I need to write a summary about how cross country skiing is played?

Cross-country skiing is a form of ski touring in which participants propel themselves across snow-covered terrain using skis and poles. The activity is popular in many places with large snowfields, primarily Northern Europe, Canada, and Alaska.Recreational cross-country skiing is most frequently known as touring. Some skiers stay out for extended periods using tents and equipment similar to bushwalkers/hikers, whereas others take relatively short trips from ski resorts on maintained trails. In some countries, organizations maintain a network of huts for use by cross-country skiers in wintertime.
