+# IIS
+
+Deploy Nitro apps to IIS.
+
+::alert{type="warning"}
+This is an experimental preset.
+::
+
+## Using [IISnode](https://github.com/Azure/iisnode) (recommended)
+
+**Preset:** `iis-node` ([switch to this preset](/deploy/#changing-the-deployment-preset))
+
+1. Install [IISnode](https://github.com/azure/iisnode/releases), and the [IIS URL Rewrite Module](https://www.iis.net/downloads/microsoft/url-rewrite).
+2. In IIS, add `.mjs` as a new mime type and set its content type to `application/javascript`.
+3.  Deploy the contents of your `.output` folder to your website in IIS.
+
+
+## Using IIS directly
+
+**Preset:** `iis-handler` ([switch to this preset](/deploy/#changing-the-deployment-preset))
+
+If you do not wish to use IISnode, you can use IIS directly.
+
+1. Make sure that [Node.js](https://nodejs.org/en/) is installed on your Windows Server.
+2. Make sure [`HttpPlatformHandler` Module](https://www.iis.net/downloads/microsoft/httpplatformhandler) is installed.
+3.  Copy your `.output` directory into the Windows Server, and create a website on IIS pointing to that exact directory.
