+To get the most from this course and follow along with the sample code, you'll need to have access to a Redis Stack 7 server and have Python 3 installed.
 
 ### Prerequisites
 
 In order to run the sample code, you will need:
 
 * [Python 3](https://www.python.org/downloads/).
 * Ability to run the `pip` command for Python 3.
-* Access to a local or remote installation of [Redis](https://redis.io/download) version 6.2 or newer (local preferred).  We've provided a Docker Compose file to make this easy for you.  If you don't want to use Docker, [follow the instructions here](https://redis.io/docs/getting-started/) to install Redis using a package manager.

-#### Starting Redis (when installed by a Package Manager)
-
-If you installed Redis using a package manager, start the Redis server if it isn't already running.  For example, if you installed Redis with the Homebrew package manager for macOS you'd start it like this:
-
-```bash
-brew services start redis
-```
-
-You can now run `redis-cli` to connect to Redis as follows:
-
-```bash
-docker exec -it redis_ru202 redis-cli
-```
-
-Type `quit` to exit `redis-cli` back to your shell.
-
-When you are done with Redis, you can optionally turn off the server.  For example if Redis was installed with the Homebrew package manager for macOS you'd stop the server like this:
-
-```bash
-brew services stop redis
-```

 ### Configuration
 
-By default, the code will assume that Redis is available on `localhost` at port `6379`.  If your Redis instance is running elsewhere, you will need to set the `REDIS_HOST` and/or `REDIS_PORT` environment variables.  For example, here's how to configure these to connect to Redis on `myredishostname` port `6380`:

 ### Running the Example Code
 
-Throughout the course, you will be asked to run the example code for the various exercises.  Some of these require you to open multiple shell/terminal sessions.  Don't forget to start your Python virtual environment in each new shell session.  You'll also need to set the environment variables `REDIS_HOST`, `REDIS_PORT` and optionally `REDIS_USER` and `REDIS_PASSWORD` if your Redis instance is not running on `localhost:6379`.

 ### Optional (but recommended!): RedisInsight
 
 RedisInsight is a graphical management tool for Redis.  It allows you to view and edit data in Redis, and contains specialized views for looking at the contents of Redis Streams.
 
 You don't need to install or use RedisInsight to be successful with this course, but we'd recommend you give it a try.
 
-[Download RedisInsight here](https://redis.com/redis-enterprise/redis-insight/) (it's free!).  Once installed, add a new Redis database and supply the hostname, port and optionally password for the Redis instance that you're using for this course (this will usually be `localhost`, `6379` and no password).

+
+If you're using the Docker Compose file provided with this course, you can also try out a limited version of RedisInsight in your browser by visiting `http://localhost:8081` - this version can only connect to the Redis Stack instance in the Docker container.  Use the Desktop version of RedisInsight to manage connections to multiple remote and/or local Redis instances.
