+# Install {{% param "PRODUCT_NAME" %}} with Chef
+
+You can use Chef to install and manage {{< param "PRODUCT_NAME" >}}.
+
+## Before you begin
+
+- These steps assume you already have a working [Chef][] setup.
+- You can add the following resources to any new or existing recipe you choose.
+- These tasks install {{< param "PRODUCT_NAME" >}} from the package repositories. The tasks target Linux systems from the following families:
+  - Debian (including Ubuntu)
+  - RedHat Enterprise Linux
+  - Amazon Linux
+  - Fedora
+
+## Steps
+
+To add {{% param "PRODUCT_NAME" %}} to a host:
+
+1. Add the following resources to your [Chef][] recipe to add the Grafana package repositories to your system:
+    ```ruby
+    if platform_family?('debian', 'rhel', 'amazon', 'fedora')
+      if platform_family?('debian')
+        remote_file '/etc/apt/keyrings/grafana.gpg' do
+          source 'https://apt.grafana.com/gpg.key'
+          mode '0644'
+          action :create
+          end
+
+        file '/etc/apt/sources.list.d/grafana.list' do
+          content "deb [signed-by=/etc/apt/keyrings/grafana.gpg] https://apt.grafana.com/ stable main"
+          mode '0644'
+          notifies :update, 'apt_update[update apt cache]', :immediately
+        end
+
+        apt_update 'update apt cache' do
+          action :nothing
+        end
+      elsif platform_family?('rhel', 'amazon', 'fedora')
+        yum_repository 'grafana' do
+          description 'grafana'
+          baseurl 'https://rpm.grafana.com/oss/rpm'
+          gpgcheck true
+          gpgkey 'https://rpm.grafana.com/gpg.key'
+          enabled true
+          action :create
+          notifies :run, 'execute[add-rhel-key]', :immediately
+        end
+
+        execute 'add-rhel-key' do
+          command "rpm --import https://rpm.grafana.com/gpg.key"
+          action :nothing
+        end
+      end
+    else
+        fail "The #{node['platform_family']} platform is not supported."
+    end
+    ```
+1. Add the following resources to install and enable the `grafana-agent-flow` service:
+    ```ruby
+    package 'grafana-agent-flow' do
+      action :install
+      flush_cache [ :before ] if platform_family?('amazon', 'rhel', 'fedora')
+      notifies :restart, 'service[grafana-agent-flow]', :delayed
+    end
+
+    service 'grafana-agent-flow' do
+      service_name 'grafana-agent-flow'
+      action [:enable, :start]
+    end  
+    ```
+
+## Configuration
+
+The `grafana-agent-flow` package installs a default configuration file that doesn't send telemetry anywhere.
+
+The default configuration file location is `/etc/grafana-agent-flow.river`. You can replace this file with your own configuration, or create a new configuration file for the service to use.
