+# Class: profile::yum::epel
+#
+# This class manages the puppet7 yum repository for the system.
+#
+# Parameters:
+# -----------
+# - $baseurl: The base URL for the puppet7 yum repository. This should be the root
+#             URL of your puppet7 mirror server.
+#
+# Actions:
+# --------
+# - Checks the OS release version.
+#
+# - If the release version is 7, 8, or 9, it sets up the 'puppet7' yum repository 
+#   and installs the puppet7 release RPM from the provided baseurl.
+#
+# - If the release version is not supported, it raises an error.
+#
+# - The repo configuration includes the baseurl parameterized with the OS
+#   release version and architecture, and specifies the GPG key.
+#
+# Example usage:
+# --------------
+# To use this class with the default parameters:
+#   include profile::yum::puppet7
+#
+# To specify a custom base URL:
+#   class { 'profile::yum::puppet7':
+#     baseurl => 'http://mylocalmirror.com/yum',
