+# Graph Explorer
 This is a WOK (wealth of knowledge) explorer that I made for fun and profit for CSE280.
+
+## Installation
+
+All you need is pygame!
+
+```bash
+pip install pygame
+```
+
+## Usage
+```bash
+python3 main.py
+```
+Select a node by clicking it; this will focus the links that are directed out of that node.
+
+Press "P" to select all nodes.
+
+Press "F" to find a node (this is done as a prompt in the shell).
+
+Press "Space" to pause the visualization.
+
+Press "C" to clear all the selected nodes.
+
+
+## Using the WOK Builder
+
+```bash
+python3 builder.py
+```
+
+The builder is a simple one; click anywhere where there is not a node to create a new one (prompted in terminal).
+
+You can add links between nodes by selecting first the source node and then the directed node. A description for the link will be prompted in the terminal.
+
+If you accidentally link two nodes, you can cancel the link by typing "no" in the description.
+
+Press "F" to search for a node. If found, this node will turn blue.
