Linking to first page of blog posts from custom home page

Hi, I’ve been playing around with implementing a custom home page, by following this help topic, but there’s something I’m not understanding: how can I link from there to my normal page of posts?

Say I make a welcome page, but I want people to be able to click through to my pages of blog posts; if I include a link to it links to the second page of my blog, but seems to send me back to the custom home page, not the first page of blogposts as intended.

(All help appreciated. I’m prepared to delete this topic in a heartbeat if I’m missing something super obvious!)
