+General
+-------
+
+The external dependency package will not build in the snapcraft
+vm. The path of least resistance is to copy it to the root of the
+(original) workspace before running the prep script.
+
+Snapcraft has mount issues except under /home. Run the prep script and
+copy the entire directory (including the .tgz file) under
+/home/yourself.
+
+Run the prep script
+-------------------
+
+```
+ $ cd <vpp-workspace>/extras/snap
+ $ ./prep
+```
+
+Copy data to /home (if necessary)
+
+```
+ $ mkdir /home/xxx
+ $ cd <vpp-workspace>/extras/snap
+ $ cp * /home/xxx
+
+Set snapcraft environment variables
+-----------------------------------
+
+Minimum requirements:
+
+```
+ SNAPCRAFT_BUILD_ENVIRONMENT_MEMORY=16G
+ SNAPCRAFT_BUILD_ENVIRONMENT_DISK=32G
+```
+
+Optional:
+
+```
+ SNAPCRAFT_BUILD_ENVIRONMENT_CPU=8
+ SNAPCRAFT_ENABLE_DEVELOPER_DEBUG=yes
+```
+
+Run snapcraft
+-------------
+
+With luck, simply running snapcraft will produce the snap
+
+```
+ $ <environment-variable-settings> snapcraft [--debug]
+```
+
+Rerunning snapcraft phases
+--------------------------
+
+Here's how to (re)run individual phases, to avoid starting from
+scratch N times in case of errors:
+
+```
+ snapcraft pull [<part-name>]
+ snapcraft build [<part-name>]
+ snapcraft stage [<part-name>]
+ snapcraft prime [<part-name>]
+ snapcraft snap or snapcraft
+```
+
+Restart without rebuilding VM
+-----------------------------
+
+To restart from scratch without rebuilding the VM:
+
+```
+ snapcraft clean vpp
+```
+
+Delete (all) snapcraft VMs
+--------------------------
+
+```
+ for vm in $(multipass list | awk '{print $1}' | grep ^snapcraft-); do
+ multipass delete $vm --purge
+ done
+```
