 ## Best Practices
+### ClickOnce
+Generally you will want to sign an entire package and all its contents i.e. the deployment manifest (`.application` or `.vsto`), application manifest (`.exe.manifest` or `.dll.manifest`) and the underlying `.exe` and `.dll` files themselves. To do this, ensure that the entire contents of the package are available (i.e. the whole `publish` folder from your build) and pass the deployment manifest (`.application` or `.vsto`) as the file to sign - the rest of the files will be detected and signed in the proper order automatically.
+
+In the example below, it is only necessary to pass `ClickOnceApp.application` and `setup.exe` to the Trusted Signing Action. The remaining "Application Files" will be signed automatically.
+
+```txt
+C:\TEST\ASSETS\SAMPLE-FILES\CLICKONCE
+│   ClickOnceApp.application
+│   setup.exe
+└───Application Files
+    └───ClickOnceApp_1_0_0_0
+            ClickOnceApp.deps.json.deploy
+            ClickOnceApp.dll.deploy
+            ClickOnceApp.dll.manifest
+            ClickOnceApp.exe.deploy
+            ClickOnceApp.runtimeconfig.json.deploy
+            Launcher.exe.deploy
+```
+
+The following inputs are ignored when signing ClickOnce files:
+- `append-signature`
+- `generate-digest-path`
+- `generate-digest-xml`
+- `ingest-digest-path`
+- `sign-digest`
+- `generate-page-hashes`
+- `suppress-page-hashes`
+- `generate-pkcs7`
+- `pkcs7-options`
+- `pkcs7-oid`
+- `enhanced-key-usage`
+
 ### Timestamping
 The files must be signed with timestamping enabled in order for the signatures to be valid for longer than 3 days. It is recommended to use the Trusted Signing timestamp server:
