+# .worktreeinclude
+
+Add `.worktreeinclude` at the root of your source checkout to copy local configuration into new [Git worktrees](/docs/worktrees). Paseo copies matching gitignored files before setup, terminals, and the first Agent start.
+
+## Copy your local configuration
+
+For a project whose `.gitignore` includes `.env` and `config/*.local.json`, create this `.worktreeinclude`:
+
+```gitignore
+.env
+config/*.local.json
+```
+
+When you create a worktree through Paseo, an existing `.env` and matching files such as `config/dev.local.json` are copied to the same relative paths in the new worktree. Their contents stay out of Git.
+
+Commit `.worktreeinclude` to share the patterns with your team. Each teammate supplies their own ignored files in the checkout they create worktrees from.
+
+## Pattern syntax
+
+Use gitignore syntax, with one pattern per line. Comments start with `#`. Prefix a pattern with `!` to exclude a match:
+
+```gitignore
+# Local environment and configuration
+.env
+config/*.local.json
+!config/production.local.json
+```
+
+A pattern only selects files that Git already ignores. Adding a path here does not ignore it, so also configure `.gitignore` when needed. Tracked files and untracked files that Git does not ignore are excluded.
+
+## When files are copied
+
+The built-in `worktree-include` plugin reads the file from the checkout you create the worktree from. That source can itself be another worktree. Keep the plugin enabled for copying to run.
+
+- Without `.worktreeinclude`, the plugin copies nothing.
+- Matching files must exist in the source checkout.
+- Existing destination files are skipped, preserving their contents.
+- Copies happen during creation, with no ongoing synchronization between checkouts.
+- A copy error aborts creation and removes the new worktree. Avoid including symlinked directories or nested repositories, which cannot be copied as files.
+
+## Run commands during setup
+
+Use `.worktreeinclude` for files that already exist locally. Use a [setup hook](/docs/worktrees#setup-and-teardown) to install dependencies, generate files, or fetch secrets:
+
+```json
+{
+  "worktree": {
+    "setup": "npm ci"
+  }
+}
+```
+
+Put this configuration in `paseo.json` on the base branch used for the new worktree. Copied files are available when setup runs.

+# .worktreeinclude
+
+在源检出的根目录添加 `.worktreeinclude`，将本地配置复制到新的 [Git worktree](/docs/worktrees)。Paseo 会在 setup、终端和首个 Agent 启动之前复制匹配的 Git 忽略文件。
+
+## 复制本地配置 {#copy-your-local-configuration}
+
+如果项目的 `.gitignore` 包含 `.env` 和 `config/*.local.json`，创建以下 `.worktreeinclude`：
+
+```gitignore
+.env
+config/*.local.json
+```
+
+通过 Paseo 创建 worktree 时，已有的 `.env` 和 `config/dev.local.json` 等匹配文件会被复制到新 worktree 中的相同相对路径。文件内容仍不会纳入 Git。
+
+提交 `.worktreeinclude`，与团队共享这些模式。每位团队成员在用于创建 worktree 的检出中提供自己的忽略文件。
+
+## 模式语法 {#pattern-syntax}
+
+使用 gitignore 语法，每行一个模式。注释以 `#` 开头。模式前加 `!` 可排除匹配项：
+
+```gitignore
+# Local environment and configuration
+.env
+config/*.local.json
+!config/production.local.json
+```
+
+模式只会选择 Git 已忽略的文件。在此添加路径不会使 Git 忽略该文件，需要时还应配置 `.gitignore`。已跟踪的文件和未被 Git 忽略的未跟踪文件都不会被复制。
+
+## 文件复制时机 {#when-files-are-copied}
+
+内置的 `worktree-include` 插件从用于创建 worktree 的检出读取该文件。源检出也可以是另一个 worktree。保持该插件启用才能执行复制。
+
+- 没有 `.worktreeinclude` 时，插件不会复制任何文件。
+- 匹配的文件必须存在于源检出中。
+- 目标中已存在的文件会被跳过，保留原有内容。
+- 复制发生在创建期间，之后不会在检出之间持续同步。
+- 复制错误会中止创建并删除新 worktree。避免包含符号链接目录或嵌套仓库，因为它们无法作为文件复制。
+
+## 在 setup 期间运行命令 {#run-commands-during-setup}
+
+使用 `.worktreeinclude` 复制本地已有文件。使用 [setup 钩子](/docs/worktrees#setup-and-teardown) 安装依赖、生成文件或获取密钥：
+
+```json
+{
+  "worktree": {
+    "setup": "npm ci"
+  }
+}
+```
+
+将此配置放入新 worktree 所用基准分支的 `paseo.json` 中。setup 运行时，复制的文件已可使用。
