+#Return translated string using translations files
+
+#category and lang are set to current page.id and page.lang, but they can
+#also be set manually to get translations for global layout and urls.
+#Example: {% translate button-wallet layout %} will return the
+#translated button-wallet string for the global layout file
+
+#dynamic variables can be used as arguments
+#Example: {% translate menu-{{id}} %}
+
+#urls and anchors are automatically replaced and translated. 
+#Example: #vocabulary##[vocabulary.wallet] is replaced by
+#/en/vocabulary#wallet when the page is in english or
+#/fr/vocabulaire#porte-monnaie when the page is in french.
