Add documentation about how to bind multiple instances of the same query parameter to a slice.
Use this UT as a reference (if it is possible make a more real example than this 😉)

func TestBindSlices(t *testing.T) {
	e := New()
	req := httptest.NewRequest(GET, "/?str=foo&str=bar&str=foobar", nil)
	rec := httptest.NewRecorder()
	c := e.NewContext(req, rec)
	result := struct {
	

In my workflow it would be more intuitive to have a additional "save"-Button at the end of the page to save the new recipe.
At the moment I have to scroll back to the top and - in some cases - I have to be careful not to click the "tasks"-button one above (see screenshot).
