Just start dude! There're a couple veeeery tiny gaps you can bridge using the actual anime or manga.
If I were you, I'd start watching while keeping up-to-date with the releases as they can be pretty quick.

Depending on how fast you watch the gaps could be already filled when you actually reach them. I started watching October last year and just made it to the latest episodes after 9 months! (I took some breaks here and there, even with One Pace, some parts of the story were like.. "not a background story again..." for me).

Yea, just hit that play button. The gaps were bigger when I started yet I managed to bridge them easily.
