+```()```
+It's an empty *node*, to indicate that there is a *node*, but it's not relevant for the query.
 
-**`(n)`** It's a *node* refered by the variable **n**, reusable in the query. It begins with lowercase and uses camelCase.
+```(n)```
+It's a *node* refered by the variable **n**, reusable in the query. It begins with lowercase and uses camelCase.
 
-**`(p:Person)`** You can add a *label* to your node, here **Person**. It's like a type / a class / a category. It begins with uppercase and uses camelCase.
+```(p:Person)```
+You can add a *label* to your node, here **Person**. It's like a type / a class / a category. It begins with uppercase and uses camelCase.
 
-**`(p:Person:Manager)`** A node can have many *labels*.
+```(p:Person:Manager)```
+A node can have many *labels*.
 
-**`(p:Person {name : 'Théo Gauchoux', age : 22})`** A node can have some *properties*, here **name** and **age**. It begins with lowercase and uses camelCase.
+```(p:Person {name : 'Théo Gauchoux', age : 22})```
+A node can have some *properties*, here **name** and **age**. It begins with lowercase and uses camelCase.
 
 The types allowed in properties :
-* Numeric
-* Boolean
-* String
-* List of previous primitive types
 
-**Warning : there isn't datetime property in Cypher ! You can use String with a specific pattern or a Numeric from a specific date.**

 Special hints

-* You can execute a Cypher script stored in a **.cql** file directly in Neo4j (it's an import). However, you can't have multiple statements in this file (separed by **;**).
-* Use the Neo4j shell to write Cypher, it's really awesome.
-* The Cypher will be the standard query language for all graph databases (known as **OpenCypher**).
