 To be clear, the "host" actually means the container which is running the act runner now, instead of the host machine.
 
+### Configuring cache when starting a Runner using docker image
+
+If you do not intend to use `actions/cache` in workflow, you can ignore this section.
+
+If you use `actions/cache` without any additional configuration, it will return the following error:
+> Failed to restore: getCacheEntry failed: connect ETIMEDOUT <ip>:<port>
+
+The error occurs because the runner container and job container are on different networks, so the job container cannot access the runner container.
+
+Therefore, it is essential to configure the cache action to ensure its proper functioning. Follow these steps:
+
+- 1.Obtain the LAN IP address of the host machine where the runner container is running.
+- 2.Find an available port number on the host machine where the runner container is running.
+- 3.Configure the following settings in the configuration file:
+
+```yaml
+cache:
+  enabled: true
+  dir: ""
+  # Use the LAN IP obtained in step 1
+  host: "192.168.8.17"
+  # Use the port number obtained in step 2
+  port: 8088
+```
+
+- 4.When starting the container, map the cache port to the host machine:
+
+```bash
+docker run \
+  --name gitea-docker-runner \
+  -p 8088:8088 \
+  -d gitea/act_runner:nightly
+```

 ### Labels
 
 The labels of a runner are used to determine which jobs the runner can run, and how to run them.

+### 当您使用 Docker 镜像启动 Runner，如何配置 Cache
+
+如果你不打算在工作流中使用 `actions/cache`，你可以忽略本段。
+
+如果您在使用 `actions/cache` 时没有进行额外的配置，将会返回以下错误信息：
+> Failed to restore: getCacheEntry failed: connect ETIMEDOUT <ip>:<port>
+
+这个错误的原因是 runner 容器和作业容器位于不同的网络中，因此作业容器无法访问 runner 容器。
+因此，配置 cache 动作以确保其正常运行是非常重要的。请按照以下步骤操作：
+
+- 1.获取 Runner 容器所在主机的 LAN（本地局域网） IP 地址。
+- 2.获取一个 Runner 容器所在主机的空闲端口号。
+- 3.在配置文件中如下配置：
+
+```yaml
+cache:
+enabled: true
+dir: ""
+# 使用步骤 1. 获取的 LAN IP
+host: "192.168.8.17" 
+# 使用步骤 2. 获取的端口号
+port: 8088         
+```
+
+- 4.启动容器时, 将 Cache 端口映射至主机。
+
+```bash
+docker run \
+  --name gitea-docker-runner \
+  -p 8088:8088 \ 
+  -d gitea/act_runner:nightly
+```
