Help in CUI

Hi, I recently started to remodel some plugins for myself, add sounds, change the interface.
Even wrote the plugin redirecting commands:
/kits => /kit
/help => /info
And I'm not going to stop, but can help me?
I need the material:
How to create a user interface?
[DOUBLEPOST=1515360554][/DOUBLEPOST]And
Cui - Text UI?
Gui - Graphic?
[DOUBLEPOST=1515360619][/DOUBLEPOST]I do not know where to start, my eyes run out.
So many opportunities, but I miss everything(

 

Simple example (very old plugin):

Code:

void Rules(BasePlayer player)
        {
            CuiHelper.DestroyUi(player, "RulesGUI");
            var elements = new CuiElementContainer(); //Êîíòåéíåð äëÿ ýëåìåíòîâ ÃÓÈ
            //-------------ÎÒÐÈÑÎÂÊÀ ÃÓÈ-------------
            var mainName = elements.Add(new CuiPanel
            {
                FadeOut = 1.0f,
                Image =
                {
                    Color = "0.1 0.1 0.1 0"
                },
                RectTransform =
                {
                    AnchorMin = "0.3445 0.115",
                    AnchorMax = "0.6395 0.135"
                },
                CursorEnabled = false
            }, "Hud", "RulesGUI");
            elements.Add(new CuiElement
            {
                FadeOut = 1.0f,
                Parent = "RulesGUI",
                Components =
                    {
                        new CuiRawImageComponent
                        {
                            FadeIn = 1.0f,
                            Url = "http://i.imgur.com/nBtBdI1.png",
                            Sprite = "assets/content/textures/generic/fulltransparent.tga"
                        },
                        new CuiRectTransformComponent
                        {
                            AnchorMin = "0 0",
                            AnchorMax = "1 1"
                        }
                    }
            });
            //-------------Âûâîä íà ýêðàí-------------
            CuiHelper.AddUi(player, elements);
            //-------------ÎÒÐÈÑÎÂÊÀ ÃÓÈ-------------
        }

Then every where you want: Rules(player);
