+    If you have to create tags for SCLs, see the note below as we have to consolidate tags into specific one for signing purpose. We'll eventually backport that into automation script later
+
+##### SCLs specific tags
+The Software Collection SIG has some specific requirements and pkgs that need to be tagged in buildroot and also tags being consolidated when processed for signing (all lands into *one* repository and not multiple ones, even if there quite some SCL tags.
+
+Example below that we need to do when we have a request for a new SCL , and let's assume that it's a RH collection.We have already created the tag as in the process above, but we'll need to tune these tags a little bit and let's so first declare some variables :
+
+```
+tag="sclo7-rh-redis6-rh"
+collection="rh-redis6"
+origin="rh" # can be sclo or rh, needed below
+koji add-group-pkg ${tag}-el7-build srpm-build scl-utils-build ${collection}-build
+koji add-group-pkg ${tag}-el7-build build scl-utils-build ${collection}-build
+
+for level in testing release ;  do
+  last_priority=$(koji taginfo sclo7-all-${origin}-${level}|tail -n 1 |awk '{print $1}')
+  koji add-tag-inheritance sclo7-all-${origin}-${level} ${tag}-${level}  --priority $(( $last_priority + 5 ))
+done
+
+```
+
+
 #### Modifying existing tags
 
 It's always possible to modify some existing tags through standard `koji` (or `cbs` alias) CLI calls.
