+# Getting started with development
+
+!!! info
+
+    This guide will take you through the process of getting the [`pems`](https://github.com/compilerla/pems) project running in
+    your local development environment.
+
+## Prerequisites
+
+This section describes the tooling you need to have installed and configured on your development machine before continuing.
+
+### Git
+
+Git is an open source version control system that we use in `pems` to track changes to the codebase over time. Many operating
+systems come with Git already installed. Check if you have Git installed in a terminal with the following command:
+
+```shell
+git --version
+```
+
+If git is installed, the output should look similar to:
+
+```console
+$ git --version
+git version 2.39.5
+```
+
+If Git is not installed, head to the [Git downloads page](https://git-scm.com/downloads) to get an installer for your operating
+system.
+
+### Docker and Docker Compose
+
+Docker and Docker Compose (or just Compose) are key tools that allow for running the various services required for `pems`.
+
+Confirm if you already have Docker installed, in a terminal:
+
+```shell
+docker --version
+```
+
+If Docker is installed, the output should look similar to:
+
+```console
+$ docker --version
+Docker version 27.4.0, build bde2b89
+```
+
+And similarly to check if Compose is installed:
+
+```shell
+docker compose version
+```
+
+When Compose is installed, output will look similar to:
+
+```console
+$ docker compose version
+Docker Compose version v2.31.0
+```
+
+There are different ways to acquire this software depending on your operating system. The simplest approach for Windows and
+MacOS users is to install [Docker Desktop](https://docs.docker.com/desktop/).
+
+??? warning "License requirements for Docker Desktop"
+
+    Use of Docker Desktop is subject to [Docker's licensing terms](https://www.docker.com/legal/docker-subscription-service-agreement/).
+    In particular, note that **Section 4.2** calls out government users specifically:
+
+    > Government Entities shall not use Docker Desktop or access other Entitlements of the Service without purchasing a Subscription.
+
+#### Windows
+
+It is possible to run Docker and Compose on Windows without installing Docker Desktop. This involves using the [Windows Subsystem
+for Linux v2 (WSL2)](https://learn.microsoft.com/en-us/windows/wsl/install#step-2-update-to-wsl-2), where Docker is configured
+to run.
+
+This article walks through this procedure in more detail:
+[_How to run docker on Windows without Docker Desktop_](https://dev.to/_nicolas_louis_/how-to-run-docker-on-windows-without-docker-desktop-hik).
+
+#### MacOS
+
+With MacOS and [Homebrew](https://brew.sh/), installing Docker and Compose are as simple as:
+
+```shell
+brew install docker docker-compose colima
+```
+
+Once the install completes, start `colima` (an [open source container runtime](https://github.com/abiosoft/colima)):
+
+```shell
+brew services start colima
+```
+
+#### Linux
+
+Docker CE (also known as Docker Engine) is how to run Docker and Compose on Linux. Docker provides an
+[installation guide for Docker CE](https://docs.docker.com/engine/install/).
+
+### VS Code and Dev Containers extension
+
+VS Code is an open source Integrated Development Environment (IDE) from Microsoft. Check if you already have it installed:
+
+```shell
+code -v
+```
+
+If installed, output should look similar to:
+
+```console
+$ code -v
+1.95.3
+f1a4fb101478ce6ec82fe9627c43efbf9e98c813
+x64
+```
+
+Otherwise, [download VS Code](https://code.visualstudio.com/download) for your operating system.
+
+Once installed, open VS Code and enter `Ctrl`/`Cmd` + `P` to open the VS Code Quick Open pane. Then enter:
+
+```console
+ext install ms-vscode-remote.remote-containers
+```
+
+`ms-vscode-remote.remote-containers` is the Extension ID of the
+[Dev Containers extension from Microsoft](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers).
+
+For more about why we use Dev Containers, check our Compiler's blog post:
+[_How to support a platform-agnostic engineering team with VS Code Dev Containers_](https://compiler.la/blog/2024/devcontainer-platform-agnostic-team).
