-A function app includes all of the files and folders in the `wwwroot` directory. A .zip file deployment includes the contents of the `wwwroot` directory, but not the directory itself. When deploying a C# class library project, you must include the compiled library files and dependencies in a `bin` subfolder in your .zip package.

+A zip deployment process extracts the zip archive's files and folders in the `wwwroot` directory. If you include the parent directory when creating the archive, the system will not find the files it expects to see in `wwwroot`.

+#### Deployment payload
+
+Many of the deployment methods make use of a zip archive. If you are creating the zip archive yourself, it must follow the structure outlined in this section. If it does not, your app may experience errors at startup.
+
+The deployment payload should match the output of a `dotnet publish` command, though without the enclosing parent folder. The zip archive should be made from the following files:
+
+- `.azurefunctions/`
+- `extensions.json`
+- `functions.metadata`
+- `host.json`
+- `worker.config.json`
+- Your project executable (a console app)
+- Other supporting files and directories peer to that executable
+
+These files are generated by the build process, and they are not meant to be edited directly.
+
+When preparing a zip archive for deployment, you should only compress the contents of the output directory, not the enclosing directory itself. When the archive is extracted into the current working directory, the files listed above need to be be immediately visible.

 ### Deployment requirements
 
 There are a few requirements for running .NET functions in the isolated worker model in Azure, depending on the operating system:

+The zip archive you deploy must contain all of the files needed to run your function app. You can manually create a zip archive from the contents of a Functions project folder using built-in .zip compression functionality or third-party tools.
