+    **JustEnoughVCS Upstream Vault Commands**
+    This program directly creates, manages, and runs JustEnoughVCS upstream vaults.
+    **Tip**: It directly operates on vault data - please operate with caution!
+    * With great power comes great responsibility *
+
+    **Create Vault**:
+      jvv create <VAULT_NAME> - Create a vault in the given directory name
+      jvv init - Create a vault in the current directory
+
+    **Query**:
+      jvv here - Query information about the current directory
+      jvv member list - Query all members
+
+    **Member Management**:
+      jvv member <register/remove> <MEMBER_NAME> - Register or remove members
+
+    **Service**:
+      jvv service listen - Run the server in the current vault
+
+    Additionally, you can use jvv <CMD_NAME> --help to query more detailed help!
+
+  here: |
+    **Query Vault Information Here**
+    Displays different information based on the current directory:
+      - Root *(./)*: Basic vault information
+      - Members *(./members/)*: Members and key registrations
+      - Storage *(./storage/)*: File count and total size
+      - Sheets *(./sheets/)*: Tables and their managers
+
+    **Example**: cd ./target_dir/ && jvv here
+
+  create: |
+    **Create a new vault with the given name**
+    **Usage**: jvv create <VAULT_NAME>
+
+    **Example**: jvv create MyVault
+    Creates a directory named 'MyVault' and initializes a vault inside it.
+
+  init: |
+    **Initialize a vault in the current directory**
+    **Usage**: jvv init
+
+    Uses the current directory's name as the vault name.
+
+  member: |
+    **Member Management**
+    **Usage**: jvv member <register/remove> <MEMBER_NAME>
+
+    Register or remove members based on the given member name.
+
+    It is recommended to use the "snake_case" naming format,
+    as it will be stored in this format in the configuration file
+    **Example**: jvv member register vault_member
+
+    **Query**: jvv member list
+    Equivalent to running `jvv here` in the members directory.
+
+    **Tip**: Does not manage private keys automatically. Keys must be handled manually.
+
+  service: |
+    **Service Management**
+    **Usage**:
+    jvv service listen - Start the vault server in the current vault to accept client connections
+      You can use --no-log to disable log output
+
+  fail:
+    jvcs: "JustEnoughVCS Error: %{err}"
+
+    no_vault_here: No vault found here
+
+    tokio:
+      fs:

+

+        **Tip**: You can use jvv here --help to learn how to view vault details
+
+    create: Successfully created vault at `%{name}`!
+
+    init: Successfully initialized vault here!
+

+    **JustEnoughVCS 上游库命令**
+    该程序直接创建、管理、运行 JustEnoughVCS 的上游库
+    **注意**：它能直接操作库的数据，请谨慎使用！*（能力越大，责任越大）*
+
+    **创建库**：
+      jvv create <名称> - 在给定的目录名称中创建库
+      jvv init - 在当前目录中创建库
+
+    **查询**：
+      jvv here - 查询当前目录的信息
+      jvv member list - 查询所有成员
+
+    **成员管理**：
+      jvv member <register/remove> <成员名称> - 注册或删除成员
+
+    **服务**：
+      jvv service listen - 在当前库中运行服务端
+
+    另外，你可以使用 jvv <命令名称> --help 来查询更详细的帮助！
+
+  here: |
+    **查询此处库的信息**
+    在不同目录执行该命令时会查询不同的信息：
+      1. 当根目录 *(./)* 时：查询库的基本信息
+      2. 当成员目录 *(./members/)* 时：查询库的成员和密钥注册信息
+      3. 当存储目录 *(./storage/)* 时：查询库托管的文件总数量、总大小
+      4. 当表目录 *(./sheets/)* 时：查询库中所有的表和其管理者
+
+    **例如**：cd ./你需要查询的目录/ && jvv here
+
+  create: |
+    **在给定的目录名称中创建库**
+    **使用方法**：jvv create **<库名称>**
+
+    **例如**：jvv create MyVault
+    上述操作会在当前目录创建目录 MyVault，然后在该目录内初始化库
+
+  init: |
+    **在当前目录创建库**
+    **使用方法**：jvv init
+
+    该命令会在当前所在的目录创建库，库名称由当前所在目录名称决定
+
+  member: |
+    **成员管理**
+    **使用方法**：jvv member <register/remove> <成员名称>
+
+    根据给定的 成员名称，注册（若不存在）或移除（若存在）指定成员
+
+    推荐使用 "snake_case" 命名格式，因为在配置文件中将以该格式存储
+    **例如**：jvv member register vault_member
+
+    **查询**：jvv member list
+    该命令的效果和在库的成员目录中执行 jvv here 命令等效
+
+    **注意**：该命令不会影响到库中私钥目录，请手动添加或删除私钥！
+
+  service: |
+    **服务设置相关**
+    **使用方法**：
+    jvv service listen - 在当前库中启动服务器，以接受客户端连接
+      你可以使用 --no-log 来禁用日志输出
+
+  fail:
+    jvcs: JustEnoughVCS 错误：%{err}
+
+    no_vault_here: 此处并没有找到库文件
+
+    tokio:
+      fs:
