+# BigchainDB 服务器
+
+BigchainDB 是区块链数据库. 这是 _BigchainDB 服务器_ 的仓库.
+
+## 基础知识
+
+* [尝试快速开始](https://docs.bigchaindb.com/projects/server/en/latest/quickstart.html)
+* [阅读 BigchainDB 2.0 白皮书](https://www.bigchaindb.com/whitepaper/)
+* [查阅漫游指南](https://www.bigchaindb.com/developers/guide/)
+
+## 运行和测试 `master` 分支的 BigchainDB 服务器
+
+运行和测试最新版本的 BigchainDB 服务器非常简单. 确认你有安装最新版本的 [Docker Compose](https://docs.docker.com/compose/install/). 当你准备好了, 打开一个终端并运行:
+
+```text
+git clone https://github.com/bigchaindb/bigchaindb.git
+cd bigchaindb
+make run
+```
+
+BigchainDB 应该可以通过 `http://localhost:9984/` 访问.
+
+这里也有一些其他的命令你可以运行:
+
+* `make start`: 通过源码和守护进程的方式运行 BigchainDB (通过 `make stop` 停止).
+* `make stop`: 停止运行 BigchainDB.
+* `make logs`: 附在日志上.
+* `make test`: 运行所有单元和验收测试.
+* `make test-unit-watch`: 运行所有测试并等待. 每次更改代码时都会再次运行测试.
+* `make cov`: 检查代码覆盖率并在浏览器中打开结果.
+* `make doc`: 生成 HTML 文档并在浏览器中打开它.
+* `make clean`: 删除所有构建, 测试, 覆盖和 Python 生成物.
+* `make reset`: 停止并移除所有容器. 警告: 您将丢失存储在 BigchainDB 中的所有数据.
+
+查看所有可用命令, 请运行 `make`.

    - In `setup.py`, _maybe_ update the development status item in the `classifiers` list. For example, one allowed value is `"Development Status :: 5 - Production/Stable"`. The [allowed values are listed at pypi.python.org](https://pypi.python.org/pypi?%3Aaction=list_classifiers).
