 With the popularity of microservices architecture, more and more people are trying to use microservices to architect their systems. In this we encounter problems such as distributed transactions. To solve these problems, I did not find simplicity and Easy to use solution, so I decided to create such a library to solve this problem.

 Now in addition to solving distributed transaction problems, CAP's other important function is to use it as an EventBus. It has all of the features of EventBus and provides a more simplified way to handle publish/subscribe in EventBus.
 
-### Persistence
+## Persistence
 
 The CAP relies on the local database for persistence of messages. The CAP uses this method to deal with situations in which all messages are lost due to environmental or network anomalies. The reliability of messages is the cornerstone of distributed transactions, so messages cannot be lost under any circumstances.

+# IMPLEMENTATION
 Users can get a ICapPublisher interface from the ASP.NET Core DI container to publish a message .It is initialized by  configurations in the `ConfigureServices` and `configure` method in the Startup.cs file,just like the way to initialize a `MiddleWare` in ASP.NET Core.
 
-### Message Table
+## Message Table
 
 After initialized, CAP will create two tables in the client side,they are `Cap.Published` and `Cap.Received`. Please noted that different databases may deal letter case differently,if you do not explicitly specify the Schema or the TableName Prefix before project startup,the default names are the ones mentioned above.
