 ### Tokens and installing apps
 Slack apps use [OAuth to manage access to Slack's APIs](https://api.slack.com/docs/oauth). When an app is installed, you'll receive a token that the app can use to call API methods. 
 
-There are two token types available to a Slack app: user (`xoxp`) and bot (`xoxb`) tokens. User tokens allow you to call API methods on behalf of users after they install or authenticate the app. There may be several user tokens for a single workspace. Bot tokens are granted once in every workspace where someone installs the app, though they require adding a bot user to your app. The bot token your app uses will be the same no matter which user performed the installation.

User tokens allow you to call API methods on behalf of users after they install or authenticate the app. There may be several user tokens for a single workspace. Bot tokens are associated with bot users, and are only granted once in a workspace where someone installs the app. The bot token your app uses will be the same no matter which user performed the installation. Bot tokens are the token type that _most_ apps use.
 
 For brevity, we're going to use bot tokens for this guide.
 
-To add a bot user, click **Bot Users** on the left sidebar and then **Add A Bot User**. Give it a display name and username, then click **Add Bot User**.
+Navigate to the **OAuth & Permissions** on the left sidebar and scroll down to the **Bot Token Scopes** section. Click **Add an OAuth Scope**.
 
-Now that you have a bot user with permission to send messages to Slack, let's install the app to your workspace.
+For now, we'll just add one scope: [`chat:write`](https://api.slack.com/scopes/chat:write). This grants your app the permission to post messages in channels it's a member of.
 
-Click **Install App** on the left sidebar and click the **Install App to Workspace** button at the top of the page. You'll see a screen that details what permissions the app is requesting, which correlate to the scopes applied to your app's OAuth token(s).
+Scroll up to the top of the OAuth & Permissions page and click **Install App to Workspace**. You'll be led through Slack's OAuth UI, where you should allow your app to be installed to your development workspace.
 
-Once you authorize the installation, you'll land on the **OAuth & Permissions** page.
+Once you authorize the installation, you'll land on the **OAuth & Permissions** page and see a **Bot User OAuth Access Token**.

-You'll see two tokens. For now, we'll just use the `xoxb` bot token. (If you scroll down this page to the **Scopes** section, you'll see the various scopes you can add to the `xoxp` token.)

 > 💡 Treat your token like a password and [keep it safe](https://api.slack.com/docs/oauth-safety). Your app uses it to post and retrieve information from Slack workspaces.
