+# 🚀 Installation Guide
+
+This guide will help you install Fennix on your system.
+
+## 🛠️ Preparing the Environment
+
+There are two ways to build the project:
+
+1.  **🐳 Use Dev Container (Recommended)**
+    * This is the easiest way to prepare the environment for building the project. But firstly, you need to install [Docker](https://docs.docker.com/get-docker/) and [Visual Studio Code](https://code.visualstudio.com/).
+    * After installing Docker and Visual Studio Code, you can open the project in Visual Studio Code and click on the "Reopen in Container" button.
+    * This will open the project in a Dev Container with all the required tools installed.
+    * If you encounter errors while the Dev Container is building, ensure the following are correctly configured:
+        * `/tmp/.X11-unix`
+        * Environment variable `XAUTHORITY`
+        * `/run/user/1000/pulse/native`
+        * **Note:** These configurations are only necessary if you plan to use QEMU inside the container.
+2.  **💻 Build the Project Locally**
+    * The instructions below will guide you through the process of building the project locally.
+
+**NOTE:** You MUST have `autoconf 2.69` and `automake 1.15.1` versions installed on your system. A complete list of dependencies can be found in the [.devcontainer/Dockerfile](.devcontainer/Dockerfile) file.
+
+Before building the project, you need to build the cross-compiler toolchain and QEMU.  
+You can do this by running the following command:
+
+```sh
+make setup
+```
+
+This will clone, patch, and build the required tools for you.
+
+Alternatively, if you wish to skip building QEMU, you can run `make setup-no-qemu`.  
+However, in this case, you will need to manually specify the path to the QEMU binary in the `config.mk` file.
+
+## 🏗️ Building the Project
+
+To build the project, run:
+
+```sh
+make build
+```
+
+This will build the kernel, userspace, and drivers. The resulting ISO image will be `Fennix.iso`.
+
+## 🚀 Running the OS
+
+To run the OS, execute:
+
+```sh
+make run
+```
+
+The `run` target will automatically build the project if it hasn't been built yet.
+
+## ⚙️ Additional Configuration
+
+You can customize the project by editing the `config.mk` file.
+
+## 🧪 Debugging
+
+If you use Visual Studio Code, you can press `F5` to start debugging the OS.  
+The configuration is already set up for you.
+
+Alternatively, you can run the following command to start debugging:
+
+```sh
+make debug
+```
+
+This will start QEMU in debug mode, allowing you to connect to it using GDB.
+
+The GDB FIFO file is located at `/tmp/gdb-fennix`.
