+## Basic Usage
+
+#### Requirements
+- Git
+- Cargo (Rustup)
+
+##### Step 1 - Build the project
+Simply do `cargo build --release`. It might take a while.
+
+##### Step 2 - Write the Script that Igneous should follow
+
+The script format is simple. There are 3 command types:
+`S!bot? are you there?` - wait for user to type the preset string ("bot? are you there?")
+`I!yeah, I'm here` - reply with the preset string ("yeah, I'm here")
+`IMG![images/bot-selfie.png]` - reply with image
+
+All commands **must** have a timeout (the timeout **can** be `0.0`) after the command executes:
+`S!bot? are you there?+3.0` - wait 3 seconds after the user types the preset string
+
+Always start a bot with an `S!`. That would be your trigger.
+
+A simple ping-pong bot:
+```
+S!bot? are you there?+2.0
+I!yeah, I'm here+0.0
+S!ok+2.0
+I!soooooo, why did you call me?+0.0
+IMG![Confused.png]+0.0
+```
+
+Save the file.
+
+##### Step 3 - Run
+
+Use the following command to run the bot:
+
+`DISCORD_TOKEN="<your discord bot token>" ./target/release/Igneous <path to your script file>`
