[ASK] How to configure RouterBOARD RB750Gr2 as Switch?

Hello, can you help me how to setup My RouterBOARD RB750Gr2 as Switch?? Tutorial given on Mikrotik Wiki (http://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features) is very confusing for people like me.. i just want ‘To the point’ Tutorial, not a Complex Tutorial (i mean, just give Tutorial which Dummies can understand too).

Here’s the picture of my Mikrotik:
