 - Be prepared to discuss a feature and take feedback.
 - Include unit tests and updates documentation to complement the change.
 
+When you are ready to contribute a fix or feature:
+
+- Start by [forking the PSRule repo][github-fork].
+- Create a new branch from master in your fork.
+- Add commits in your branch.
+  - If you have updated module code also update `CHANGELOG.md`.
+  - You don't need to update the `CHANGELOG.md` for changes to unit tests or documentation.
+  - Try building your changes locally. See [building from source][build] for instructions.
+- [Create a pull request][github-pr-create] to merge changes into the PSRule `master` branch.
+  - If you are _ready_ for your changes to be reviewed create a _pull request_.
+  - If you are _not ready_ for your changes to be reviewed, create a _draft pull request_.
+  - An continuous integration (CI) process will automatically build your changes.
+    - You changes must build successfully to be merged.
+    - If you have any build errors, push new commits to your branch.
+    - Avoid using forced pushes or squashing changes while in review, as this makes reviewing your changes harder.

+## 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`.
+
+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 v2.1 is required. .NET Core will not be automatically downloaded and installed.
+To download and install .NET Core SDK see [Download .NET Core 2.1](https://dotnet.microsoft.com/download/dotnet-core/2.1).
