 An entity is defined as follow
+
     [Entity]
 		#attr1 (*)
 		attr2 (*)
+
 with (\*) = optional SQL indications, and # denoting a (part of) a key.
 
 A relationship is defined in this way
+
     {Relation}
 		Entity C1
 		Entity2 C2
     --
 		attr1 (*)
 		attr2 (*)
+
 where attributes are optional, and C1 (resp. C2) = cardinality for entity 1 (resp. 2).
 Defining relationships with more than two attributes is easy: just add entities.
 Cardinality dictionary:
  * \* = 0..n
- * + = 1..n
+ * \+ = 1..n
  * 1 = 1..1
  * ? = 0..1
 
 To mark a weak entity, just surround its name by extra-brackets
+
 	[[WeakEntity]]
+
 In the same way, a weak relation can be written
+
 	{{WeakRelation}}
+
 The syntax for these two last is then the same as in the non-weak versions.
 
 To indicate an inheritance relation, proceed as follow
+
     is_a
 		Animal Cat Fish
 		Planet Mars Venus
 
-Finally, blocks must be separated by new lines. For a usage example, see example.html
+Finally, blocks must be separated by new lines. For a usage example, see example.html (it should render as seen in example.svg)
 
 Note that the "drawMcd" method can take a second argument, which indicates the type of graph.
  * "bubble" draws the standard graph, as seen [here](https://en.wikipedia.org/wiki/Entity%E2%80%93relationship_model#/media/File:ER_Diagram_MMORPG.png) for example
  * "compact" (default) use the same box for an entity and its attributes
