 ## Install Ruby on Rails
-In this section, you will learn how to install Ruby, Rails, and related tools (like rbenv and Bundler) on a SUSE Arm-based virtual machine. This guide will also cover installing the necessary dependencies to compile Ruby and run Rails applications smoothly.
-
+In this section, you’ll install Ruby, Rails, and essential supporting tools on a SUSE Arm64 your Google Cloud C4A instance running SUSE Enterprise Linux. The steps ensure your environment is ready to build, deploy, and optimize Ruby on Rails applications on Arm-based infrastructure.
 
 ### Update System Packages
-Updates all system packages to the latest versions to ensure stability and security.
+Before installation, update all existing system packages. This ensures you have the latest security patches, compiler toolchains, and library versions compatible with Ruby.
 
 ```console
 sudo zypper update
 ```
 
 ### Install Required Dependencies
-These packages are essential for compiling Ruby and its native extensions.
+Before installing Ruby, you need to install several core development libraries and tools. These packages ensure that Ruby and its native extensions compile and run correctly on your SUSE Arm64 environment.
 
 ```console
 sudo zypper install git curl gcc make patch libyaml-devel libffi-devel libopenssl-devel readline-devel zlib-devel gdbm-devel bzip2 bzip2-devel
 ```
 
 ### Install rbenv
-**rbenv** is a lightweight Ruby version manager that allows multiple Ruby versions on the same system.
+`rbenv` is a lightweight Ruby version manager that enables you to install and manage multiple Ruby versions on the same system. This is particularly useful for developers running different Rails applications that require specific Ruby versions.
 
 ```console
 git clone https://github.com/rbenv/rbenv.git ~/.rbenv
 echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
 echo 'eval "$(rbenv init -)"' >> ~/.bashrc
 source ~/.bashrc
 ```
-- Clones the rbenv repository to manage Ruby versions
-- Updates `PATH` so your shell can find rbenv
-- Initializes rbenv in your shell session
+With these steps you have cloned the `rbenv` repository to manage Ruby versions. Your `PATH` is updated so your shell can find rbenv. It then initializes rbenv in your shell session. 
 
 ### Install ruby-build Plugin
-**ruby-build** is an rbenv plugin that provides the `rbenv install` command to compile and install different Ruby versions from source.
+`ruby-build` is an rbenv plugin that adds the `rbenv` install command, allowing you to compile and install specific Ruby versions from source. 
 
 ```console
 git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build
 ```
 
 ### Install Ruby
-Installs Ruby and sets it as the default version for your environment.
+Now that `rbenv` and `ruby-build` are set up, you can install Ruby and configure it as your system’s default version. This step compiles Ruby from source:
 
 ```console
 rbenv install 3.4.6
 rbenv global 3.4.6
 ruby -v
 ```
-- Installs Ruby 3.4.6 from source
+With these commands you have: 
+- Installed Ruby 3.4.6 from source
 - Sets it as the default Ruby version for your user
 - `ruby -v` verifies the installed Ruby version

-Ruby 3.4.0 introduced significant performance enhancements, notably improvements to YJIT (Yet Another Ruby JIT), a Ruby just-in-time compiler. These enhancements are particularly beneficial for Arm architectures, as YJIT has been optimized to deliver better performance on such platforms. To leverage these improvements, it is recommended that you upgrade to Ruby 3.4.0 or later.

 ### Install Bundler
-**Bundler** manages Ruby project dependencies and ensures consistent gem versions across environments.
+Bundler is Ruby’s dependency management tool. It ensures that all required gems (libraries) for your Rails application are installed and consistent across development, test, and production environments.
+
+Install Bundler globally:
 
 ```console
 gem install bundler
 ```
+This command installs Bundler for the active Ruby version managed by rbenv.
 
 ### Install Rails
-Rails is a full-stack web application framework for Ruby that simplifies building database-backed web applications with convention over configuration.
+Rails is a full-stack web framework built in Ruby, designed for rapid development using convention over configuration principles.
+Installing Rails on your SUSE Arm64 VM enables you to build and deploy web applications natively on Google Cloud Axion (C4A) processors.
 
 ```console
 gem install rails
-rails -v
 ```
-- Installs the Rails framework
-- `rails -v` verifies the installed Rails version
