Introduction to Filecoin app building

Slides from intro presentation: https://speakerdeck.com/andrewxhill/intro-to-filecoin-building-apps-with-powergate

In this workshop, we are going to introduce you to Filecoin through the use of the Powergate. While you can develop using Lotus or other Filecoin implementations directly, the Powergate is designed to provide the necessary abstractions to build Filecoin storage into your application. Some features of the Powergate include fast data retrieval with IPFS serving as a caching layer, deal management, multi-tenant wallet APIs, and more. The system comes set up to run locally in Docker or deploy to your servers.

We'll cover the Powergate CLI and the Powergate JavaScript Client in the two parts of the workshop. To prepare, we encourage you to install a few things before we get started.

On chatting to people

Chat is not the same as conversation. When you tag someone using the "@" or if you send them a direct message, you may be directly forcing them to change their focus to your problem. While this is good for you, it can be bad for a healthy and productive community. Here are a couple of rules to abide.

Only "@" tag people's names in the following cases.
- Your comment is urgent/time-sensitive and you need the help of the "@" target. What is urgent? You are running a production application with 100s of users facing a broken API, it's urgent. You are experimenting or taking part in a competition and want an answer quickly, it's not urgent.
- Your comment has grown stale and you still need an answer that the "@" target can provide. What is stale? In most cases, more than 2 days seems reasonable or if it's a weekend, 3 or more.
- You comment is in a channel or thread where the "@" target is not present but you need them aware.
Abide by the "no hello" rule at all times. Provide
