+= Creating ULN repositories
+
+You can synchronize content from Oracle Unbreakable Linux Network (ULN) to {Project}.
+There are two main differences compared to generic Yum content:
+
+* The *Upstream URL* field consists of a protocol prefix `uln://` and an `ULN Channel Label`, for example, `ol7_x86_64_MySQL80_community`.
+Combined, `uln://ol7_x86_64_MySQL80_community` is a valid upstream URL for a Yum repository.
+* Authentication against the repository through an *Upstream Username* and *Upstream Password* is mandatory.
+This requires your single sign-on user name and password of your Oracle account to be saved on your {Project}.
+
+To obtain a list of available ULN channel labels, log in to https://linux.oracle.com/[Oracle Unbreakable Linux Network].
+Navigate to the *channels* tab and select an operating system release version and architecture.
+Copy the required *ULN Channel Label* from the list of available content.
+
+Adding ULN repositories is different compared to Yum repositories for {client-os}, for example, `\https://yum.oracle.com/oracle-linux-9.html`, which you can add as Yum-type content.
+For more information, see xref:Adding_Custom_RPM_Repositories_{context}[Adding RPM repositories].

+[IMPORTANT]
+====
+{Team} recommends that you limit the download concurrency to `1` for ULN content to avoid synchronization failures.
+You can use Hammer CLI to configure your ULN repository on {Project}:
+
+[options="nowrap", subs="+quotes,verbatim,attributes"]
+----
+$ hammer repository update \
+--download-concurrency 1 \
+--id _My_ULN_Repository_ID_
+----
+
+Note that this setting is not exposed in the {ProjectWebUI}.
