+## The Game of Go
+Go is a 2 player abstract strategy game of perfect information.
+
+Players take turns placing playing pieces called stones on the intersections of a gridded board. This board is usually a square 19 points across. Stones remain on the points at which they are placed unless they are captured by the opposing player. Capture occurs when a stone or group of stones no longer has any adjascent empty points.
+
+Play ends when both players agree that they have exhausted all advantageous moves. Scoring is determined by counting and comparing the area controlled by either player.
+
+For a more detailed explanation of the rules, please see [my previous illustrated explanation of the game of go](https://github.com/sorrelbri/browser-go-proto#the-game-of-go) or the [American Go Association's Concise Rules of Go.](https://www.usgo.org/aga-concise-rules-go)

+## Technical Challenges
+### Modeling Game State
+A go board typically consists of 361 points which can exist in a number of states.
+
+### Partitioning Game Rooms
+Finding a game starts with joining a game room.

+Watch an in progress game, join a game, or study a historic game.
