+## Setting up a Coder deployment
+
+For day-zero Coder users, we recommend following this guide to set up a local
+Coder deployment from our
+[open source repository](https://github.com/coder/coder).
+
+We'll use [Docker](https://docs.docker.com/engine) to manage the compute for a
+slim deployment to experiment with [workspaces](../user-guides/index.md) and
+[templates](../admin/templates/index.md).
+
+Docker is not necessary for every Coder deployment and is only used here for
+simplicity.
+
+### Install Coder daemon
+
+First, install [Docker](https://docs.docker.com/engine/install/) locally.
+
+> If you already have the Coder binary installed, restart it after installing
+> Docker.
+
+<div class="tabs">
+
+## Linux/macOS
+
+Our install script is the fastest way to install Coder on Linux/macOS:
+
+```sh
+curl -L https://coder.com/install.sh | sh
+```
+
+## Windows
+
+> **Important:** If you plan to use the built-in PostgreSQL database, you will
+> need to ensure that the
+> [Visual C++ Runtime](https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist#latest-microsoft-visual-c-redistributable-version)
+> is installed.
+
+You can use the
+[`winget`](https://learn.microsoft.com/en-us/windows/package-manager/winget/#use-winget)
+package manager to install Coder:
+
+```powershell
+winget install Coder.Coder
+```
+
+</div>
+
+### Start the server
+
+To start or restart the Coder deployment, use the following command:
+
+```shell
+coder server
+```
+
+The output will provide you with an access URL to create your first
+administrator account.
+
+![Coder login screen](../images/start/setup-page.png)
+
+Once you've signed in, you'll be brought to an empty workspaces page, which
+we'll soon populate with your first development environments.
+
+### Next steps

+TODO: Add link to next page.
