I want generate a 5 Volt, around 55 Hz(50-60) square wave with NE555S-13

In the datasheet I found the configuration for Astable Operation which I assume is what I want

But then I found out that NE555S-13 is featured in the web simulator: https://www.falstad.com/circuit/

The problem is that in falstad the configuration for square generation is very different and I don't know what to make of it
