 Before you get started with Redis OM, make sure you start Redis.

 ### Ubuntu Linux (Including WSL)
 
 If you installed Redis using `apt`, start it with the `systemctl` command:
 
-    sudo systemctl restart redis.service
+    $ sudo systemctl restart redis.service
 
 Otherwise, you can start the server manually:
 
-    redis-server start
+    $ redis-server start
 
 ### macOS with Homebrew
 
-    brew services start redis
+    $ brew services start redis
 
 ### Docker
 
 The command to start Redis with Docker depends on the image you've chosen to use.
 
+**TIP:** The `-d` option in these examples runs Redis in the background, while `-p 6379:6379` makes Redis reachable at port 6379 on your localhost.

 #### Docker with the `redismod` image (recommended)
 
-    docker run -d -p 6379:6379 redislabs/redismod
+    $ docker run -d -p 6379:6379 redislabs/redismod
 
 ### Docker with the `redis` image
 
-    docker run -d -p 6379:6379 redis
+    $ docker run -d -p 6379:6379 redis
 
 ## Installing Redis OM
 
-You can install Redis OM with `pip` by running the following command:
+The recommended way to install Redis OM is with [Poetry](https://python-poetry.org/docs/). You can install Redis OM using Poetry with the following command:
+
+    $ poetry install redis-om
+
+If you're using Pipenv, the command is:
 
-    pip install redis-om
+    $ pipenv install redis-om

-With Pipenv, the command is:
+**TIP:** If you aren't using Poetry or Pipenv and are instead installing directly with `pip`, we recommend that you install Redis OM in a virtual environment (AKA, a virtualenv). If you aren't familiar with this concept, see [Dan Bader's video and transcript](https://realpython.com/lessons/creating-virtual-environment/).
