+### Manage Windows Agent
+
+This module supports Windows Sensu Go agent starting with version 5.7.0.
+
+The Windows package source must be specified as either a URL, a Puppet source or a filesystem path.
+
+Install sensu-go-agent on Windows from URL:
+
+```puppet
+class { 'sensu::agent':
+  package_source => 'https://s3-us-west-2.amazonaws.com/sensu.io/sensu-go/5.7.0/sensu-go-agent_5.7.0.2380_en-US.x64.msi',
+}
+```
+
+Install sensu-go-agent on Windows from Puppet source:
+
+```puppet
+class { 'sensu::agent':
+  package_source => 'puppet:///modules/profile/sensu/sensu-go-agent.msi',
+}
+```
+
+If a system already has the necessary MSI present it can be installed without downloading from an URL:
+
+```puppet
+class { 'sensu::agent':
+  package_source => 'C:\Temp\sensu-go-agent.msi',
+}
+```
+
 ### Advanced agent
 
 If you wish to change the `agent` password you must provide the new and old password.
