+### Publish to ClawHub / OpenClaw
+
+This repository now supports publishing each `skills/baoyu-*` directory as an individual ClawHub skill.
+
+```bash
+# Preview what would be published
+./scripts/sync-clawhub.sh --dry-run
+
+# Publish all changed skills from ./skills
+./scripts/sync-clawhub.sh --all
+```
+
+ClawHub installs skills individually, not as one marketplace bundle. After publishing, users can install specific skills such as:
+
+```bash
+clawhub install baoyu-image-gen
+clawhub install baoyu-markdown-to-html
+```
+
+Publishing to ClawHub releases the published skill under `MIT-0`, per ClawHub's registry rules.

+### 发布到 ClawHub / OpenClaw
+
+现在这个仓库支持把每个 `skills/baoyu-*` 目录作为独立 ClawHub skill 发布。
+
+```bash
+# 预览将要发布的变更
+./scripts/sync-clawhub.sh --dry-run
+
+# 发布 ./skills 下所有已变更的 skill
+./scripts/sync-clawhub.sh --all
+```
+
+ClawHub 按“单个 skill”安装，不是把整个 marketplace 一次性装进去。发布后，用户可以按需安装：
+
+```bash
+clawhub install baoyu-image-gen
+clawhub install baoyu-markdown-to-html
+```
+
+根据 ClawHub 的 registry 规则，发布到 ClawHub 的 skill 会以 `MIT-0` 许可分发。
