+
+## Overview
+This Stack provides a Docker Swarm-based installation of Code Server, a lightweight, self-hosted version control server for Git repositories.
+
+---
+
+## Architecture
+| Service | Image | Port | Role |
+|---------|-------|------|------|
+- **Host:** docker4
+- **Network:** netgrimoire
+- **Exposed via:** code.netgrimoire.com, Internal only
+- **Homepage group:** Development
+
+---
+### Build & Configuration
+
+#### Prerequisites
+No specific prerequisites for this stack.
+
+#### Volume Setup
+```bash
+mkdir -p /DockerVol/code/config
+chown -R code:code /DockerVol/code/
+```
+
+#### Environment Variables
+```bash
+# generate: openssl rand -hex 32
+PUID=1964
+PGID=1964
+SUDO_PASSWORD=F@lcon13
+PROXY_DOMAIN=code.netgrimoire.com
+TZ=America/Chicago
+```
+
+#### Deploy
+```bash
+cd services/swarm/stack/vscode
+set -a && source .env && set +a
+docker stack config --compose-file vscode-stack.yml > resolved.yml
+docker stack deploy --compose-file resolved.yml vscode
+rm resolved.yml
+docker stack services vscode
+```
+
+#### First Run
+This process is automatically handled by the Docker Swarm deployment.
+
+---
+### User Guide
+
+#### Accessing vscode
+| Service | URL | Purpose |
+- **Host:** code.netgrimoire.com:8443
+- Internal only
+
+#### Primary Use Cases
+To access and contribute to your Git repositories, simply navigate to the Code Server interface via the provided URL. For detailed instructions, refer to the official [Code Server documentation](https://code-server.org/).
+
+#### NetGrimoire Integrations
+This Stack integrates with other services in NetGrimoire through environment variables and labels:
+- Caddy reverse proxy: caddy-docker-proxy:code.netgrimoire.com
+- Kuma monitoring: kuma.cs.http.name:Code Server, kuma.cs.http.url:http://code-server:8443
+- Diun image update monitoring: enabled
+
+---
+### Operations
+
+#### Monitoring
+```bash
+docker stack services vscode
+docker service logs vscode -f
+```
+
+#### Backups
+Critical vs. reconstructable paths:
+- Critical: /DockerVol/code/data
+- Reconstructable: /DockerVol/code/config
+
+#### Restore
+```bash
+cd services/swarm/stack/vscode
+./deploy.sh
+```
+
+---
+### Common Failures
+
+| Symptom | Cause | Fix |
+|---------|-------|-----|
+| Code Server does not start on docker4 | Incorrect PUID/PGID or SUDO_PASSWORD | Verify that these environment variables are set correctly in .env. |
+| Connection issues with caddy reverse proxy | Invalid CADDY_PORT or proxy configuration in .env | Check the CADDY_PORT value and ensure that the `caddy` labels match the service name. |
+| Kuma monitoring is not receiving updates | Missing `kuma.*` labels in service definition or incorrect logging levels | Ensure all required `kuma.*` labels are included in the service definition and adjust logging levels as needed. |
