+# Setup
+
+## Postman
+
+To make API calls, you will need to install a tool like [Postman](https://www.postman.com/downloads/).
+
+> 💡 You can also use [Hoppscotch](https://hoppscotch.io/), [curl](https://curl.haxx.se/) (often already installed on your computer), or whatever other tool you want for your tests since they will be personal, but we highly recommend `postman` as we will explain you how to use it.
+
+## Forge
+
+Please follow the instructions given [here](https://book.getfoundry.sh/getting-started/installation).
+
+After the installation, run the following command to ensure it has been properly installed on your computer:
+
+```shell
+forge --version
+```
+
+It should print your current version.
+
+## Initialize your project
+
+Now we will initialize the project:
+
+```shell
+forge init Roshambo
+```
+
+> For those wondering, Roshambo is simply another name for the classic game Rock, Paper, Scissors.
