+Xtensive.Orm.BulkOperations
+===========================
+
+Summary
+-------
+The extension provides a set of IQueryable extension methods that are translated 
+to server-side UPDATE or DELETE commands.
+
+Prerequisites
+-------------
+DataObjects.Net 6.0.x (http://dataobjects.net)
+
+
+Examples of usage
+-----------------
+
+**Example #1**. Update primitive property with a constant value:
+
+```csharp
+  session.Query.All<Bar>()
+    .Where(a => a.Id == 1)
+    .Set(a => a.Count, 2)
+    Update();
+```
+
+**Example #2** Updating persistent property with expression, computed on server:
+
+```csharp
+  session.Query.All<Bar>()
+    .Where(a => a.Id==1)
+    .Set(a => a.Count, a => a.Description.Length)
+    .Update();
+```
+
+**Example #3**. Setting a reference to an entity that is already loaded into current Session
+
+```csharp
+  // Emulating entity loading
+  var bar = session.Query.Single<Bar>(1);
+
+  session.Query.All<Foo>()
+    .Where(a => a.Id == 2)
+    .Set(a => a.Bar, bar)
+    .Update();
+```
+
+**Example #4**. Setting a reference to an entity that is not loaded into Session, 1st way
+
+```csharp
+  session.Query.All<Foo>()
+    .Where(a => a.Id == 1)
+    .Set(a => a.Bar, a => Query.Single<Bar>(1))
+    .Update();
+```
+
+**Example #5**. Setting a reference to an entity that is not loaded into Session, 2nd way
+
+```csharp
+  session.Query.All<Foo>()
+    .Where(a => a.Id == 1)
+    .Set(a => a.Bar, a => Query.All<Bar>().Single(b => b.Name == "test"))
+    .Update();
+```
+
+**Example #6**. Constructing update expressions of the fly
+
+```csharp
+  bool condition = CheckCondition();
+  var query = session.Query.All()<Bar>
+    .Where(a => a.Id == 1)
+    .Set(a => a.Count, 2);
+
+  if(condition)
+    query = query.Set(a => a.Name, a => a.Name + "test");
+  query.Update();
+```
+
+**Example #7**. Updating lots of properties at once
+
+```csharp
+  session.Query.All<Bar>()
+    .Where(a => a.Id == 1)
+    Update(
+      a => new Bar(null) { Count = 2, Name = a.Name + "test", /*dozens of other properties...*/ });
+```
+
+**Example #8**. Deleting entities
+
+```csharp
+  session.Query.All<Foo>()
+    .Where(a => a.Id == 1)
+    .Delete();
+```

+There are 3 strategies that can be used for task execution:
+- **HandleReprocessibleException** strategy
     The strategy catches all reprocessible expections (deadlock and transaction serialization exceptions)
     and makes another attempt to execute the task
-- HandleUniqueConstraintViolation strategy
+- **HandleUniqueConstraintViolation** strategy
     The same as previous one but also catches unique constraint violation exception 
-- NoReprocess strategy
+- **NoReprocess** strategy
     No reprocessing is provided
 
 To indicate that a particular strategy should be used, use the following syntax:
