 ## Overview
 
-This sample Bot shows how to use the Mattermost [Go driver](https://github.com/mattermost/mattermost-server/blob/master/model/client4.go) to interact with a Mattermost server, listen to events and respond to messages. Documentation for the Go driver can be found [here](https://godoc.org/github.com/mattermost/mattermost-server/model#Client).

 Highlights of APIs used in this sample:
- - Log in to the Mattermost server
- - Create a channel
- - Modify user attributes 
- - Connect and listen to WebSocket events for real-time responses to messages
- - Post a message to a channel
 
-This Bot Sample was tested with Mattermost server version 3.10.0.
+- Log in to the Mattermost server

+
+This Bot Sample was tested with Mattermost server version 7.5.2.
 
 ## Setup Server Environment
 
 ### Via Docker And Docker-Compose
-1 - Ensure [Docker](https://www.docker.com/get-started) and [Docker-Compose](https://docs.docker.com/compose/install/) are installed for your system
 
-2 - Run `./add_users.sh`. The login information for the Mattermost client will be printed
+1 - Ensure [Docker](https://www.docker.com/get-started) and [Docker-Compose](https://docs.docker.com/compose/install/) are installed on your system.
+
+2 - Run `docker-compose up -d --build` and the mattermost client will be built and will expose the port `8065` to your system's localhost.
+
+3 - Run `./add_users.sh`. The login information for the Mattermost client will be printed.
+
+4 - Log into your mattermost instance using these credentials and create a bot account following [these](https://developers.mattermost.com/integrate/reference/bot-accounts/) instructions.
 
-3 - Run `docker-compose up -d --build` and the mattermost client will be built and will expose the port `8065` to your system's localhost
+5 - Copy `example.env` to `.env` and fill in the bot token (obtained from the previous step), team name, etc. Alternatively, just provide your credentials as environment variables.
+
+5 - Start the Bot.
 
-4 - Start the Bot.
 ```
 make run
 ```
-You can verify the Bot is running when 
-  - `Server detected and is running version X.Y.Z` appears on the command line.
-  - `Mattermost Bot Sample has started running` is posted in the `Debugging For Sample Bot` channel.
+
+You can verify the Bot is running when
+
+- `Logged in to mattermost` appears on the command line.
+- `Hi! I am a bot.` is posted in your specified channel.
 
 See "Test the Bot" for testing instructions
+
 ### Via Direct System Install/Setup
-1 - [Install](http://docs.mattermost.com/install/requirements.html) or [upgrade](https://docs.mattermost.com/administration/upgrade.html) to Mattermost server version 3.10+, and verify that the Mattermost server is running on [http://localhost:8065](http://localhost:8065). 
+
+1 - [Install](http://docs.mattermost.com/install/requirements.html) or [upgrade](https://docs.mattermost.com/administration/upgrade.html) to Mattermost server version 3.10+, and verify that the Mattermost server is running on [http://localhost:8065](http://localhost:8065).
 
 On the commands below, if you are running Mattermost server version 5.0 or later, use `./bin/mmctl`. If you are running version 4.10 or earlier, use `./bin/platform`.
 
 Learn more about the `mmctl` CLI tool in the [Mattermost documentation](https://docs.mattermost.com/administration/mmctl-cli-tool.html).
 
-2 - Create a team for the Bot to run. If you have an existing team, you may skip this step and replace `team_name` with your existing team in subsequent steps.
+2 - Create a team for the Bot to run. If you have an existing team, you may skip this step and replace `botsample` with your existing team in subsequent steps.
+
 ```
 ./bin/mmctl team create --name botsample --display_name "Sample Bot playground" --email "[email protected]"
 ```
-3 - Create the user account the Bot will run as.
-```
-./bin/mmctl user create --email="[email protected]" --password="Password1!" --username="samplebot"
-```
-4 - Create a second user, `bill`, which we will use to log in and interact with the Bot.
+
+3 - Create a user, `bill`, which we will use to log in and interact with the Bot.
+
 ```
 ./bin/mmctl user create --email="[email protected]" --password="Password1!" --username="bill"
 ```
-5 - (Optional) Give `bill` `system_admin` permissions.
+
+4 - (Optional) Give `bill` `system_admin` permissions.
+
 ```
 ./bin/mmctl roles system_admin bill
 ```
-6 - Add users to the team
-```
-./bin/mmctl team add botsample samplebot bill
-```
-7 - Verify the e-mail address
-```
-./bin/mmctl user verify samplebot
-```
-8 - Log in to [http://localhost:8065](http://localhost:8065) as `bill` and verify the account was created successfully. Then, navigate to the `botsample` team you created in step 2 to interact with the Bot.
+
+5 - Log in to [http://localhost:8065](http://localhost:8065) as `bill` and verify the account was created successfully.
+
+6 - Create a bot account following [these](https://developers.mattermost.com/integrate/reference/bot-accounts/) instructions.
+
+7 - Copy `example.env` to `.env` and fill in the bot token (obtained from the previous step), team name, etc. Alternatively, just provide your credentials as environment variables.
 
 ## Setup Bot Development Environment
 
 1 - Follow the [Developer Machine Setup](https://docs.mattermost.com/developer/dev-setup.html) instructions to setup the bot development environment.
 
 2 - Clone the GitHub repository to run the sample.
+
 ```
 git clone https://github.com/mattermost/mattermost-bot-sample-golang.git
 cd mattermost-bot-sample-golang
 ```
-3 - Start the Bot.
+
+3 - Log into your mattermost instance using these credentials and create a bot account following [these](https://developers.mattermost.com/integrate/reference/bot-accounts/) instructions.
+
+4 - Copy `example.env` to `.env` and fill in the bot token (obtained from the previous step), team name, etc. Alternatively, just provide your credentials as environment variables.
+
+5 - Run with
+
 ```
 make run
 ```
-You can verify the Bot is running when 
-  - `Server detected and is running version X.Y.Z` appears on the command line.
-  - `Mattermost Bot Sample has started running` is posted in the `Debugging For Sample Bot` channel.
+
+You can verify the Bot is running when
+
+- `Logged in to mattermost` appears on the command line.
+- `Hi! I am a bot.` is posted in your specified channel.
 
 ## Test the Bot
 
 1 - Log in to the Mattermost server as `[email protected]` and `Password1!`.
 
-2 - Join the `Debugging For Sample Bot` channel.
+2 - Join your specified channel.
 
-3 - Post a message in the channel such as `are you running?` to see if the Bot responds. You should see a response similar to `Yes I'm running` if the Bot is running.
+3 - Post a message in the channel such as `hello?` to see if the Bot responds. You should see a response if the Bot is running.
 
 ## Stop the Bot
 
-1 - In the terminal window, press `CTRL+C` to stop the bot. You should see `Mattermost Bot Sample has stopped running` posted in the `Debugging For Sample Bot` channel.
+1 - In the terminal window, press `CTRL+C` to stop the bot.
