Hello fellow patient gamers, this is a cheeky self-plug for !freegames@feddit.uk, a community I’ve created to post limited-time full-game free giveaways. The reward for being patient is that sometimes you get freebies; post them here if you spot them first, or comment to say whether it’s a must play for everyone or if zero cost is still too expensive!
tl:dr; rss is a standard format for updates (think title, description, link). Think about rss updates as emails and an rss reader as an email inbox
How and where do you subscribe to rss?
You can use one of the bunch of RSS feed readers to do that. I haven’t use it for years (basically since I lost everything I had on Google reader) so I cannot recommend you any apps
