added more resources to README, so this repo can serve as my full-on learning path and reinforcement learning... package? added some more chapters, removed ch3 entirely.

 The chapter numbers on the markdown files are somewhat approximate. The "fractional" chapter numbers are meant to indicate that the material is somewhere between the Rust Book chapters and may not at all emanate from that book.
 
 I should probably just put these on Exercism and delete the repo, but :man_shrugging:

+# Additional Resources
+
+Here are some other resources that could probably help reinforce the learnings here, and which in all likelihood will become fodder for some of the koans. They're in approximate order of difficulty, and some are pretty domain-specific:
+
+- [Tour of Rust](https://tourofrust.com/38_en.html) - this is wonderful, covers the same topics as the Book, but with more emphasis on what's happening under the hood memory-wise. Also has a REPL/playground thing!
+- [Rust Koans](https://github.com/crazymykl/rust-koans) - hey, someone already had this idea! 😃
+- [Rust Web Development](https://www.manning.com/books/rust-web-development) - by Bastian, looks cool and accessible
+- [Advanced Rust Web Learning Journey](https://rustwebdevelopment.com/blog/journey/) - seems like a nice, hardcore learning path once you've got the basics down. By the author of the Manning book below, Bastian Gruber.
+- [Rust and Web Assembly](https://rustwasm.github.io/docs/book/introduction.html) - Rust and Web Assembly!
