+## Building from source
+
+To build this module from source run `./build.ps1`.
+This build script will compile the module and documentation then output the result into `out/modules/PSRule.Rules.CAF`.
+
+The following PowerShell modules will be automatically downloaded if the required versions are not present:
+
+- PlatyPS
+- Pester
+- PSScriptAnalyzer
+- PowerShellGet
+- PackageManagement
+- InvokeBuild
+
+These additional modules are only required for building PSRule and are not required for running PSRule.
+
+If you are on a network that does not permit Internet access to the PowerShell Gallery,
+download these modules on an alternative device that has access.
+The following script can be used to download the required modules to an alternative device.
+After downloading the modules copy the module directories to devices with restricted Internet access.
+
+```powershell
+# Save modules, in the .\modules directory
+Save-Module -Name PlatyPS, Pester, PSScriptAnalyzer, PowerShellGet, PackageManagement, InvokeBuild -Repository PSGallery -Path '.\modules';
+```
+
+Additionally .NET Core SDK v3.1 is required.
+.NET Core will not be automatically downloaded and installed.
+To download and install the latest SDK see [Download .NET Core 3.1][dotnet].
