A [question](https://nforum.ncatlab.org/discussion/2748/a-learning-roadmap-for-higher-topos-theory/) posed at the nForum asked for a roadmap to learn Lurie's Higher Topos Theory, including helpful sources other than HTT itself (to read along it) and information about which parts of HTT should be skipped ([example guide](https://ncatlab.org/spahn/show/a%20reading%20guide%20to%20HTT)).

This question asks for a similar guide for learning algebra in the context of $(\infty,1)$-categories, at the level of generality of Lurie's [Higher Algebra](http://www.math.harvard.edu/~lurie/papers/HA.pdf).

More specifically, *the focus should not be on DG-algebras*, being instead about more general mathematical objects such as $\mathbb{E}_k$-rings.

Nice things to include in such a guide would be other helpful sources, parts that should be skipped, or concepts that are best treated as black boxes (at least when first approaching it).
