 If using Docker, the `act_runner` user should also be added to the `docker` group before starting the service. Keep in mind that this effectively gives `act_runner` root access to the system [[1]](https://docs.docker.com/engine/security/#docker-daemon-attack-surface).

-## Configuration variable
-
-You can create configuration variables on the user, organization and repository level.
-The level of the variable depends on where you created it.
-
-### Naming conventions
-
-The following rules apply to variable names:
-
-- Variable names can only contain alphanumeric characters (`[a-z]`, `[A-Z]`, `[0-9]`) or underscores (`_`). Spaces are not allowed.
-
-- Variable names must not start with the `GITHUB_` and `GITEA_` prefix.
-
-- Variable names must not start with a number.
-
-- Variable names are case-insensitive.
-
-- Variable names must be unique at the level they are created at.
-
-- Variable names must not be `CI`.
-
-### Using variable
-
-After creating configuration variables, they will be automatically filled in the `vars` context.
-They can be accessed through expressions like `{{ vars.VARIABLE_NAME }}` in the workflow.
-
-### Precedence
-
-If a variable with the same name exists at multiple levels, the variable at the lowest level takes precedence:
-A repository variable will always be chosen over an organization/user variable.

-## 变量
-
-您可以创建用户、组织和仓库级别的变量。变量的级别取决于创建它的位置。
-
-### 命名规则
-
-以下规则适用于变量名：
-
-- 变量名称只能包含字母数字字符 (`[a-z]`, `[A-Z]`, `[0-9]`) 或下划线 (`_`)。不允许使用空格。
-
-- 变量名称不能以 `GITHUB_` 和 `GITEA_` 前缀开头。
-
-- 变量名称不能以数字开头。
-
-- 变量名称不区分大小写。
-
-- 变量名称在创建它们的级别上必须是唯一的。
-
-- 变量名称不能为 “CI”。
-
-### 使用
-
-创建配置变量后，它们将自动填充到 `vars` 上下文中。您可以在工作流中使用类似 `{{ vars.VARIABLE_NAME }}` 这样的表达式来使用它们。
-
-### 优先级
-
-如果同名变量存在于多个级别，则级别最低的变量优先。
-仓库级别的变量总是比组织或者用户级别的变量优先被选中。
