+# Gitea Actions Runner 配置指南
+
+## 概述
+
+Gitea Actions 是 Gitea 的 CI/CD 系统，与 GitHub Actions 兼容。
+
+## 配置步骤
+
+### 1. 启用 Gitea Actions
+
+编辑 Gitea 配置文件 (`/etc/gitea/app.ini` 或 `~/.gitea/conf/app.ini`):
+
+```ini
+[actions]
+ENABLED = true
+DEFAULT_ACTIONS_URL = github
+```
+
+重启 Gitea:
+```bash
+sudo systemctl restart gitea
+```
+
+### 2. 安装 Runner
+
+#### macOS 安装
+
+```bash
+# 下载 Runner
+mkdir -p ~/gitea-runner
+cd ~/gitea-runner
+curl -L https://github.com/actions/runner/releases/latest/download/actions-runner-darwin-x64-2.311.0.tar.gz -o runner.tar.gz
+tar xzf runner.tar.gz
+
+# 配置 Runner
+./config.sh --url http://192.168.120.110:4000/damai/readflow \
+            --token <TOKEN_FROM_GITEA> \
+            --name macos-runner \
+            --runnergroup default
+
+# 启动 Runner
+./run.sh
+```
+
+#### Linux 安装
+
+```bash
+# 下载 Runner
+mkdir -p ~/gitea-runner
+cd ~/gitea-runner
+curl -L https://github.com/actions/runner/releases/latest/download/actions-runner-linux-x64-2.311.0.tar.gz -o runner.tar.gz
+tar xzf runner.tar.gz
+
+# 配置 Runner
+./config.sh --url http://192.168.120.110:4000/damai/readflow \
+            --token <TOKEN_FROM_GITEA> \
+            --name linux-runner \
+            --runnergroup default
+
+# 启动 Runner
+./run.sh
+```
+
+### 3. 获取 Runner Token
+
+1. 访问 Gitea 仓库：http://192.168.120.110:4000/damai/readflow
+2. 进入 Settings → Actions
+3. 点击 "Add runner"
+4. 复制 Token
+
+### 4. 验证 Runner
+
+访问 Gitea 仓库的 Actions 页面，应该能看到注册的 Runner。
+
+### 5. 触发编译
+
+推送标签触发编译:
+
+```bash
+cd /Users/rong/.openclaw/workspace/readflow
+git tag -a v0.2.1 -m "Release v0.2.1"
+git push origin v0.2.1
+```
+
+---
+
+## 工作流文件
+
+工作流文件位于：`.gitea/workflows/release.yml`
+
+支持的平台:
+- ✅ Windows (x86_64-pc-windows-gnu)
+- ✅ Linux (x86_64-unknown-linux-gnu)
+- ✅ macOS (x86_64-apple-darwin)
+
+---
+
+## 故障排除
+
+### Runner 无法连接
+
+检查 Gitea 配置:
+```ini
+[actions]
+ENABLED = true
+DEFAULT_ACTIONS_URL = github
+```
+
+### 编译失败
+
+检查 Runner 是否安装了必要的依赖:
+```bash
+# macOS
+brew install rust mingw-w64
+
+# Linux
+sudo apt-get install rustc mingw-w64
+```
+
+### 查看日志
+
+访问 Gitea 仓库的 Actions 页面查看编译日志。
+
+---
+
+## 快速开始
+
+### 方案 1: 使用 Docker Runner (推荐)
+
+```bash
+docker run -d \
+  -e GITEA_INSTANCE_URL=http://192.168.120.110:4000 \
+  -e GITEA_RUNNER_REGISTRATION_TOKEN=<TOKEN> \
+  -e GITEA_RUNNER_NAME=docker-runner \
+  -v /var/run/docker.sock:/var/run/docker.sock \
+  ghcr.io/gitea/act_runner:latest
+```
+
+### 方案 2: 本地安装 Runner
+
+参考上面的安装步骤。
