+
+This guide will walk you through the process of managing resource groups in Radius. For more information on resource groups, see [Resource groups]({{< ref groups >}}).
+
+## Pre-requisites
+
+- [Supported Kubernetes cluster]({{< ref supported-clusters >}})
+- [Radius CLI]({{< ref howto-rad-cli >}})
+
+## Step 1: Ensure Radius is installed
+
+Begin by making sure that Radius is installed on your Kubernetes cluster:
+
+```bash
+rad install kubernetes
+```
+
+## Step 2: Create a resource group
+
+Run [`rad group create`]({{< ref rad_group_create >}}) to create a resource group:
+
+```bash
+rad group create myGroup
+```
+
+You should see:
+
+```
+creating resource group "myGroup" in namespace "default"...
+
+resource group "myGroup" created
+```
+
+## Step 3: View your resource group
+
+Run [`rad group show`]({{< ref rad_group_show >}}) to view the your resource group:
+
+```bash
+rad group show myGroup
+```
+
+You should see:
+
+```
+ID                                            NAME                
+/planes/radius/local/resourcegroups/myGroup   myGroup
+```
+
+You can use the `-o json` flag to view more information about the resource group:
+
+```bash
+rad group show -o json
+```
+
+You should see:
+
+```
+{
+    "id": "/planes/radius/local/resourcegroups/myGroup",
+    "location": "global",
+    "name": "myGroup",
+    "tags": {},
+    "type": "System.Resources/resourceGroups",
+}
+```
+
+## Step 4: Set your resource group as the default
+
+Setting a default resource group allows you to run commands like `rad deploy` without specifying the `-g/--group` flag explicitly every time. Run [`rad group switch`]({{< ref rad_group_switch >}}) to set your new resource group as the default:
+
+```bash
+rad group switch myGroup
+```
+
+You can now run `rad deploy` or `rad recipe list` without needing to specify the group.
+
+## Step 5: Delete your resource group
+
+Run [`rad group delete`]({{< ref rad_group_delete >}}) to delete a resource group:
+
+```bash
+rad group delete myGroup
+```
