+Zope standalone instance
+========================
+
+This recipe is useful to create standalone Zope instance independent from
+buildout tree.
+
+Specification
+=============
+
+This recipe shall provide safe instance creation and updating. It shall mix
+Zope level instance creation with ERP5 site bootstrap (erp5.recipe.zope2install
++ erp5.recipe.createsite). On update only filesystem will be *safely* updated
+without touch user produced data (mostly from ZODB).
+
+DISCLAIMER
+==========
+Until some stability will be met everything can change without any further
+notice, without backward compatibility, possibly with *removing* existing data
+produced by previous versions.
