+`@johnhaup/code-push-cli` is a Node.js application that allows users to interact with CodePush Server. The is a fork of the `/cli` folder from the [deprecated codepush repo](https://github.com/microsoft/code-push-server).
+
+Note that the cli prefix has been changed from `code-push-standalone` to `code-push`.
+
+The goal of this repo is to cleanup and extend the existing `code-push-standalone` cli while keeping it fully backwards-compatible with the existing [Code Push Server](https://github.com/microsoft/code-push-server/tree/main/api#codepush-server). If you're hosting a modified version of the server, this cli might not be compatible with your backend.
+
+PRs welcome!
 
 ## Installation
 
 ```bash
 npm install -g @johnhaup/code-push-cli
 ```
 
+## Local Development
+
+You can easily set up a mock server and test changes against it.
+If you're using VSCode and GitHub, follow these steps:
+
+#### Server
+
+1. Clone the [Code Push Server](https://github.com/microsoft/code-push-server/tree/main/api#codepush-server) repository to your local machine
+2. Copy the `.env.example` file to a new file named `.env` in the root directory:
+
+```bash
+cp .env.example .env
+```
+
+3. Create a [GitHub OAuth app](https://github.com/settings/developers)
+4. Update the following in your `.env`:
+
+```bash
+GITHUB_CLIENT_ID= # From your GitHub OAuth app
+GITHUB_CLIENT_SECRET= # From your GitHub OAuth app
+EMULATED=true
+```
+
+3. Install all necessary dependencies:
+
+```bash
+npm install
+```
+
+4. Compile the server code:
+
+```bash
+npm run build
+```
+
+5. Install [Azurite VSCode extension](https://marketplace.visualstudio.com/items?itemName=Azurite.azurite)
+6. Run `Azurite Start` from VSCode's command palette
+7. Run you local server:
+
+```bash
+npm run start:env
+```
+
+#### CLI
+
+Back in this repo, you can build the cli locally and run commands with the `npm run code-push` prefix:
+
+```bash
+# Build your changes
+npm run build
+
+# Interact with local server
+npm run code-push register
+npm run code-push login
+# etc
+```
+
 ## Getting started
 
 1. Create a [CodePush account](#account-creation) push using the CodePush CLI.
