-## Recommended Test Environment
-To avoid intermittent test failures (i.e., flaky tests), it is recommended to have a machine or virtual machine with the following specifications:
-
-* Minimum of 2CPUs.
-* Minimum of 2Gb of RAM.
-
-### How does the Dubbo Community collaborate?
-
-The Dubbo Community primarily communicates on GitHub through issues, discussions, and pull requests.
-
-- Issues: We use issues to track bugs and tasks. Any **work-related** item is associated with an issue.
-- Discussions: We use discussions for questions, early proposals, and announcements. Any **idea-related** item is associated with a discussion.
-- Pull Requests: We use pull requests to merge a set of changes from contributors into Dubbo.
-
-We have also implemented [a project board](https://github.com/orgs/apache/projects/337) to monitor all the items.
-
-Any essential changes should be discussed on the mailing list before they happen.
-
-### Seeking for help
-
-If you have questions such as:
-
-- What is Dubbo?
-- How do I use Dubbo?
-- Why did an unexpected result occur?
-
-Please start a discussion at https://github.com/apache/dubbo/discussions.
-
-However, if you encounter the following situations:
-
-- You're certain there's a bug that Dubbo needs to fix,
-- You believe a feature could be enhanced,
-- You have a detailed proposal for improving Dubbo,
-
-Please open an issue at https://github.com/apache/dubbo/issues.
-
-To ask effective questions, we recommend reading **[How To Ask Questions The Smart Way](https://github.com/selfteaching/How-To-Ask-Questions-The-Smart-Way/blob/master/How-To-Ask-Questions-The-Smart-Way.md)** first.

- * Condition Router directs traffics matching the 'when condition' to a particular address subset determined by the 'then condition'.
+ * ConditionRouter
- * One typical condition rule is like below, with
+ * It supports the conditional routing configured by "override://", in 2.6.x,
- * 1. the 'when condition' on the left side of '=>' contains matching rule like 'method=sayHello' and 'method=sayHi'
+ * refer to https://dubbo.apache.org/en/docs/v2.7/user/examples/routing-rule/ .
- * 2. the 'then condition' on the right side of '=>' contains matching rule like 'region=hangzhou' and 'address=*:20881'
+ * For 2.7.x and later, please refer to {@link org.apache.dubbo.rpc.cluster.router.condition.config.ServiceRouter}
- * <p>
+ * and {@link AppStateRouter}
- * By default, condition router support matching rules like 'foo=bar', 'foo=bar*', 'arguments[0]=bar', 'attachments[foo]=bar', 'attachments[foo]=1~100', etc.
+ * refer to https://dubbo.apache.org/zh/docs/v2.7/user/examples/routing-rule/ .
- * It's also very easy to add customized matching rules by extending {@link ConditionMatcherFactory}
- * and {@link ValuePattern}
