 ## Setup
 
-### Option 1: Using Xcode
+### Option 1: Using XcodeGen (Recommended)
+
+1. Install XcodeGen if you haven't already:
+
+   ```bash
+   brew install xcodegen
+   ```
+
+2. Generate the Xcode project:
 
    ```bash
    cd bitchat
+   xcodegen generate
+   ```
+
+3. Open the generated project:
+   ```bash
    open bitchat.xcodeproj
    ```
 
-   To run on a device there're a few steps to prepare the code:
+### Option 2: Using Swift Package Manager
-   - Clone the local configs: `cp Configs/Local.xcconfig.example Configs/Local.xcconfig`
-   - Add your Developer Team ID into the newly created `Configs/Local.xcconfig`
-      - Bundle ID would be set to `chat.bitchat.<team_id>` (unless you set to something else)
-   - Entitlements need to be updated manually (TODO: Automate):
-      - Search and replace `group.chat.bitchat` with `group.<your_bundle_id>` (e.g. `group.chat.bitchat.ABC123`)
 
-### Option 2: Using `just`
+1. Open the project in Xcode:
 
    ```bash
-   brew install just
+   cd bitchat
+   open Package.swift
    ```
 
+2. Select your target device and run
+
+### Option 3: Manual Xcode Project
+
+1. Open Xcode and create a new iOS/macOS App
+2. Copy all Swift files from the `bitchat` directory into your project
+3. Update Info.plist with Bluetooth permissions
+4. Set deployment target to iOS 16.0 / macOS 13.0
+
+### Option 4: just
+
 Want to try this on macos: `just run` will set it up and run from source.
 Run `just clean` afterwards to restore things to original state for mobile app building and development.
