+### Doing faster partial deploys
+
+If you only change a tiny bit on the platform puppet recipes, you could achieve a
+*much* faster deploy specifying the resource tag you changed.
+i.e. you changed the way rsyslog config snippets for LEAP logfiles are created
+in `puppet/modules/leap/manifests/logfile.pp`. This `define` resource will get tagged
+automatically with `leap::logfile` and you can deploy the change with:
+
+ leap deploy *NODE* --fast --tags=leap::logfile
+
