-Use the `base64Decode` function to decode responses from APIs. For example, the result of this call to GitHub's API contains the base64-encoded representation of the repository's README file:
-
-```text
-https://api.github.com/repos/gohugoio/hugo/readme
-```
-
-To retrieve and render the content:
-
-```go-html-template
-{{ $u := "https://api.github.com/repos/gohugoio/hugo/readme" }}
-{{ with resources.GetRemote $u }}
-  {{ with .Err }}
-    {{ errorf "%s" . }}
-  {{ else }}
-    {{ with . | transform.Unmarshal }}
-      {{ .content | base64Decode | markdownify }}
-    {{ end }}
-  {{ end }}
-{{ else }}

----
-
-To customize the printing of the JSON, pass an options map as the first
-argument. Supported options are "prefix" and "indent". Each JSON element in
-the output will begin on a new line beginning with *prefix* followed by one or
-more copies of *indent* according to the indentation nesting.
-
-```go-html-template
-{{ dict "title" .Title "content" .Plain | jsonify }}
-{{ dict "title" .Title "content" .Plain | jsonify (dict "indent" "  ") }}
-{{ dict "title" .Title "content" .Plain | jsonify (dict "prefix" " " "indent" "  ") }}
-```
-
-## Options
-
-indent
-: (`string`) Indentation to use. Default is "".
-
-prefix
-: (`string`) Indentation prefix. Default is "".
-
-noHTMLEscape
-: (`bool`) Disable escaping of problematic HTML characters inside JSON quoted strings. The default behavior is to escape `&`, `<`, and `>` to `\u0026`, `\u003c`, and `\u003e` to avoid certain safety problems that can arise when embedding JSON in HTML. Default is `false`.
