Fundamentals on Solidity. Covers multiple lessons.

**We need to add some more supporting content on Solidity types, etc**

Earn some $CODE!!! We have $CODE quests for writing content on Solidity.... among others! We need some fundamentals for our lessons.

IMPORTANT. PLEASE FAMILIARISE YOURSELF WITH THIS TO SAVE TIME AND EFFORT FOR EVERYONE

See the **four Solidity side drawer elements in Lesson 1** for
**tone, style and succinctness - therefore the perfect model of what your content can look like.**
We're obviously trying to **maintain consistency**. You can see these **finished fundamentals** in here:
