+# Debugging Installs
+
+The following tips will help you to debug the installation of an Squirrel app.
+
+## Simulating an Install and First Run
+
+If the install of your application doesn't seem to be working, you can explore the behavior by executing the install steps from the command line:
+
+~~~ps
+C:\user\AppData\Local\MyApp> Update.exe --squirrel-install 1.0.0
+C:\user\AppData\Local\MyApp> Update.exe --squirrel-firstrun
+~~~
+
+The first cmd should create some shortcuts then immediately exit, then the 2nd one should start your app ([source](https://github.com/Squirrel/Squirrel.Windows/issues/525))
