As a novice you should educate yourself on the basics of forex by learning the terminologies. You can find this information online.
After that, you can register with a Capital Markets Authority (CMA) licensed forex broker (the ones authorized by the Kenyan government) see the list here: https://licensees.cma.or.ke/licenses/5/
After registering with a forex broker, proceed to open a Demo Account (an account for practicing how to trade with fake money), do not rush into opening a live account yet.
You can begin to experiment with the demo account and everything you had learnt about forex terminologies will begin to make sense once you are practicing with a demo.
Keep learning with the demo account until you are sure you have understood how to trade and make a profit, and how to manage your risk (it might take a couple of months).
After the demo account, you can proceed to open a live account but only deposit an amount of money you can afford to lose in to the live account.
The live account will teach you how to manage your emotions of fear, greed etc. which was not present on the demo account because you were not trading with real money.
When trading with a live account, only trade small lot sizes of 0.01 and once again only trade with money you can afford to lose and not shed a tear.
