+# Guessing Game
+
+First _project_ in the Rust Book. Goal is to make a simple rust script that generates a random number and asks the user to guess it.
+
+### Dependencies
+
+```
+rand=0.8.5
+```
+
+View [Rust Poker](https://git.adityagupta.dev/sortedcord/rust-poker) to see an extended use case of Rust's RNG capabilities.
