 ### What is checked
 
-The build system scans for `package.json` and `package-lock.json` files in your project directory. These files should not exist in the project root or subdirectories (with one exception).
+The build system scans for `package.json` and `package-lock.json` files in your project directory.
+
+Rules:
+
+- **ELECTRON001**: `package.json` / `package-lock.json` must not exist in the project directory or subdirectories
+  - Exception: `ElectronHostHook` folder is allowed
+  - Note: a **root** `package.json` is **excluded** from `ELECTRON001` and validated by `ELECTRON008` / `ELECTRON009`
+
+- **ELECTRON008**: If a root `package.json` exists, it must **not** contain electron-related dependencies or configuration.
+
+- **ELECTRON009**: If a root `package.json` exists, it must **not** be configured to be copied to output/publish (for example via `CopyToOutputDirectory` / `CopyToPublishDirectory` metadata)
 
 ### Why this matters
 
-In previous versions of Electron.NET, a `package.json` file was required in the project. The new version generates this file automatically from MSBuild properties defined in your `.csproj` file.
+Electron.NET generates its Electron-related `package.json` during publishing based on MSBuild properties. A user-maintained Electron-related `package.json` can conflict with that process.
+
+Also, ensuring the root `package.json` is not copied prevents accidentally shipping it with the published app.
 
 ### Exception
 
-A `package.json` file **is allowed** in the `ElectronHostHook` folder if you're using custom host hooks. This is the only valid location for a manually maintained package.json.
+A `package.json` / `package-lock.json` file **is allowed** in the `ElectronHostHook` folder if you're using custom host hooks.
 
 ### How to fix
 
+If you have an Electron-related `package.json` from older Electron.NET versions:
+
 1. **Open your project's `.csproj` file**
 2. **Add the required properties** to a PropertyGroup with the label `ElectronNetCommon`:

+### Preload Script
+
+If you require the use of a [preload script](https://www.electronjs.org/docs/latest/tutorial/tutorial-preload), you can specify the file path of the script when creating a new window like so:
+
+```csharp
+WebPreferences wp = new WebPreferences();
+wp.Preload = "path/to/preload.js";
+BrowserWindowOptions browserWindowOptions = new BrowserWindowOptions
+{
+    WebPreferences = wp
+};
+```
+
+> [!IMPORTANT]
+> When using a preload script _AND_ running a Blazor app, `IsRunningBlazor` must be set to `false` (or removed) and the following lines must be added to the preload script:
+> ```js
+> global.process = undefined;
+> global.module = undefined;
+> ```
