+
+## Details
+
+Oracle Linux is distributed as an [ISO image](https://en.wikipedia.org/wiki/ISO_image), which is a binary representation of the files and contents for installing the operating system. An Oracle Linux installation requires that you need to create an installation media from the ISO image.
+
+As the official documentation shows, Oracle's supported method for creating the installation media is by using the `dd` command. However, you can choose any preferred third party utility, such as Balena Etcher or Rufus.
+
+This tutorial focuses on using Ventoy to create installation media on a USB drive. If you are using macOS, follow the instructions in [our tutorial for Fedora Media Writer](https://docs.oracle.com/en/learn/usb-media/) instead.
+
+Ventoy is a utility that creates a bootable USB device, but unlike other installation media creation tools that copy the contents of one ISO image onto one USB device, Ventoy installs a custom bootloader onto that USB media and then creates a blank partition onto which you can copy one or more ISO image files.
+
+This approach means that, instead of needing three separate USB devices for each ISO image, you can use the same physical USB device to run install media for Oracle Linux 7, Oracle Linux 8, and Oracle Linux 9. Also, whenever Oracle releases a new ISO image, you can copy it onto your existing USB device instead of creating new install media for Oracle Linux on another USB device. You can also continue to use your USB flash drive to back up files and copy files between machines.
+
+## Objectives
+
+At the end of this tutorial, you should be able to do the following:
+
+- Download one or more Oracle Linux ISO images.
+- Format the USB drive with the correct file system.
+- Download, install, and run Ventoy.
+- Copy ISO image files to the USB drive.
+
+## Prerequisites
+
+- Any system that is running Windows 10 or newer, or a recent Linux distribution.
+- A secure USB flash drive or external hard drive.

+
+## Details
+
+Creating your own customized Oracle OS Management Hub software sources is powerful. Using the OCI console, you can apply filters to limit the set of packages and modules to just those you want and create a custom software source or versioned custom software source. Sometimes, using the filters to generate a lengthy set of packages at just the patch level you want is impractical. There is a faster and more streamlined way to create custom and versioned custom software sources using the OCI CLI. OS Management Hub integrates fully with the OCI CLI and the OCI API/SDK, so you can programmatically interact with the service. In this tutorial, you'll learn how to take a reference package list from an Oracle Linux instance and use the OCI CLI to create a custom or versioned custom software source in OS Management Hub.

+### Objectives
+
+In this tutorial, you will learn how to:
+
+- Create Oracle OS Management Hub custom and versioned custom software sources for Oracle Linux from a reference package list using the OCI CLI
+
+### Prerequisites
+
+- Access to your OCI tenancy
+- [OCI Privileges](https://docs.oracle.com/iaas/osmh/doc/getstarted.htm#required-iam-policies) to read OS Management Hub managed instances and create software sources in OCI
+- [OCI API Signing Key](https://docs.oracle.com/iaas/Content/API/Concepts/apisigningkey.htm) is created and your ~/.oci/config is setup
+- [OCI CLI v3.29.2](https://docs.oracle.com/iaas/Content/API/SDKDocs/cliinstall.htm#Quickstart) or newer installed (check with oci --version)
+- A reference Oracle Linux 7, 8, or 9 system and its OCID (if managed by OS Management Hub)
+- The OCID of your OCI tenancy
+- Access to the internet
