Why and how did paper come into use?

In ancient China, people wrote on bamboo or silk, but it is hard to carry with and store, so the eunuch Cai Lun started to think how to improve the procedure of making paper.
Bark, rag or even broken fishing nets were soaked in the water for several days. Then they were pounded, boiled and then put it on the mat to dried. Then a piece of paper was finished.
