 ## Copy local files with .worktreeinclude
 
-Use [`.worktreeinclude`](/docs/worktrees/worktreeinclude) to copy selected gitignored files, such as `.env`, from your source checkout before setup runs.
+Create `.worktreeinclude` at the root of your source checkout to copy selected gitignored files into new worktrees:

+Patterns use gitignore syntax. A file must match `.worktreeinclude` and be gitignored to be copied. Tracked files are never copied, and existing destination files are never overwritten. Without `.worktreeinclude`, no local files are copied. Symlinked directories and nested repositories inside an included path cause the copy to fail and abort worktree creation.
+
+The built-in `worktree-include` plugin copies from the checkout you create the worktree from, including when that checkout is another worktree. Copying finishes before setup, terminals, and the first agent. A copy failure aborts creation and removes the new worktree. Copies use copy-on-write clones on APFS and btrfs when supported, with a regular copy elsewhere.

-# .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。
