-## Usage
-
-It is possible to create a resource directly from the template using `resources.FromString` which takes two arguments, the target path for the created resource and the given content string.
-
-The result is cached using the target path as the cache key.
-
-The following example creates a resource file containing localized variables for every project's languages.
-
-```go-html-template
-{{ $string := (printf "var rootURL = '%s'; var apiURL = '%s';" (absURL "/") (.Param "API_URL")) }}
-{{ $targetPath := "js/vars.js" }}
-{{ $vars := $string | resources.FromString $targetPath }}
-{{ $global := resources.Get "js/global.js" | resources.Minify }}
-
-<script src="{{ $vars.Permalink }}"></script>
-<script src="{{ $global.Permalink }}"></script>
-```
