docs: Create dedicated CONTRIBUTING.md

Create a dedicated file for explaining how to install
and test the project. (I had forgotten a few steps, so recording
what I re-learned to save myself and others time in the future).

+## Environment Setup
+
+**Install Java**
+
+For these instructions we'll use SDKman! to manage the installation
+
+```bash
+sudo apt install zip unzip
+curl -s "https://get.sdkman.io" | bash
+```
+
+Install Java 11
+
+```bash
+sdk install 11.0.25-tem
+```
+
+Check installation
+```
+java -version
+```
+
+## Build
+TNoodle CLI uses Gradle, so building from source is just the standard gradle build command.
+```
+./gradlew build
+```
+The built .jar file will be located at `./build/releases/tnoodle-cli-VERSION.jar` 
+
+If you want to build the full distributions for each operating system, then use the `runtimeZip` task.
+```
+./gradlew runtimeZip
+```
+The built distributions will be in `./build/releases/`
