Installing older mods with CKAN

[PartiallyBurnt]

I've only just reinstalled KSP after a long break. I was about to download Scatterer, but CKAN says it's made for version 1.5.1; meanwhile I've seen a lot of people use Scatterer with 1.6. I want to know a way to install this (and a couple other) mods manually. What folders do I stick them in? Where do I find all the dependencies?

In CKAN, you can go to the Settings menu and select Compatible KSP Versions.  This lets you select the KSP versions it will display for mod compatibility.  For example, I am running KSP v 1.6.1, but I have checked 1.6, 1.5, and 1.4,  so CKAN will show me mods compatible with those versions. If you are considering running a mod that is not specifically compatible with your version of KSP,  there's always the risk it will not work correctly, so should only be done if you understand the risks.
