+POS Cache
++++++++++
+
+This module enables a cache for the products in the pos configs. Each POS Config has his own Cache.
+
+The Cache is updated every hour by a cron.
+
+============
+Compute user
+============
+
+As it's a bad practice to use the admin in a multi-company configuration, a field permit to force a user to compute
+the cache. A badly chosen user can result in wrong taxes in POS in a multi-company environment.
