Ya start reading from where you left off in the anime. But keep in mind that some things might become a little more clear if you read the corresponding manga chapters. Also, things you forgot about will be refreshed in your mind if you reread chunks of the manga. I started from where I left off in the anime, but have read around 150 of the other chapters in total and got some insight I never really noticed or didn't realize was important until I read it in the manga.
However, there are things in the anime that are more clear than in the manga. One example is the rock techs used by Oonoki and Akasuchi to escape Zetsu's spore jutsu at the summit. In the manga it was really brief but longer in the anime.
Bottom line, the anime may be better in some instances, but the manga is far greater in general and it is much MUCH easier to reference a scene/ battle by linking a manga chapter rather than linking an anime episode. So just read from where you left off in the anime but take some time to read some important sections from the manga like big battles or scenes of great importance. One example would be chapter 467 (I can remember it by heart) where tobi declares war on the 5 countries. But in general, don't waste your time starting from scratch.
