i swapped out a 15t for a 14t recently and all i did was loosen the 17mm pinch bolt and slacken the rear hub until the chain was fully lossened , removed the front sprocket cover,undid the 14mm nut ,pulled the chain off the sprocket and removed it.
instalation was the reverse.

will i need a special chain tentionor tool?

You can get away with using a long flathead screwdriver as a drift and knocking the hub round with a hammer, it's what I use until I buy the tool

Just be carefully you don't mash the teeth on the hub if using the hammer and screwdriver method

just buy the tool, it's only £16 quid and it beats the £60+ you'll have to pay when the screwdriver messes up the teeth on the adjuster.
