You might want to check out Eric Flint’s 1632 series. A small Virginia mining town is sent back in time and translocated to 1631 Germany, the series goes into how they try to build up a more technologically advanced civilization. S. M. Stirling‘s Nantucket series is somewhat similar. Nantucket is sent back in time to 1250 BC and they try to build a society there. David Weber’s Safehold series has a different premise, it’s set in the far future on a planet with medieval level technology. A lot of it is about the protagonists trying to build up their tech level.
