+Choose how AyaNova will be used for specific Windows installation instructions. Note that it's possible to switch to an alternative configuration via backup and restore if needs change later however if there is a possibility that AyaNova will be accessed from the internet it's recommended to install as an IIS hosted application.

+## Single user installation
 
-## Windows hosting
-If you are using a Windows hosting provider with shell access follow the [Server with local office and external internet users](ops-install-windows-internet.md) guide
+This type of install is appropriate for using AyaNova locally on a single personal computer only. This type of installation is _not_ appropriate for sharing with multiple users.
 
+[Single user install guide](ops-install-windows-single.md)
 
+## Shared multiple user installation
+
+When more than one user will be accessing AyaNova it can be set up in two different ways.
+
+### AyaNova server direct
+
+AyaNova running alone and access directly by users within a local office network.
+
+This type of install is appropriate for use within a local area network _only_. It is _not_ suitable for sharing with outside users from the Internet.
+
+Pros:
+
+- Simpler to install
+- Does not require IIS
+
+Cons:
+
+- Server Windows computer must be kept logged in to run AyaNova server as a desktop application
+- AyaNova server application will not automatically restart if it's closed on the desktop
+- Not suitable for sharing with users / Customers outside the local area network via the internet

+[Local network direct access install guide](ops-install-windows-lan.md)
+
+AyaNova server in this configurataion is run as a desktop application on a computer that is accessible to other users w
+
+### AyaNova server hosted through IIS (recommended)
+
+AyaNova hosted via Microsoft Internet Information Server that is included with most editions of Windows.
+
+This type of install is the most future proof and appropriate for users who access AyaNova from the Internet in addition to local users accessing via a local area network.
+
+Pros:
+
+- IIS manages AyaNova and ensures it stays running and will restart if necessary
+- Secured via IIS for remote users and optionally Customers on the Internet
+- Can use an SSL certificate in IIS which ensures all communications are encrypted between remote users and the AyaNova server
+- A true **server** configuration; IIS server will start AyaNova automatically without the need to login to Windows
+
+Cons:
+
+- Requires IIS to be enabled in Windows and some manual steps to configure IIS to use AyaNova

+
+## Off-premise Windows hosting
+
+If a Windows hosting provider is being used with shell access follow the [Internet access via IIS install guide](ops-install-windows-internet.md) guide.

+(note that a Linux hosting provider can be used and is generally recommended over Windows hosting purely for financial reasons, there is no practical difference from a technical standpoint between Linux or Windows hosted AyaNova)
