There are videos on youtube that sum up main progression from stone to steel.

There are also other topics to learn, like leather making (for backpacks), animals handling, bee keeping (if you want lanterns), windmill building (to automate iron processing and as prerequisite for steel), and many more.

Survival hanbook (H key by default have a lot of info and guides on game mechanics). Otherwise, google videos on certain topics.

It is fun to pass all these milestones and see how your small village grows.
