+## About the sample project naming explanation
+
+Rooch provides the command `rooch move new` to automatically create and initialize projects. When we want to write a new contract project, we can use this command to simplify our initialization work.
+
+We can use any legal character as the project name, including `-`, but when we use a project name with `-`, the `rooch move new` command will automatically use the project name as the address of this project.
+
+For example:
+
+```shell
+move rooch new hello-world
+```
+
+However, `-` is not a legal character for naming addresses (variables), so after we create the project using `rooch move new`, be sure to check the project address alias in the `Move.toml` file for illegal characters.
+
+Use `rooch move new` to create a project (name) with `-`. We recommend manually modifying the `Move.toml` file and replacing `-` with `_`.
+
+Another way is to directly use `_` as the hyphen for the project name word when creating the project.
+
+For example:
+
+```shell
+move rooch new hello_world
+```
+
+In Rooch's `examples`, the names of the projects we create use `_` connection. As for the actual development, which style to use, please decide according to your preferences.

+
+## 关于示例项目命名解释
+
+Rooch 提供自动创建并初始化项目的命令 `rooch move new`，当我们要编写新的合约项目时，可以利用这个命令简化我们的初始化工作。
+
+我们可以使用任何合法字符来作为项目名，包括 `-`，但是，当我们使用带有 `-` 的项目名时，`rooch move new` 命令会自动将项目名用作这个项目的地址。
+
+例如：
+
+```shell
+move rooch new hello-world
+```
+
+然而，`-` 不是命名地址（变量）的合法字符，所以当我们使用 `rooch move new` 创建好项目后，务必检查 `Move.toml` 文件中的项目地址别名是否存在非法字符。
+
+使用 `rooch move new` 创建带有 `-` 的项目（名），我们推荐手动修改 `Move.toml` 文件，将 `-` 替换为 `_`。
+
+另一种方式是，创建项目时，直接使用 `_` 作为项目名称单词的连接符号。
+
+例如：
+
+```shell
+move rooch new hello_world
+```
+
+在 Rooch 的 `examples` 中，我们创建的项目的名字统一使用 `_` 连接，至于实际开发中，使用那种风格，请根据您的喜好决定。
