier, look into adding more interaction with [message buttons](https://api.slack.com/docs/message-buttons) or integrating some NLP with a lovely service like [api.ai.](https://api.ai/)
