+This article aims at guiding you, an end-user of your company's web app, to scan documents using Dynamic Web TWAIN.
+
+## Install Service
+
+When you visit your company's web app and want to scan for the first time, you may be prompted to install Dynamic Web TWAIN if your IT does not have it installed. Please download the service installer and install it on your device. It is needed to communicate between the scanners and the web app.
+
+Service Installation Dialog:
+
+![service installation dialog](/assets/imgs/install-dialog.png)
+
+If you still see the dialog after installation, try enabling [access to apps on your device](#allow-access-to-local-apps) and checking the [list of possible reasons](/_articles/faq/service-prompting-to-install-repeatedly.md).
+
+## Allow Access to Local Apps
+
+In latest browsers, you also need to grant access to apps on your device to make proper scanning.
+
+When it is asking for permission, please click "Allow".

+
+If you accidentally block the access, you can reset it as shown in the following dialog.

+
+The UI may vary according to different browsers and browser versions.
+
+## Perform Scanning
+
+Now, visit your app and try to scan documents. Here, we are using Dynamsoft's [online demo](https://demo.dynamsoft.com/web-twain/) for illustration.

+
+If it does not detect any scanners, make sure that you have installed the driver. You can find the driver from scanner manufacturer's support site.
