Any time I can spread the good word of markdown, I’m happy to do so.

By the way, I don’t know which ones, but many Lemmy clients have buttons to simplify common markdown (links and images are notoriously easy to mess up). On my client, Connect, there are a row of buttons below the text entry area to help with formatting and syntax. It’s also how I upload images if posting from my local client rather than somewhere already online.

I don’t know your client, but it might be worth checking whether these buttons exist for you so you don’t have to remember / look up the syntax.
