+# Welcome
+
+SikevaDB is a Simple KEy VAlue DataBase.
+
+Features:
+* double key value
+* single session only
+* connector to file persistence
+* connector to SQL persistence
+
+Why build a single session database? Because, in so many cases, I need a single session only in my application.
+
+Actually, the following backends are supported:
+* file system
+* MySQL Database
+* HSQL Database
+
+# LICENSE
+
+SikevaDB is released under the GNU AGPL license. Enjoy!
