+		"This is standard way of routing and requires that you have a router on the server side also.
+		Browser while approaching application will always send full URL to the server.
+		This is useful when you want to do SSR (server side rendering). SSR is needed for bots only (like Google, Facebook etc.).
+		So use it for these parts of application which are public and you want them to be crawlable/readable for bots."
+		<h2$hash.gradient> "Hash based router"
+		<imba-code.no-code url="example.com/#/with/hash/url">
+		"Hash is meant for browser only. This way of routing doesn't require server at all.
+		Very good for decreasing unnecessary request.
+		Use it for dashboards and other functionalities which are not meant to be shown for anonymous user."
+		<br>
+		<br>
+		"Another use case is making standalone application which you can access even without internet - receive and
+		copy further. In other words save to disk like 25y ago. Good for making tool applications - processing
+		information which is mostly delivered by the user."
+		<br>
+		<br>
+		"For the same reason it's good for interfaces of distributed applications."
+		<pro-tip>
+			"If you will treat Hash as only store of data for your application your application already is distributed and trully serverless. Just compile it to one html file."
+
+		<h2$both.gradient> "URL and hash together"
+		<imba-code.no-code url="example.com/with/normal/url/#/and/hash/addition">
+		"Good idea is to mix both mentioned approaches together - and attach hash router to your standard application.
+		In hash you can store information which is tighted to the client. For example interface configuration customised by the user."
+		<pro-tip>
+			"There's no conflict between url and hash - so you could use imba router for url and pro-router for hash."
+
+		<h2$var.gradient> "Url variables based router*"
+		<imba-code.no-code url="example.com/?view=with&variabled=url">
+		"URL variables are old standard which is going out of common use - considered ugly to read. Still the good thing is
+		it's widely supported. It's supported by browsers and backends. It's great oportunity. You could use it in many ways.
+		For example copy values from URL to your API requests. This would give easy way (for authorised only) to modify behaviour of your backend.
+		Helpful for testing, debugging or switching feature flags."
