The Rugby World Cup kicked off in England a week ago and has already captured the imagination of fans and newcomers to the sport all around the world.

Japan’s opening-round heroics against South Africa – one of the biggest upsets in sporting history – was an occasion to savor and will be talked about for years to come.

The hosts stuttered to victory against Fiji in the tournament opener, but still hold hope of lifting the famous Webb Ellis Trophy on home soil.

Uruguay, with a team consisting of just three professional players, put in a tremendous performance against Wales and Argentina gave New Zealand – the tournament favorites – a real run for their money.

If you are inspired and captivated by your country’s players or as a neutral enjoyed one of those rare moments David toppled Goliath, but are still a bit confused about just what is happening on the pitch then CNN is here to help.

With the help of London Irish Rugby Football Club, CNN has put together a series of videos with everything you need to know about the key components of the sport.

The first in our ‘CNN Sport explains’ series is kicking. You will find out about place kicking, the up and under, the grubber kick, the chip and chase and drop goals.

Next is the scrum, one of the most fundamental and technical areas in rugby. London Irish take us through the different positions – from hookers to number eights.
