Installation question

Hi. I have the Linksys WRT1900ACSv2 router, which is supported by LEDE.

I have several questions. First, when searching for the router to see if it's supported, I see that it is.

I've seen other forum topics on the v2, but I want to make sure it's supported, because the download looks like it's for the acsv1 and I want to make sure I don't brick my router.

Also, I'm familiar with flashing because I've used dd-wrt, but I have a question about packages. For example, I want ad blocking. Is everything I need included in the download of LEDE? Or do I separately..."install" I'm just very new to this router OS and I don't know my way around yet, or where to find the information understandable to a newbie.

Any guidance appreciated.

Regarding the packages: You have to install them seperately.
