+<a name='Overview_Command'></a>
+## Command
+Since it is not possible to make structural modification on an Entity in a multithreading  context, the EntityCommandRecorder type is provided to adress this short-coming.
+It is possible de record command on entities in a thread-safe way to later execute them when those structural modifications are safe to do.
+```C#
+// This creates an expandable recorder with a default capacity of 1Ko
+EntityCommandRecorder recorder = new EntityCommandRecorder();
+
+// This creates a fixed capacity recorder of 512Ko
+EntityCommandRecorder recorder = new EntityCommandRecorder(512);
+
+// This creates an expandable recorder with a default capacity of .5Ko which can have a maximum capacity of 2Ko
+EntityCommandRecorder recorder = new EntityCommandRecorder(512, 2048);
+```
+
+Note that a fixed capacity EntityCommandRecorder (or one which has expanded to its max capacity) has better performance.
+When needed, an expandable EntityCommandRecorder will double its capacity so it is prefered to use a power of 2 as default capacity.
+
+```C#
+// Create a new Entity defered and give an EntityRecord to record commands on it
+EntityRecord newRecord = recorder.CreateEntity();
+
+// Register an Entity and give an EntityRecord to record commands on it
+EntityRecord record = recorder.Record(entity);
+
+// EntityRecord has the same API as Entity so all action expected are available to record as command this way
+newRecord.Set<bool>(true);
+record.SetAsParentOf(newRecord);
+
+// To execute all recorded commands
+recorder.Execute(world);
+```
