 #### Note for Apple Silicon users
+If you own a Mac laptop with Apple Silicon, follow these additional steps for proper setup:
 
-If you own a Mac laptop with Apple Silicon, you need to run some different commands to install and run cocoapods.
+1. Install Rosetta 2 if you haven't already:
+```sh
+softwareupdate --install-rosetta
+```
+
+2. Install Bundler using Rosetta:
+```sh
+arch -x86_64 sudo gem install bundler
+```
 
-- `sudo arch -x86_64 gem install ffi`: this installs the `ffi` package to load dynamically-linked libraries.
-- `arch -x86_64 pod install`: this run `pod install` with the right architecture.
+3. Install the required packages:
+```sh
+# Install ffi package to load dynamically-linked libraries
+sudo arch -x86_64 gem install ffi
+
+# Install CocoaPods dependencies using the correct architecture
+arch -x86_64 bundle install
+
+# Install pods with the correct architecture
+arch -x86_64 pod install
+```
+
+If you encounter build issues, you may need to clean and rebuild:
+```sh
+# Clean existing builds
+yarn clean-ios
+
+# Remove and reinstall pods
+arch -x86_64 bundle exec pod deintegrate
+arch -x86_64 bundle exec pod install
+```
+
+Then proceed with opening the workspace in Xcode:
+```sh
+open RNTesterPods.xcworkspace
+```
