-# How To Contribute
+Please refer to the contribution document [How to contribute](docs/docs/en/contribute/join/contribute.md)
 
-Start by forking the dolphinscheduler GitHub repository, make changes in a branch and then send a pull request.
+## How to Build
 
-## Set up your dolphinscheduler GitHub Repository
+```bash
-
+./mvnw clean install -Prelease
-There are three branches in the remote repository currently:
-
-  - `master` : normal delivery branch. After the stable version is released, the code for the stable version branch is merged into the master branch.
-            
-  - `dev` : daily development branch. The daily development branch, the newly submitted code can pull requests to this branch.
-  
-  - `x.x.x-release` : the stable release version.
-
-So, you should fork the `dev` branch.
-
-After forking the [dolphinscheduler upstream source repository](https://github.com/apache/dolphinscheduler/fork) to your personal repository, you can set your  personal development environment.
-
-```sh
-cd <your work direcotry>
-git clone <your personal forked dolphinscheduler repo>
-cd dolphinscheduler
 ```
 
-## Set git remote as `upstream`
+### Build with different Zookeeper versions
 
-Add remote repository address, named upstream
+The default Zookeeper Server version supported is 3.8.0.
-
+```bash
-```sh
+# Default Zookeeper 3.8.0
-git remote add upstream https://github.com/apache/dolphinscheduler.git
+./mvnw clean install -Prelease
+# Support to Zookeeper 3.4.6+
+./mvnw clean install -Prelease -Dzk-3.4
 ```

-There will be two repositories at this time: origin (your own warehouse) and upstream (remote repository)
+dolphinscheduler-dist/target/apache-dolphinscheduler-${latest.release.version}-src.tar.gz: Source code package of DolphinScheduler
-
-Get/update remote repository code (already the latest code, skip it).
-
-
-```sh
-git fetch upstream
 ```
-
-Synchronize remote repository code to local repository
-
-```sh
-git checkout origin/dev
-git merge --no-ff upstream/dev
-```
-
-If remote branch has a new branch `dev-1.0`, you need to synchronize this branch to the local repository, then push to your own repository.
-
-```sh
-git checkout -b dev-1.0 upstream/dev-1.0
-git push --set-upstream origin dev-1.0
-```
-
-## Create your feature branch
-
-Before making code changes, make sure you create a separate branch for them.
-
-```sh
-git checkout -b <your-feature-branch> dev
-```
-
-## Commit changes
-
-After modifying the code locally, submit it to your own repository:
-
-```sh
-git commit -m 'information about your feature'
-```
-
-## Push to the branch
-
-Push your locally committed changes to the remote origin (your fork).
-
-```sh
-git push origin <your-feature-branch>
-```
-
-## Create a pull request
-
-After submitting changes to your remote repository, you should click on the new pull request On the following github page.
-
-<p align = "center">

- Stability | Accessibility | Features | Scalability |
+## QuickStart
- --------- | ------------- | -------- | ------------|
+
-Decentralized multi-master and multi-worker | Visualization of workflow key information, such as task status, task type, retry times, task operation machine information, visual variables, and so on at a glance.  |  Support pause, recover operation | Support customized task types
+- For quick experience
-support HA | Visualization of all workflow operations, dragging tasks to draw DAGs, configuring data sources and resources. At the same time, for third-party systems, provide API mode operations. | Users on DolphinScheduler can achieve many-to-one or one-to-one mapping relationship through tenants and Hadoop users, which is very important for scheduling large data jobs.  | The scheduler supports distributed scheduling, and the overall scheduling capability will increase linearly with the scale of the cluster. Master and Worker support dynamic adjustment.
+  - Want to [start with standalone](https://dolphinscheduler.apache.org/en-us/docs/3.1.5/guide/installation/standalone)
-Overload processing: By using the task queue mechanism, the number of schedulable tasks on a single machine can be flexibly configured. Machine jam can be avoided with high tolerance to numbers of tasks cached in task queue. | One-click deployment | Support traditional shell tasks, and big data platform task scheduling: MR, Spark, SQL (MySQL, PostgreSQL, hive, spark SQL), Python, Procedure, Sub_Process |  |
+  - Want to [start with Docker](https://dolphinscheduler.apache.org/en-us/docs/3.1.5/guide/start/docker)

 Apache DolphinScheduler aims to solve complex big data task dependencies and to trigger relationships in data OPS orchestration for various big data applications. Solves the intricate dependencies of data R&D ETL and the inability to monitor the health status of tasks. DolphinScheduler assembles tasks in the Directed Acyclic Graph (DAG) streaming mode, which can monitor the execution status of tasks in time, and supports operations like retry, recovery failure from specified nodes, pause, resume, and kill tasks, etc.

 In the early schedule design, if there is no priority design and use the fair scheduling, the task submitted first may complete at the same time with the task submitted later, thus invalid the priority of process or task. So we have re-designed this, and the following is our current design:

 # API design standard

 A standardized and unified API is the cornerstone of project design.The API of DolphinScheduler follows the REST ful standard. REST ful is currently the most popular Internet software architecture. It has a clear structure, conforms to standards, is easy to understand and extend.
 
 This article uses the DolphinScheduler API as an example to explain how to construct a Restful API.
 
 ## 1. URI design
+
 REST is "Representational State Transfer".The design of Restful URI is based on resources.The resource corresponds to an entity on the network, for example: a piece of text, a picture, and a service. And each resource corresponds to a URI.
 
 + One Kind of Resource: expressed in the plural, such as `task-instances`、`groups` ;

 + A Sub Resource：`/instances/{instanceId}/tasks/{taskId}`;
 
 ## 2. Method design
+
 We need to locate a certain resource by URI, and then use Method or declare actions in the path suffix to reflect the operation of the resource.
 
 ### ① Query - GET
+
 Use URI to locate the resource, and use GET to indicate query.
 
 + When the URI is a type of resource, it means to query a type of resource. For example, the following example indicates paging query `alter-groups`.
+
 ```
 Method: GET
 /dolphinscheduler/alert-groups
 ```
 
 + When the URI is a single resource, it means to query this resource. For example, the following example means to query the specified `alter-group`.
+
 ```
 Method: GET
 /dolphinscheduler/alter-groups/{id}
 ```
 
 + In addition, we can also express query sub-resources based on URI, as follows:
+
 ```
 Method: GET
 /dolphinscheduler/projects/{projectId}/tasks
 ```
 
 **The above examples all represent paging query. If we need to query all data, we need to add `/list` after the URI to distinguish. Do not mix the same API for both paged query and query.**
+
 ```
 Method: GET
 /dolphinscheduler/alert-groups/list

 ## 3. Parameter design
+
 There are two types of parameters, one is request parameter and the other is path parameter. And the parameter must use small hump.
 
 In the case of paging, if the parameter entered by the user is less than 1, the front end needs to automatically turn to 1, indicating that the first page is requested; When the backend finds that the parameter entered by the user is greater than the total number of pages, it should directly return to the last page.
 
 ## 4. Others design

 ### base URL
+
 The URI of the project needs to use `/<project_name>` as the base path, so as to identify that these APIs are under this project.

 - In the decentralized design, there is usually no Master/Slave concept, all roles are the same, the status is equal, the global Internet is a typical decentralized distributed system, networked arbitrary node equipment down machine , all will only affect a small range of features.
 - The core design of decentralized design is that there is no "manager" that is different from other nodes in the entire distributed system, so there is no single point of failure problem. However, since there is no "manager" node, each node needs to communicate with other nodes to get the necessary machine information, and the unreliable line of distributed system communication greatly increases the difficulty of implementing the above functions.
 - In fact, truly decentralized distributed systems are rare. Instead, dynamic centralized distributed systems are constantly emerging. Under this architecture, the managers in the cluster are dynamically selected, rather than preset, and when the cluster fails, the nodes of the cluster will spontaneously hold "meetings" to elect new "managers". Go to preside over the work. The most typical case is the Etcd implemented in ZooKeeper and Go.
-
 - Decentralization of DolphinScheduler is the registration of Master/Worker to ZooKeeper. The Master Cluster and the Worker Cluster are not centered, and the Zookeeper distributed lock is used to elect one Master or Worker as the “manager” to perform the task.

 In the early scheduling design, if there is no priority design and fair scheduling design, it will encounter the situation that the task submitted first may be completed simultaneously with the task submitted subsequently, but the priority of the process or task cannot be set.

 - According to **different process instance priority** prioritizes **same process instance priority** prioritizes **task priority within the same process** takes precedence over **same process** commit order from high Go to low for task processing.
-
   - The specific implementation is to resolve the priority according to the json of the task instance, and then save the **process instance priority _ process instance id_task priority _ task id** information in the ZooKeeper task queue, when obtained from the task queue, Through string comparison, you can get the task that needs to be executed first.
-
     - The priority of the process definition is that some processes need to be processed before other processes. This can be configured at the start of the process or at the time of scheduled start. There are 5 levels, followed by HIGHEST, HIGH, MEDIUM, LOW, and LOWEST. As shown below

 Pull Request is a way of software cooperation, which is a process of bringing code involving different functions into the trunk. During this process, the code can be discussed, reviewed, and modified.
 
 In Pull Request, we try not to discuss the implementation of the code. The general implementation of the code and its logic should be determined in Issue. In the Pull Request, we only focus on the code format and code specification, so as to avoid wasting time caused by different opinions on implementation.

 ## Timeliness Check of Single Table Check
+
 ### Inspection Introduction
+
 The timeliness check is used to check whether the data is processed within the expected time. The start time and end time can be specified to define the time range. If the amount of data within the time range does not reach the set threshold, the check task will be judged as fail.

 ## Accuracy Check of Multi-table
+
 ### Inspection Introduction
+
 Accuracy checks are performed by comparing the accuracy differences of data records for selected fields between two tables, examples are as follows
 - table test1
 
 | c1 | c2 |
-| :---: | :---: |
+|:--:|:--:|
-| a | 1 |
+| a  | 1  |
-| b | 2 |
+| b  | 2  |
 
 - table test2
 
 | c21 | c22 |
-| :---: | :---: |
+|:---:|:---:|
-| a | 1 |
+|  a  |  1  |
-| b | 3 |
+|  b  |  3  |
 
 If you compare the data in c1 and c21, the tables test1 and test2 are exactly the same. If you compare c2 and c22, the data in table test1 and table test2 are inconsistent.

 ## Comparison of the values checked by the two tables
+
 ### Inspection Introduction
+
 Two-table value comparison allows users to customize different SQL statistics for two tables and compare the corresponding values. For example, for the source table A, the total amount of a certain column is calculated, and for the target table, the total amount of a certain column is calculated. value sum2, compare sum1 and sum2 to determine the check result.
