@@ -5,6 +5,12 @@ The main component is Pool type. It is a virtual connection to the network
 and provides methods for executing operations on the server. It also supports
 a weighted random selection of the underlying client to make requests.
 
+Pool has an auto-session mechanism for object operations. It is enabled by default.
+The mechanism allows to manipulate objects like upload, download, delete, etc, without explicit session passing.
+This behavior may be disabled per request by calling IgnoreSession() on the appropriate Prm* argument.
+Note that if auto-session is disabled, the user MUST provide the appropriate session manually for PUT and DELETE object operations.
+The user may provide session, for another object operations.

 Create pool instance with 3 nodes connection.
 This InitParameters will make pool use 192.168.130.71 node while it is healthy. Otherwise, it will make the pool use
 192.168.130.72 for 90% of requests and 192.168.130.73 for remaining 10%.
