I'm writing a text in which I'd like to explain a concept. In order to explain that, I must explain another concept first which is necessary to understand the first one.
After explaining this other concept first, I'd like to say something like "Now that we've clarified this, we can talk about ...". I'm looking for an expression for the first half of this sentence. I know expressions like
"With that out of the way, ..."
"Now that we've agreed on this, ..."
"Now that we've settled that, ..."
The point I'd like to get across is that now that we have a common understanding of how the first thing works, we can move on and discuss X.
The examples I gave are a little harsh to me, but maybe okay. I'm just wondering if there are more options here.
