+There's no documentation yet, have a look at https://github.com/vlang/vtalk for an example of a simple vweb app.
+
+`vtalk.v` contains all GET and POST actions.
+
+```
+pub fn (app mut App) index() {
+	posts := app.find_all_posts()
+	$vweb.html()
+}
+
+// TODO ['/post/:id/:title'] 
+// TODO `fn (app App) post(id int)` 
+pub fn (app App) post() {
+	id := app.get_post_id() 
+	post := app.retrieve_post(id) or {
+		app.vweb.redirect('/') 
+		return 
+	}
+	comments := app.find_comments(id)
+	show_form := true 
+	$vweb.html()
+}
+
+```
+
+`index.html` is an example of the V template language:
+
+```
+@for post in posts 
+	<div class=post>
+		<a class=topic href="@post.url">@post.title</a> 
+		<img class=comment-img> 
+		<span class=nr-comments>@post.nr_comments</span> 
+		<span class=time>@post.time</span>
+	</div>
+@end
+```
+
+`$vweb.html()` compiles an HTML template into V during compilation, and embeds the resulting code in current action.
+
+That means that the template automatically has access to that action's entire environemnt.
