+# Build the project using `nix-shell`
+A `shell.nix` file is included in the repository to set up the development environment on systems that have the [Nix package manager](https://nixos.org/) installed.
+It prevents your system from getting polluted with build dependencies while also guaranteeing a reproducible build environment.
+All dependencies and tools required to build InfiniTime will automatically be fetched for you.
+
+## Install Nix
+
+Nix is available for Linux, MacOS and WSL2.
+[Visit the official website for instructions on how to install it.](https://nixos.org/download#download-nix)
+
+## Clone the repository
+
+Before building, local repository must be fully initialized.
+
+```sh
+git clone https://github.com/InfiniTimeOrg/InfiniTime.git
+cd InfiniTime
+git submodule update --init
+```
+
+## Enter the development shell
+
+Creating and entering the development environment is as easy as typing the following command in the project root:
+```sh
+nix-shell --run "$SHELL"
+```
+
+## Build the project
+Two steps are required to build the project: `cmake` and `make`.
+The `shell.nix` file provides a custom script called `cmake_infinitime` that calls `cmake` with the proper paths for the compiler and the SDK.
+
+Inside the shell you can build a target like this:
+```sh
+cmake_infinitime
+make pinetime-app
+```
+
+You can pass additional arguments to the `cmake` script:
+```sh
+cmake_infinitime -DBUILD_RESOURCES=1`
+```
+
+To make use of all the cores your host machine has pass the `-j` argument to `make`:
+```sh
+make -j$(nproc) pinetime-app
+```
+
+There are more targets and configuration options available.
+You can find them in [`buildAndProgram.md`](./buildAndProgram.md).
