+External Links allow an end user to specify by means of a jinja template a link that when displayed upon an items display page will add a button with a hyperlink to the url provided. External links can be assigned to: devices and software. This includes both at the same time.
+
+
+## Create a link
+
+- Software context is under key `software`
+
+- Device context is under key `device`
+
+To add a templated link within the `Link Template` field enter your url, with the variable within jinja braces. for example to add a link that will expand with the devices id, specify `{{ device.id }}`. i.e. `https://domainname.tld/{{ device.id }}`. If the link is for software use key `software`. Available fields under context key all of those that are available at the time the page is rendered.
