VLAN out of the box, or?

Worked with another router for long time, "Edge router" where configuration is simple. I now used some time with the RB750Gr3 ( MT7621 ) router and Winbox.

Have read so much about the configuration and hardware in the router. The https://wiki.mikrotik.com and forum have nice information.
When it comes to setup VLAN, for me it is a complete mess. So many ways to do it wrong. The more I read about VLAN on MT, the more confused I get.
Problem is the hardware and winbox, all can be done, no restriction, no grayed out option.

It will always be the user there must know what he/she are doing, i know that. But for now VLAN in MT is a mess i think.
Suggestion to MT clean up your documentation and give some clean working example on different switch chips for VLAN.
As i can read the MT7621 is not supporting hardware VLAN switching, so software/cpu must do it.

I have read this many times, nice written. But it can't be the way for all hw, or?

This is wrong or confusing information:
Other devices with built-in switch chip (Note: This type of configuration should be used on RouterBOARD series devices, this includes RB4xx, RB9xx, RB2011, RB3011, hAP, hEX, cAP and other devices. )

- ...vlan-mode=secure vlan-header=add-if-missing ->Can't be done at the MT7621 in ROS 6
The switch chip MT7621 can't be configured as the description in the printed information, in RouterOS 6. Look like it is fixed in V 7.x

Please fix the documentation, it confusing to be new to a product and have the wrong information. MT router is a real complicated thing, and the user must know the printed information is correct.

I found so many wrong printed information, not easy to understand when the information is confusing and wrong.

A correct and clean example for a RB750Gr3 / with a MT7621 switch chip. Where CPU load is minimum and speed at max. will be so nice:-)

The router have 5 port.
Port 1: WAN, DHCP client, or static ip.
port 2: VLAN 10, out remove tag, in add tag. DHCP server segment 192.168.10.0/24
port 3: VLAN 20, out remove tag, in add tag. DHCP server segment 192.168.20.0/24
port 4: VLAN 30, out remove tag, in add tag. DHCP server segment 192.168.30.0/24
port 5: TRUNK for VLAN 10,20,30. Tagged.
