- pgSchema "mesh" with 4 tables isolating the peer mesh domain
- Enums: visibility, transport, tier, role

+# Development
+
+## Prerequisites
+
+To get started with TurboStarter, ensure you have the following installed and set up:
+
+* [Node.js](https://nodejs.org/en) (22.x or higher)
+* [Docker](https://www.docker.com) (only if you want to use local services e.g. database)
+* [pnpm](https://pnpm.io)
+
+## Project development
+
+<Steps>
+  <Step>
+    ### Install dependencies
+
+    Install the project dependencies by running the following command:
+
+    ```bash
+    pnpm i
+    ```
+
+    <Callout title="Why pnpm?">
+      It is a fast, disk space efficient package manager that uses hard links and symlinks to save one version of a module only ever once on a disk. It also has a great [monorepo support](https://pnpm.io/workspaces). Of course, you can change it to use [Bun](https://bunpkg.com), [yarn](https://yarnpkg.com) or [npm](https://www.npmjs.com) with minimal effort.
+    </Callout>
+  </Step>
+
+  <Step>
+    ### Setup environment variables
+
+    Create a `.env.local` files from `.env.example` files and fill in the required environment variables.
+
+    You can use the following command to recursively copy the `.env.example` files to the `.env.local` files:
+
+    <Tabs items={["Unix (MacOS/Linux)", "Windows"]}>
+      <Tab value="Unix (MacOS/Linux)">
+        ```bash
+        find . -name ".env.example" -exec sh -c 'cp "$1" "${1%.example}.local"' _ {} \;
+        ```
+      </Tab>
+
+      <Tab value="Windows">
+        ```bash
+        Get-ChildItem -Recurse -Filter ".env.example" | ForEach-Object {
+            Copy-Item $_.FullName ($\_.FullName -replace '\.example$', '.local')
+        }
+        ```
+      </Tab>
+    </Tabs>
+
+    Check [Environment variables](/docs/web/configuration/environment-variables) for more details on setting up environment variables.
+  </Step>
+
+  <Step>
+    ### Setup services
+
+    If you want to use local services like [database](/docs/web/database/overview) (**recommended for development purposes**), ensure Docker is running, then setup them with:
+
+    ```bash
+    pnpm services:setup
+    ```
+
+    This command initiates the containers and runs necessary setup steps, ensuring your services are up to date and ready to use.
+  </Step>
+
+  <Step>
+    ### Start development server
+
+    To start the application development server, run:
+
+    ```bash
+    pnpm dev
+    ```
+
+    Your app should now be up and running at [http://localhost:3000](http://localhost:3000) 🎉
+  </Step>
+
+  <Step>
+    ### Deploy to Production
+
+    When you're ready to deploy the project to production, follow the [checklist](/docs/web/deployment/checklist) to ensure everything is set up correctly.
+  </Step>
