+# Dynamic Web TWAIN Sample: Ruby on Rails
+The sample demonstrates how to integrate Dynamic Web TWAIN into Ruby on Rails project.
+
+## Installation
+- [Dynamic Web TWAIN 17.0](https://www.dynamsoft.com/web-twain/downloads)
+- Ruby 2.5.1
+
+    ```bash
+    sudo apt install ruby-full
+    ```
+- Sqlite3 3.22.0

+
+- Rails 6.1.3.2
+
+    ```bash
+    gem install rails
+    ```
+
+## Deployment
+1. Copy `Resources` folder from `<Dynamic Web TWAIN installation directory>` to `public` folder.   
+2. Get a [valid license](https://www.dynamsoft.com/customer/license/trialLicense/?product=dcv&package=cross-platform) and set the license in `app/views/twainscanning/home.html.erb`:
+
+    ```js
+    Dynamsoft.DWT.ProductKey = "";
+    ``` 
+3. Run the project:
+
+    ```bash
+    bundle install
