+
+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 }}
+  {{ errorf "Unable to get remote resource %q" $u }}
+{{ end }}

+
+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`.
