+## How to Guides
+
+These are easy to follow guides to solve an specific problem you might have.
+
+### Start a new project
+
+In this guide we will create a new project and add your first solution for a [Advent of Code](https://adventofcode.com/) site.
+
+#### Initialize the project
+
+To start a new working folder for advent of code use the command [`init`](https://github.com/dolfolife/aoctl?tab=readme-ov-file#init).
+
+> By default it will create a new folder named `adventofcode` but you can change that with the parameter `--path` to initialize the project with a specific name.
+```bash
+aoctl init -p aoc-solutions
+```
+
+Next, we need to add our user session to the project by editing the `.env` file. To fetch this user session you can check the `session` cookie in the cookies section of the browser inspect console.
+
+> The session cookie is a httpOnly cookie, so it can't be fetch using `document.cookie` object
+
+To add the session to the project use the `session` cmd
+
+```bash
+aoctl session -s <SESSION>
+```
