+Why does AppVeyor say "Project not found or access denied" when opening a build?
+================================================================================
+
+This means you're not signed into AppVeyor. Follow these steps carefully:
+
+1. Click "SIGN IN" link in upper right corner
+2. Click the blue "GitHub" button under "Login with your developer account" on the left
+3. Click the green "Authorize Application" button in the pop-up from GitHub
+4. Click the "- select account -" menu and choose "PowerShell" (**not** your user)
+5. Click the blue "GitHub" button below the menu
+6. Go back to the original link you followed to AppVeyor and click it again
+
+You should now be signed into AppVeyor and able to access our builds.
