Estimating the Product Backlog
Before the Team can start working on Stories, Team Members have to estimate them relative to each other (i. e. a Story estimated with 2 points presumably takes twice as much effort as a 1 point Story). In order for this to be possible, the Product Owner needs to provide a sufficient description and explanation of the Story. Once Stories are pulled to a Sprint, they may not be changed any further. Therefore, the Product Owner should always be present for estimation and explain the Stories to the team (and adjust the **it's** description and scope if necessary).
In the last sentence of that paragraph, "it's" seems to be superfluous.
