+### Git Credential Helper
+
+QuiCommit can act as a Git credential helper to securely store and retrieve
+Personal Access Tokens (PATs) via the system keyring. The `credential` command
+is hidden from `--help` because it is invoked automatically by Git, not by end
+users.
+
+#### Setup
+
+Register QuiCommit as a credential helper for Git:
+
+```bash
+# Use the default QuiCommit config
+git config --global credential.helper quicommit
+
+# Or specify a custom config file
+git config --global credential.helper "quicommit --config /path/to/config.toml"
+```
+
+You can also limit the helper to a specific host:
+
+```bash
+git config --global credential.https://github.com.helper quicommit
+```
+
+#### How It Works
+
+When Git needs credentials (e.g. pushing to a remote), it calls the helper
+following the [gitcredentials protocol](https://git-scm.com/docs/gitcredentials):
+
+1. **`get`** — Git asks QuiCommit for a stored PAT matching the requested host.
+   QuiCommit searches all configured profiles in the keyring and returns the
+   PAT (plus username) if found.
+2. **`store`** — After a successful authentication (e.g. you entered a PAT in
+   the Git prompt), Git asks QuiCommit to save it. The PAT is stored in the
+   system keyring, bound to the matching profile.
+3. **`erase`** — Git asks QuiCommit to delete a stored PAT for the given host.
+
+Host names are mapped to canonical service names (`github.com` → `github`,
+`gitlab.com` → `gitlab`, `bitbucket.org` → `bitbucket`, etc.). Unknown hosts
+are used as-is.
+
+#### Removing Stored Credentials
+
+To remove a stored PAT, you can either use Git's built-in mechanism:
+
+```bash
+echo "protocol=https
+host=github.com" | git credential reject
+```
+
+Or remove it via the profile token management command:
+
+```bash
+quicommit profile token
+```
+

+### Git 凭据助手（Credential Helper）
+
+QuiCommit 可以作为 Git 凭据助手，通过系统密钥环安全地存储和读取个人访问令牌（PAT）。
+`credential` 命令在 `--help` 中是隐藏的，因为它由 Git 自动调用，无需用户手动执行。
+
+#### 配置方法
+
+将 QuiCommit 注册为 Git 凭据助手：
+
+```bash
+# 使用默认的 QuiCommit 配置
+git config --global credential.helper quicommit
+
+# 或指定自定义配置文件路径
+git config --global credential.helper "quicommit --config /path/to/config.toml"
+```
+
+也可以仅对特定主机启用：
+
+```bash
+git config --global credential.https://github.com.helper quicommit
+```
+
+#### 工作原理
+
+当 Git 需要凭据（例如推送到远程仓库）时，会按照
+[gitcredentials 协议](https://git-scm.com/docs/gitcredentials) 调用助手：
+
+1. **`get`** — Git 向 QuiCommit 请求与目标主机匹配的已存储 PAT。
+   QuiCommit 在所有已配置的 profile 中搜索密钥环，找到则返回 PAT（及用户名）。
+2. **`store`** — 认证成功后（例如你在 Git 提示中输入了 PAT），Git 要求
+   QuiCommit 保存该凭据。PAT 将存入系统密钥环，并与匹配的 profile 绑定。
+3. **`erase`** — Git 要求 QuiCommit 删除指定主机的已存储 PAT。
+
+主机名会被映射为规范化的服务名（`github.com` → `github`、`gitlab.com` →
+`gitlab`、`bitbucket.org` → `bitbucket` 等），未知主机则原样使用。
+
+#### 删除已存储的凭据
+
+可以通过 Git 内置机制删除已存储的 PAT：
+
+```bash
+echo "protocol=https
+host=github.com" | git credential reject
+```
+
+也可以通过 profile 令牌管理命令删除：
+
+```bash
+quicommit profile token
+```
