+#### Use Functions (Experimental)
+
+InkPaper defines a minimal set of functions that can be used in HTML pages (except for `.md` source files), such as
+
+``` yaml
+{{ readFile "path/to/file" }}
+```
+
+This will read the content of the file `path/to/file` and include it in the page without any processing.
+
+For file-related functions, when executed in the `source` directory, the file path is relative to the `source` directory; when executed in other directories, the file path is relative to the theme (such as `theme`).
+
+See the source file `funcs.go` for a list of all functions.

+#### 使用函数（实验性）
+
+纸小墨定义了一个最小的函数集合，可在 HTML 页面（除 `.md` 源文件以外）中使用，如
+
+``` yaml
+{{ readFile "path/to/file" }}
+```
+
+将读取 `path/to/file` 文件的内容并（不做任何处理地）包含入页面中。
+
+对于文件相关的函数，当在 `source` 下执行时，文件路径相对于 `source` 目录；当在其他目录下执行时，文件路径相对于主题（如 `theme`）目录。
+
+所有函数列表见源文件 `funcs.go` 文件。
