If Ethereum is the future what we believe in, then a logical question is: When? How? But most import is what can I do? The answer is by contributing to open source.

Even though there is an open opportunity. We need to follow the etiquette to start contributing. There is a lay of the land you can discover. Imagine an onion with its layers, not necessarily in perfect order. You can peel it, by a simple action. I loved what Danny Ryan suggested at Devcon IV:

Research sounds like a daunting word. You might think am I able to propose new topics? At first, definitely you won't. But the best way to learn something is by carefully reading.

Read drafts, to understand the initial ideas. Read to fix typos and find bugs. Read and improve the figures. Start reading something you find interesting at ethresear.ch.

So to start contributing to Ethereum and Open-Source, just read and find ways to improve what stumbles on your screen.
