+# Whiley Explorations
+
+You have a couple options to explore Whiley:
+
+<details><summary><b>Install the Whiley Compiler</b></summary>
+
+To install Whiley, you will need to already have installed Java before installing. In addition, you may also need to have Cargo (from Rust) installed as well to install Whiley.
+
+After getting both of these dependencies stated, type in the following command:
+
+```
+cargo install whiley
+```
+
+Afterwards, you can start running scripts. Though a bit cumbersome, to run an example code, copy the code from the scripts folder and paste it into `main.whiley`. Another way is to duplicate one of the files from scripts folder to the src folder and then rename it to `main.whiley` (if you run into issues, delete the existing file first). Then finally, at the root folder (`ple/whiley`), perform the following commands:
+
+```
+wy build
+wy run
+```
+
+</details>
