The only issue with projects like LineageOS is that the camera usually sucks because the full fat camera driver isn’t released to the public, it’s only the basic driver. The camera can still take photos but all of the features you’ve become accustomed to are not there. This was my experience and what the LineageOS team said during the Samsung S5-S8 days.
Usenet requires an indexer and a provider. An indexer indexes content. A provider is a server that hosts the content. Content is split into 1MB chunks.
The manual way. You look for content you want on the website of the indexer and download the nzb file. You download the nzb file, which a list of the 1MB chunks and put it in your usenet download software. The downloader then downloads it.
The automated way. There is a software suite called *arr. It’s not exclusive to Usenet; you can also use it with torrents. You search for the content you’re interested in and the software does the rest.
Trash-guides and servarr are popular guides.
