 ## Current workflow
 For a sig working on a package in git.centos.org, the following workflow is
 recommended:
 
     # In this example a member of the virt sig would like to scratch-build a2ps on EL6
-    $ centpkg clone -b virt6 a2ps
+    $ centpkg-sig clone -b virt6 a2ps
     $ cd a2ps
-    $ centpkg build --srpm --scratch 
+    $ centpkg-sig build --srpm --scratch 
 
     # Tagged builds can be done also 
-    $ centpkg build --srpm
+    $ centpkg-sig build --srpm
