 This Bolt for Python template demonstrates how to build [AI Apps](https://docs.slack.dev/ai/) in Slack.
 
+Models from [OpenAI](https://openai.com) are used and can be customized for prompts of all kinds.
+
 ## Setup
+
 Before getting started, make sure you have a development workspace where you have permissions to install apps. If you don’t have one setup, go ahead and [create one](https://slack.com/create).
 
 ### Developer Program
+
 Join the [Slack Developer Program](https://api.slack.com/developer-program) for exclusive access to sandbox environments for building and testing your apps, tooling, and resources created to help you build and grow.
 
 ## Installation
 
-#### Create a Slack App
+Add this app to your workspace using either the Slack CLI or other development tooling, then read ahead to configuring LLM responses in the **[Providers](#providers)** section.
+
+### Using Slack CLI
+
+Install the latest version of the Slack CLI for your operating system:
+
+- [Slack CLI for macOS & Linux](https://docs.slack.dev/tools/slack-cli/guides/installing-the-slack-cli-for-mac-and-linux/)
+- [Slack CLI for Windows](https://docs.slack.dev/tools/slack-cli/guides/installing-the-slack-cli-for-windows/)
+
+You'll also need to log in if this is your first time using the Slack CLI.
+
+```sh
+slack login
+```
+
+#### Initializing the project
+
+```sh
+slack create my-bolt-python-assistant --template slack-samples/bolt-python-assistant-template
+cd my-bolt-python-assistant
+```
+
+#### Creating the Slack app
+
+Use the following command to add your new Slack app to your development workspace. Choose a "local" app environment for upcoming development:
+
+```sh
+slack install
+```
+
+After the Slack app has been created you're all set to configure the LLM provider!
+
+### Using Terminal
+
 1. Open [https://api.slack.com/apps/new](https://api.slack.com/apps/new) and choose "From an app manifest"
 2. Choose the workspace you want to install the application to
-3. Copy the contents of [manifest.json](./manifest.json) into the text box that says `*Paste your manifest code here*` (within the JSON tab) and click *Next*
-4. Review the configuration and click *Create*
-5. Click *Install to Workspace* and *Allow* on the screen that follows. You'll then be redirected to the App Configuration dashboard.

-### Environment Variables
+#### Environment Variables
 
 Before you can run the app, you'll need to store some environment variables.
 
-
 1. Rename `.env.sample` to `.env`.
 2. Open your apps setting page from [this list](https://api.slack.com/apps), click _OAuth & Permissions_ in the left hand menu, then copy the _Bot User OAuth Token_ into your `.env` file under `SLACK_BOT_TOKEN`.
-```zsh
+
+```sh
 SLACK_BOT_TOKEN=YOUR_SLACK_BOT_TOKEN
 ```
+
 3. Click _Basic Information_ from the left hand menu and follow the steps in the _App-Level Tokens_ section to create an app-level token with the `connections:write` scope. Copy that token into your `.env` as `SLACK_APP_TOKEN`.
-```zsh
+
+```sh
 SLACK_APP_TOKEN=YOUR_SLACK_APP_TOKEN
 ```
-4. Save your OpenAI key into `.env` under `OPENAI_API_KEY`.
-```zsh
-OPENAI_API_KEY=YOUR_OPEN_API_KEY
-```
