The best way to start learning golf is by having a lesson given by a PGA professional at either your local golf club or driving range.
Many will offer free or discounted lessons for beginners, especially at the start of the season, either as part of a group (usually for juniors) or on a one to one basis.
The Instruction Section on Lets' Get Golfing is to support the teaching you will receive from a PGA professional, to help you remember the 'basics' which are all important and getting these right will have a profound positive effect on your future golf abilities.
