+         The small Android app ghini.pocket was added to the Ghini family
+         while a Ghini programmer was here in Quito.  It helps us take a
+         snapshot of the database in our pocket while walking in the garden,
+         but it also allows for a very swift inventory procedure.
+
+  .. admonition:: Inventory procedure
+     :class: toggle
+
+        We start ghini.pocket, we write down the name of the location where
+        we will be conducting the inventory, for example (INV 1) for
+        greenhouse 1.  We enter (type or scan if the plant has bar code or
+        QR code) the accession code and we look it up in ghini.pocket.
+
+        A side effect of performing the search is that ghini.pocket writes
+        the date with time, location and the code looked for in a text file
+        that can later be imported into the database.
+
+        For a greenhouse with around 1000 plants our estimates suggest you
+        will need two days, working at relaxed pace, from 8:00 am to 5:00
+        pm.
+
+        After having imported the file generated by ghini.pocket, it is easy
+        to reveal which plants are missing. For example: If we did the
+        inventory of the INV3 from 4 to 5 September, this is the
+        corresponding search::
+
+          plant where location.code = 'INV3' and not notes.note like '2017090%'
+
+        All of these plants can be marked as dead, or lost, according to
+        garden policy.

+         Our protocol includes one more detail intended to visually
+         highlight plants that need the attention of a taxonomist.

+         .. image:: images/taxonomic_alert.png
+
+         A plant that only appears in our data base identified at family
+         level or that wasn't yet the database receives a visual signal
+         (e.g.: a wooden or plastic stick, for ice cream or french fries), to
+         highlight that it is not identified. In this way the taxonomist in
+         charge, when making a tour of the greenhouse can quickly spot them
+         and possibly proceed to add their identification in the database.
