-<!-- 
-  Thank you very much for contributing to Apache HugeGraph, we are happy that you want to help us improve it!
-
-  Here are some tips for you:
-    1. If this is your first time, please read the [contributing guidelines](https://github.com/apache/hugegraph/blob/master/CONTRIBUTING.md)
-
-    2. If a PR fix/close an issue, type the message "close xxx" (xxx is the link of related 
-issue) in the content, GitHub will auto link it (Required)
-
-    3. Name the PR title in "Google Commit Format", start with "feat | fix | perf | refactor | doc | chore", 
-      such like: "feat(core): support the PageRank algorithm" or "fix: wrong break in the compute loop" (module is optional)
-      skip it if you are unsure about which is the best component.
-
-    4. One PR address one issue, better not to mix up multiple issues.
-
-    5. Put an `x` in the `[ ]` to mark the item as CHECKED. `[x]` (or click it directly after 
-published)
--->
-
-## Purpose of the PR
-
-- close #xxx <!-- or use "fix #xxx", "xxx" is the ID-link of related issue, e.g: close #1024 -->
-
-<!--
-Please explain more context in this section, clarify why the changes are needed. 
-e.g:
-- If you propose a new API, clarify the use case for a new API.
-- If you fix a bug, you can clarify why it is a bug, and should be associated with an issue.
--->
-
-## Main Changes
-
-<!-- Please clarify what changes you are proposing. The purpose of this section is to outline the changes and how this PR fixes the issue. These change logs are helpful for better and faster reviews.)
-
-For example:
-
-- If you introduce a new feature, please show detailed design here or add the link of design documentation.
-- If you refactor some codes with changing classes, showing the class hierarchy will help reviewers.
-- If there is a discussion in the mailing list, please add the link. -->
-
-## Verifying these changes
-
-<!-- Please pick the proper options below -->
-
-- [ ] Trivial rework / code cleanup without any test coverage. (No Need)
-- [ ] Already covered by existing tests, such as *(please modify tests here)*.
-- [ ] Need tests and can be verified as follows:
-    - xxx
-
-## Does this PR potentially affect the following parts?
-
-<!-- DO NOT REMOVE THIS SECTION. CHECK THE PROPER BOX ONLY. -->
-
-- [ ]  Dependencies ([add/update license](https://hugegraph.apache.org/docs/contribution-guidelines/contribute/#321-check-licenses) info & [regenerate_dependencies](../hugegraph-server/hugegraph-dist/scripts/dependency/regenerate_known_dependencies.sh)) <!-- Don't forget to add/update the info in "LICENSE" & "NOTICE" files (both in root & dist module) -->
-- [ ]  Modify configurations
-- [ ]  The public API
-- [ ]  Other affects (typed here)
-- [ ]  Nope
-
-
-## Documentation Status
-
-<!-- DO NOT REMOVE THIS SECTION. CHECK THE PROPER BOX ONLY. -->
-
-- [ ]  `Doc - TODO` <!-- Your PR changes impact docs and you will update later -->
-- [ ]  `Doc - Done` <!-- Related docs have been already added or updated -->
-- [ ]  `Doc - No Need` <!-- Your PR changes don't impact/need docs -->

-# [New Podling Proposal of HugeGraph](https://cwiki.apache.org/confluence/display/INCUBATOR/New+Podling+Proposal)
-
-## Abstract
-
-HugeGraph is a high-performance scalable graph database.
-
-## Proposal
-
-HugeGraph is a large-scale and easy-to-use graph database. In the cases of 100+ billion data (vertices and edges), HugeGraph has complete HTAP capabilities built into its internal system. The design goal of HugeGraph is to achieve a balance between availability, performance, and cost.
-
-We believe that the HugeGraph project will benefit the open-source community if HugeGraph is introduced into the Apache Software Foundation.
-
-### Background
-
-HugeGraph graph database was initially developed at Baidu, the leading search engine company in China. HugeGraph was designed to solve the large-scale graph analysis requirements for the task of anti-fraud. Relational databases are usually at a disadvantage in dealing with relational analysis, due to slow join performance, especially in the case of a large-scale graph with multiple dimensions and deep association relationships. Graph databases are in general considered a good alternative in dealing with large-scale relational analysis.
-
-### Rationale
-
-Generally, most graph databases can only process up to 1-billion-scale graphs, but it lacks a system to process 100-billion-scale graphs. Some graph databases may only support online query (OLTP), and some graph platforms only support graph computing (OLAP). HugeGraph is designed to support both online query and graph computing in the scenarios of 100+ billion data.
-
-### Initial Goals
-
-Although most of the main development of HugeGraph has been completed, there are several areas that still need future development. Some areas we want to focus on in the Apache incubation stage include:
-
-- Higher graph computing loading performance: the current architecture (especially the separation of computing and storage) brings greater flexibility and cost savings, but with some performance overhead, which needs to be improved.
-- RocksDB-based sharding storage development, based on the affinity architecture of query and storage. Since RocksDB is known for its good performance, but currently HugeGraph only supports the raft-based replication mode, we plan to support scale-out and distributed atomic transactions for RocksDB-based storage.
-- Parallel OLTP query: at present, HugeGraph can perform parallel OLAP graph-computing, but the OLTP query only supports parallel execution on a single machine. In certain scenarios, the OLTP query needs to be implemented in parallel on multiple machines.
-- Higher-performance queries: such as supporting faster query optimization, parallel primitive collections, and fine-grained caching strategies.
-- Better usability: more OLTP/OLAP algorithms, APIs and toolchains, rich UI, etc...
-- More language clients: such as supporting Python and Go languages.
-- Some other optimizations: such as supporting pre-sorting graph loading.
-
-### Current Status
-
-#### Meritocracy
-
-HugeGraph was incubated at Baidu in 2016 and open-sourced on [GitHub](https://github.com/hugegraph/hugegraph) in 2018. The project (including sub-projects) now has 30+ contributors from many companies. Some of these contributors become committers, and the project has hundreds of known users around the world. We will follow Apache's Meritocracy way to re-organize the community roles. We have set up the PPMC Team and Committer Team. Of course, contributions are welcomed and highly valued. New contributors are guided and reviewed by existing PMC members. When an active contributor has submitted enough good patches, PMC will start a vote to promote him/her to become a member of the Committer Team or PMC Team.
-
-#### Community
-
-Baidu has been building a community around HugeGraph users and developers for the last 3 years, and now we make use of GitHub as code hosting and community communication. The most of core developers are from Baidu. Besides, there are 10+ contributors from other companies such as NetEase, 360, Iflytek, and Huya. We hope to grow the base of contributors by inviting all those who offer contributions through The Apache Way. 
-
-#### Core Developers
-
-The core developers are all experienced open-source developers. They have operated the HugeGraph Community for 3 years, and they are contributors to Linux kernel, OpenStack, Ceph, RocksDB, Apache TinkerPop, Apache Hadoop, and Apache Groovy.
-
-#### Alignment
-
-HugeGraph implements the API of [Apache TinkerPop](https://tinkerpop.apache.org/), which defines the [Gremlin](https://tinkerpop.apache.org/gremlin.html). Gremlin is a powerful graph traversal language, and various complicated graph queries can be accomplished through Gremlin. The TinkerPop ecosystem based on Java is relatively mature in terms of graph databases. We use Java language, which is developed efficient and stable, to develop upper-level components like graph engine, graph computing, graph API, and graph tools; and we manage storage through JNI which is able to freely manage memory and execute efficiently.
-
-### Known Risks
-
-#### Project Name
-
-We have checked and believe the name is [suitable](https://github.com/hugegraph/hugegraph/issues/1646) and the project has legal permission to continue using its current name. There are no other projects found using this name through Google Search.
-
-#### Relationship with Titan/Janus Graph
-
-In the early stage of the project, we referred to the storage structure of Titan/Janus Graph, some folks thought that HugeGraph was forked from Titan/Janus. In fact, HugeGraph is not based on these projects. HugeGraph is developed completely from scratch and in the process it addressed many new challenges. Certainly, the project was inspired by Titan/Janus and we are really grateful for these inspirations.
-
-### Orphaned products
-
-Due to a small and limited number of committers, the project has a relatively small risk of becoming an orphan project. However, the committers have been operating the HugeGraph Community for 3 years in the spirit of open-source, and continue to develop new contributors to participate.
-
-#### Inexperience with Open-Source
-
-HugeGraph has been open-sourced on GitHub for 3 years, during which committers submitted code and documents in full compliance with open-source specifications and requirements.
-
-#### Length of Incubation
-
-Expect to enter incubation in 4 months and graduate in about 2 years.
-
-#### Homogenous Developers
-
-The developers on the current list come from several different companies plus many independent volunteers, but the most of committers are from Baidu. The developers are geographically concentrated in China now. They are experienced with working in a distributed environment in other open-source projects, e.g. OpenStack.
-
-#### Reliance on Salaried Developers
-
-Most of the developers are paid by their employer to contribute to this project. Given some volunteer developers and the committers' sense of ownership for the code, the project could continue even if no salaried developers contributed to the project.
-
-#### Relationships with Other Apache Products
-
-HugeGraph follows the Apache TinkerPop specification, uses Apache Commons, Apache HttpClient, and Apache HttpCore to implement the basic functions. Users can choose Apache Cassandra or Apache HBase as one of the storage backends of HugeGraph.
-
-#### An Excessive Fascination with the Apache Brand
-
-Although we expect that the Apache brand may help attract more contributors, our interest in starting this project is based on the factors mentioned in the fundamentals section. We are interested in joining ASF to increase our connections in the open-source world. Based on extensive collaboration, it is possible to build a community of developers and committers that live longer than the founder.
-
-### Documentation
-
-HugeGraph documentation is provided on https://hugegraph.github.io/hugegraph-doc/ in Simplified Chinese, the complete English version of the documentation is being prepared.
-
-### Initial Source
-
-This project consists of 2 core sub-projects and 2 other sub-projects, all of which are hosted by [GitHub hugegraph organization](https://github.com/orgs/hugegraph/repositories) since 2018. The codes are already under Apache License Version 2.0. The git address of sub-project repositories are as follows:
-
-1. The graph database repository `hugegraph`, core sub-project, including graph server, graph engine, and graph storage: https://github.com/hugegraph/hugegraph
-2. The graph computing repository `hugegraph-computer`, core sub-project, including graph computing and graph algorithms: https://github.com/hugegraph/hugegraph-computer
-3. The common functions repository `hugegraph-commons`: https://github.com/hugegraph/hugegraph-commons

-
-### Source and Intellectual Property Submission Plan
-
-The code is currently under Apache License Version 2.0, and it was verified there were no intellectual property or license issues when it was open-sourced by Baidu in 2018. Baidu will provide SGA and all committers will sign ICLA after HugeGraph is accepted into the Incubator.
-
-#### External Dependencies
-
-As all dependencies are managed by Apache Maven, none of the external libraries need to be packaged in a source distribution. All dependencies have Apache compatible licenses except for 4 dependencies: MySQL Connector (GPL), word (GPL), JBoss Logging 3 (LGPL), and jnr-posix (LGPL+GPL), we will remove these dependencies in the future.

-##### 3.2.1 Check licenses
-If we want to add new third-party dependencies to the `HugeGraph` project, we need to do the following things:
-1. Find the third-party dependent repository, put the dependent `license` file into [./hugegraph-dist/release-docs/licenses/](https://github.com/apache/incubator-hugegraph/tree/master/hugegraph-dist/release-docs/licenses) path.
-2. Declare the dependency in [./hugegraph-server/hugegraph-dist/release-docs/LICENSE](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-dist/release-docs/LICENSE) `LICENSE` information.
-3. Find the NOTICE file in the repository and append it to [./hugegraph-server/hugegraph-dist/release-docs/NOTICE](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-dist/release-docs/NOTICE) file (skip this step if there is no NOTICE file).
-4. Execute locally [./hugegraph-server/hugegraph-dist/scripts/dependency/regenerate_known_dependencies.sh](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-dist/scripts/dependency/regenerate_known_dependencies.sh) to update the dependency list [known-dependencies.txt](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-dist/scripts/dependency/known-dependencies.txt) (or manually update).
-
-**Example**: A new third-party dependency is introduced into the project -> `ant-1.9.1.jar`
-- The project source code is located at: https://github.com/apache/ant/tree/rel/1.9.1
-- LICENSE file: https://github.com/apache/ant/blob/rel/1.9.1/LICENSE
-- NOTICE file: https://github.com/apache/ant/blob/rel/1.9.1/NOTICE

-Apache HugeGraph (incubating) is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.
-
-Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, 
-and decision making process have stabilized in a manner consistent with other successful ASF projects.
-
-While incubation status is not necessarily a reflection of the completeness or stability of the code, 
-it does indicate that the project has yet to be fully endorsed by the ASF.

-## What is Apache HugeGraph?
-
-[HugeGraph](https://hugegraph.apache.org/) is a fast-speed and highly-scalable [graph database](https://en.wikipedia.org/wiki/Graph_database). 
-Billions of vertices and edges can be easily stored into and queried from HugeGraph due to its excellent OLTP ability. 
-As compliance to [Apache TinkerPop 3](https://tinkerpop.apache.org/) framework, various complicated graph queries can be 
-achieved through [Gremlin](https://tinkerpop.apache.org/gremlin.html)(a powerful graph traversal language).

+## Learn More
 
-## Quick Start
-
-### 1. Docker Way (Convenient for Test)
-
-We can use `docker run -itd --name=graph -p 8080:8080 hugegraph/hugegraph` to quickly start an inner 
-HugeGraph server with `RocksDB` (in backgrounds) for **test/dev**.
-You can visit [doc page](https://hugegraph.apache.org/docs/quickstart/hugegraph-server/#3-deploy) or
-the [README](hugegraph-server/hugegraph-dist/docker/README.md) for more details. ([Docker Compose](./hugegraph-server/hugegraph-dist/docker/example))
-
-> Note:
->  
-> 1. The docker image of hugegraph is a convenience release, but not **official distribution** artifacts. You can find more details from [ASF Release Distribution Policy](https://infra.apache.org/release-distribution.html#dockerhub).
-> 
-> 2. Recommend to use `release tag`(like `1.2.0`) for the stable version. Use `latest` tag to experience the newest functions in development.
-
-### 2. Download Way
-
-Visit [Download Page](https://hugegraph.apache.org/docs/download/download/) and refer the [doc](https://hugegraph.apache.org/docs/quickstart/hugegraph-server/#32-download-the-binary-tar-tarball) 
-to download the latest release package and start the server.
-
-### 3. Source Building Way
-
-Visit [Source Building Page](https://hugegraph.apache.org/docs/quickstart/hugegraph-server/#33-source-code-compilation) and follow the 
-steps to build the source code and start the server.
-
-The project [doc page](https://hugegraph.apache.org/docs/) contains more information on HugeGraph
-and provides detailed documentation for users. (Structure / Usage / API / Configs...)
-
-And here are links of other **HugeGraph** component/repositories:
