OP-AMP PT100 signal conditioner

~~Hi all,~~
~~Long time lurker here on this forum, and now I finally feel the need to ask a probably really simple question but one that I cannot wrap my head around...~~
~~Can someone take me through how this circuit works, especially as it's intended to be used as a PT100 conditioner.~~

How does this circuit work, especially considering that it's intended to be used as a PT100 conditioner?
