+## Packaging and Installing Pantheon CMD on RHEL and Fedora
 After you update Pantheon CMD and test the changes, build an RPM-based package for the script to be installed on systems that use *yum* or *dnf*.
 
 * Prerequisites:
     * A user has registered their SSH keys with GitHub.
 
-1. Install the `svn` and `rpmbuild` packages on your system:
-   ```shell
-   # on RHEL
-   $ sudo yum install subversion
-   $ sudo yum install rpm-build
-
-   # on Fedora
-   $ sudo dnf install subversion
-   $ sudo dnf install rpm-build
-   ```  
-2. Clone this repository.
+1. Clone this repository.
    ```shell
    $ git clone [email protected]:redhataccess/pantheon-cmd.git
    ```
-3. Open *./build/pantheon-cmd.spec*.
-4. Increment the value of the *Release* number.
-    As an example, `Release:   1%{?dist}` increments the version of the build to `1.0.1`, where `{?dist}` identifies of your Linux distribution.
-5. Run the build script:
-   ```shell
-   $ sh make.sh 1.0
-   ```
-   As a result, the `build/pantheon-cmd-1.0-X.<your-distribution-and-version>.noarch.rpm` file is generated in the root of the repository. This file will be used in the following step.
-
-## Installing Pantheon CMD
-
-Install Pantheon CMD on a local system.
-
-## Installing Pantheon CMD on RHEL and Fedora
-
-Install the RPM and all Ruby gem dependencies.
-
-1. Install the RPM:
-   ```shell
-   $ sudo dnf localinstall build/pantheon-cmd-1.0-X.el8.noarch.rpm
-   ```
-   Note that your `rpm` filename might differ based on your Linux distribution.
-   * Example:
-        *  `el8` for RHEL 8
-        *  `fc34` for Fedora 34
-
-2. Install Ruby gem dependencies:
+2. Navigate to the `pantheon-cmd` directory:
+    ```shell
+    $ cd pantheon-cmd
+    ```
+3. Run the `linux-cmd-intallation.sh` packaging and installation script:
    ```shell
-   $ sudo gem install asciidoctor concurrent-ruby haml tilt
+   $ sh linux-cmd-intallation.sh
    ```
 
 The script is installed on your local machine.
