general: Add detailed README.md

Previously the README.md was sparse, including no intructions on setting
up PixelFed. This could be progibitive for attracting new contributors.
I have updated the README and based the install instructions on
https://gist.github.com/dansup/999de4577f864d1822d226b9ddd62ca0.

Closes https://github.com/dansup/pixelfed/issues/18

+# PixelFed: Federated Image Sharing
 
-> This project is still in active development and not yet ready for use.
+PixelFed is a federated social image sharing platform, similar to instagram.
+Federation is done using the [ActivityPub](https://activitypub.rocks/) protocol,
+which is used by [Mastodon](http://joinmastodon.org/), [PeerTube](https://joinpeertube.org/en/),
+[Pleroma](https://pleroma.social/), and more. Through ActivityPub PixelFed can share
+and interact with these platforms, as well as other instances of PixelFed. 
+
+**_Please note this is alpha software, not recommended for production use,
+and federation is not supported yet._**
+
+PixelFed is very early into the development stage. If you would like to have a
+permanent instance with minimal breakage, **do not use this software until
+there is a stable release**. The following setup instructions are intended for
+testing and development.
+
+## Requirements
+ - PHP >= 7.1.3 (7.2+ recommended for stable version)
+ - MySQL, Postgres (MariaDB and sqlite are not supported yet)
+ - Redis
+ - Composer
+ - GD or ImageMagick
+ - OpenSSL PHP Extension
+ - PDO PHP Extension
+ - Mbstring PHP Extension
+ - Tokenizer PHP Extension
+ - XML PHP Extension
