 Hotfixes
 --------
 
-TBD
+Attach to the base image first: 
+
+  # $HOTFIX is arbitrary; helps avoid copying and pasting alphanumeric IDs
+  $ docker run --name $HOTFIX -it taler_local/taler_base /bin/bash
+
+From inside the container, navigate to "/$REPO", issue
+"git pull" and install the software as usual.  Exit the
+container thereafter.
+
+Commit the container having the hotfix:
+
+  $ docker commit $HOTFIX
+
+That outputs a new ID ($RETVAL).  That is the ID of the
+modified image.  Tag it, to let other images use it to build:
+  
+  $ docker tag $RETVAL taler_local/taler_base:latest
+
+Now build all the images with docker-compose, as described
+in the 'How to run' section.
