+# Scale Out
+
+Bot Framework v4 bot Scale Out sample
+
+This bot has been created using [Bot Framework](https://dev.botframework.com), is shows how to use a custom storage solution that supports a deployment scaled out across multiple machines.
+
+The custom storage solution is implemented against memory for testing purposes and against Azure Blob Storage.  The sample shows how storage solutions with different policies can be implemented and integrated with the framework.  The solution makes use of the standard HTTP ETag/If-Match mechanisms commonly found on cloud storage technologies.
+
+## Prerequisites
+
+- [Node.js](https://nodejs.org) version 16.16.0 or higher
+
+    ```bash
+    # determine node version
+    node --version
+    ```
+- Update `.env` with required configuration settings
+  - MicrosoftAppId
+  - MicrosoftAppPassword
+  - ConnectionName
+
+## To try this sample
+
+- Clone the repository
+
+    ```bash
+    git clone https://github.com/microsoft/botbuilder-samples.git
+    ```
+
+- In a terminal, navigate to `samples/javascript_nodejs/42.scale-out`
+
+    ```bash
+    cd samples/javascript_nodejs/42.scale-out
+    ```
+
+- Install modules
+
+    ```bash
+    npm install
+    ```
+
+- Start the bot
+
+    ```bash
+    npm start
+    ```
+
+## Testing the bot using Bot Framework Emulator
+
+[Bot Framework Emulator](https://github.com/microsoft/botframework-emulator) is a desktop application that allows bot developers to test and debug their bots on localhost or running remotely through a tunnel.
+
+- Install the latest Bot Framework Emulator from [here](https://github.com/Microsoft/BotFramework-Emulator/releases)
+
+### Connect to the bot using Bot Framework Emulator
+
+- Launch Bot Framework Emulator
+- File -> Open Bot
+- Enter a Bot URL of `http://localhost:3978/api/messages`
+
