I have not yet added info about some new features but updated existing stuff to the latest version.

I plan to extend it soon. One particular thing I want to add is factory pattern.

• [x] I solemnly swear that this is all original content of which I am the original author
• [x] Pull request title is prepended with [language/lang-code] (example [python/fr-fr] or [java/en])
• [x] Pull request touches only one file (or a set of logically related files with similar changes made)
• [x] Content changes are aimed at intermediate to experienced programmers (this is a poor format for explaining fundamental programming concepts)
• [x] If you've changed any part of the YAML Frontmatter, make sure it is formatted according to CONTRIBUTING.md
  • [x] Yes, I have double-checked quotes and field names!

I set it to don't merge / WIP so that you can keep working on it and then we merge it when it's done. What do you think?

Okay, no problem, I hope to get back to it soon.
