+##  Directory Structure
+
+The first and second levels are more of a directory
+
+Top level: seata-samples
+
+Second layer: at-sample, tcc-sample, saga-sample, xa-sample
+
+Third floor, The third layer is the specific sample and the naming convention is as follows:
+
+## naming
+
+naming with framework: spring-nacos-seata, springboot-naocs-zk-seata ...
+
+## dependency
+
+pom: The dependencies of each sample should be independent and should not depend on the dependencies of the parent pom of seata samples.
