The `os.ReadFile` function attempts to resolve the path relative to the root of your project directory. If a matching file is not found, it will attempt to resolve the path relative to the [`contentDir`](/getting-started/configuration#contentdir). A leading path separator (`/`) is optional.

With a file named README.md in the root of your project directory:

```text
This is **bold** text.
```

This template code:

```go-html-template
{{ readFile "README.md" }}
```

Produces:

```html
This is **bold** text.
```

Note that `os.ReadFile` returns raw (uninterpreted) content.
