Use MangaUpdates so you can know if the manga you want to read is scanlated.https://www.mangaupdates.com/index.html
Then you can go to the scanlator site to download the chapter or just use MangaDex to read it online.https://mangadex.org/
If you like infinity scrolling I recommend this script here. MangaDex has a infinity scrolling option but it also works in various other manga sites.https://greasyfork.org/en/scripts/692-manga-loader
Madokami is for downloading manga, and I don't think they will open registrations soon. You can use Nyaa but sometimes there aren't seeders, and Madokami also has a lot of official rips and old/deleted files you can't find anywhere or files that are available in only other sekrit clubs so it's pretty good if you read a lot of niche stuff. Since you don't read too much manga you probably won't need it, MangaDex + MangaUpdates + Google will probably be good enough for you. Just keep in mind if you're going to read from random manga sites, try to avoid the ones that add watermarks to the manga pages and the ones that resize the files.
If you want to get into a secret club for manga, try AnimeBytes, it's pretty good for official stuff or complete manga.
