Hit the nail on the head.Hello waz...
There's no mystery to it. You remove any metal clamps, plastic, rockwool, small rocks, etc. Rinse the plants well in warm tap water and put them into the tank per the instructions that come with the plants. I prefer to do my planting in the middle of a water change. It makes the job much easier.

The reason I asked this is because I heard people say that you need to isolate the plants for a certain amount of time before you should introduce it to your tank to avoid killing any fish.
