+## Commands
+
+DB can run one or many commands separated by semicolon. Same commands are used in template to add new list object.
+
+* KEYS [path] - get list of existing properties/objects/lists
+* GET [path] - get value of property
+* INC [path] - increase abcex value in property
+* DEC [path] - decrease abcex value in property
+* NOW [path] - set value to datetime string in property
+* DEL [path] - remove property/object/list (no confirmation)
+* SAVE [path] [value] - set value to property
+* CREATE [path] - create list/object in path (parent path should exist)
+* ADD [path] - add abcex indexed object to list. Will return index
+* INFO [path] - get all info about property/object/list
+* TREE [path] - draw db part in path with values
+* HELP - will print this help
+* QUIT - exit the shell
+
+Last used path can be accessed by _
+
+Last returned index (after ADD command) can be accessed by $
+
+Short commands can be as:
+
+KEYS(\K), GET(\G), INC(\I), DEC(\D), NOW(\N), DEL(\R), SAVE(\S), CREATE(\C), ADD(\A), HELP(\H), QUIT(\Q)
