+# 📌 Bitbucket Pipelines Guide
+
+## 📖 Overview
+This project uses **Bitbucket Pipelines** for automating builds, deployments
+Bitbucket Pipelines is configured with firebase to:  
+
+- **Auto-trigger builds** when pushing code to `develop`, `staging`, or `production`.  
+- **Support manual execution** using **custom pipelines** for specific tasks.  
+
+---
+
+## 🚀 Automatic Branch-Based Pipelines
+When code is pushed to a branch (`develop`, `staging`, `production`), Bitbucket Pipelines will execute different tasks depending on what has changed.
+
+### 🔹 Conditional Builds
+```yaml
+condition:
+  changesets:
+    includePaths:
+      - "ios/**"
+      - "android/**"
+      - "package.json"
+      - "*.env.*"
+      ...
+```
+ •	If these files change, a full build (Xcode & Android) is triggered.
+
+### 🔹 Pipeline Execution Flow
+
+| Branch      | Condition                                         | Action                                |
+|------------|-------------------------------------------------|---------------------------------------|
+| `develop`  | Code changes in `ios/`, `android/`, `package.json`, `.env.*` | Full Build & Upload to TestFlight(iOS)    |
+| `staging`  | Always builds                                    | Full Build & Upload                  |
+| `production` | Always builds                                  | Full Build & Upload                  |
+
+
+## 🛠️ Running Pipelines in Bitbucket
+
+### 🔹 How to Trigger a Pipeline Manually
+1. Open **Bitbucket** → Navigate to your repository.
+2. Click **Pipelines** (left menu).
+3. Click **Run Pipeline**.
+4. Select a **Branch** (e.g., `develop`).
+5. Choose a **Custom Pipeline** from the dropdown:
+   - **`buildDev`** → Manually build development version  
+   - **`buildStaging`** → Manually build staging version  
+   - **`buildProduction`** → Manually build production version  
+6. Click **Run**.
+
+# 🔄 Environment Variables in Bitbucket Pipelines
+
+Bitbucket Pipelines relies on **environment variables** to securely manage sensitive data like API keys, App IDs, and credentials. This guide explains how to update and manage these variables effectively.
+
+---
+## 📌 Environment Variables Used in Bitbucket Pipelines
+
+| Variable Name           | Description                                      | Example Value             |
+|-------------------------|--------------------------------------------------|---------------------------|
+| `BITBUCKET_BUILD_NUMBER` | Auto-generated build number for tracking.       | `123`                     |
+| `PROJECT_NAME`         | The name of your React Native project.           | `MyApp`                   |
+| `APP_ID`               | The application identifier (package name).       | `com.example.myapp`       |
+| `KEYCHAIN_PASSWORD`    | **macOS Keychain password** for signing iOS apps. | `"my-secure-password"`    |
+
+---
+
+## 🚀 Updating Variables in Fastlane for Bitbucket
+
+If you update any **environment variables**, make sure **Fastlane** picks up the changes by modifying your `.env` files.
+
+### 🔹 Updating `.env` File
+1. Navigate to the project root.
+2. Open or create `.env.development`, `.env.staging`, `.env.production`.
+3. Update the variables as needed:
+   ```sh
+   APP_ID=com.example.myapp
+   PROJECT_NAME=MyApp
