 ## why gosvelt ?
 ### fullstack integration of svelte
+ yeah, gosvelt will compile, group, and serve svelte pages.  
+ A Svelte or AdvancedSvelte handler will give you a **svelte map** wich contain "js" and "css" URLs and you can add to this map your own attributes that will be rendered on the html template (note: if you add for example a "test" element to the map, you have to add the `&{test}` element in the html template)
 ```golang
 func main() {
 	r := gosvelt.New()
 
 	r.Svelte("/", "./static/App.svelte", func(c *gosvelt.Context, svelte gosvelt.Map) error {
-		return c.Html(200, "./static/index.html", svelte)
+		return c.Html(200, "./static/index.html", svelte) // html template
 	})

 ### cool way to made sse
+ there are actyally to way to use sse in gosvelt: the **context** way wich is in a context and can use channels declared in the handler. And the **handler** way wich is an handler function and use channels who are declared outside the handler.
