 Before starting this tutorial, you will need to have access to an AWS account in which you are allowed to provision resources. This tutorial also assumes you've already created a SendGrid account with free-tier access. Finally, it is highly recommended you utilize [virtualenv](https://virtualenv.pypa.io/en/stable/).

 # Integrate with Slack Events API
 
-It's fairly straightforward to integrate Sendgrid with Slack, to allow emails to be triggered by events happening on Slack.
+It's fairly straightforward to integrate SendGrid with Slack, to allow emails to be triggered by events happening on Slack.
 
 For this, we make use of the [Official Slack Events API](https://github.com/slackapi/python-slack-events-api), which can be installed using pip.
 
 To allow our application to get notifications of slack events, we first create a Slack App with Event Subscriptions as described [here](https://github.com/slackapi/python-slack-events-api#--development-workflow)
 
-Then, we set `SENDGRID_API_KEY` _(which you can create on the Sendgrid dashboard)_ and `SLACK_VERIFICATION_TOKEN` _(which you can get in the App Credentials section of the Slack App)_ as environment variables.
+Then, we set `SENDGRID_API_KEY` _(which you can create on the SendGrid dashboard)_ and `SLACK_VERIFICATION_TOKEN` _(which you can get in the App Credentials section of the Slack App)_ as environment variables.
 
 Once this is done, we can subscribe to [events on Slack](https://api.slack.com/events) and trigger emails when an event occurs. In the example below, we trigger an email to `test@example.com` whenever someone posts a message on Slack that has the word "_help_" in it.
