+# template
+A minimal polyfill for `<template>`.
+
+## Known limitations
+
+### Template nodes in main document are upgraded after `DOMContentLoaded`
+
+The first timepoint in which the polyfill can be certain the main document is loaded is `DOMContentLoaded`.
+As such, we use this timepoint to bootstrap any `<template>` as defined in the main document.
+This means that any scripts in the main document that run before this event (e.g. inline scripts) will not have the properly upgraded templates.
+Instead, listen for `DOMContentLoaded` yourself and only after that interact with any `<template>` in the main document.
