Citing one paper in consecutive paragraphs in a thesis I dedicated one subsection of my thesis to a very new topic from a 2020 paper so I had only one reference. I wrote the subsection in this way:

paragraph 1: Introduction to the concept of X and the framework
containing five dimensions
paragraph 2: dimension 1
paragraph 3: dimension 2
paragraph 4: dimension 3
paragraph 5: dimension 4
paragraph 6: dimension 5
paragraph 7: Wrap up and conclusion

Everything has been summarised (not copied) from one 2020 paper. My question is: what is the best way to cite that paper? Does it make sense to add one sentence to paragraph 1 and say that contents of this subsection is a summary of [reference]?
P.S. this new topic is not the core topic of my thesis
Just open with:

This section summarises research by A et al. [1].
