refactor: rewrite docmost_dev to match template conventions

- Rename docker-compose.yml to compose.yaml
- Add env var defaults for all images, ports, and secrets
- Convert env style from YAML mapping to list style
- Use VOL_PATH base /data pattern for all volumes
- Add proxy network for docmost, internal network for db/redis
- Add missing sample.env with all configurable vars
- Rewrite README with new section order and multi-service docs

 # Docmost
 
-ENV: https://docmost.com/docs/self-hosting/environment-variables
+## Overview
 
-Redis: https://hub.docker.com/_/redis
+Docmost is a collaborative wiki and documentation platform, similar to Notion or Outline. It supports real-time editing, page hierarchies, and rich content. This stack includes PostgreSQL for data storage and Redis for session management and caching.

+- **Reverse Proxy Port:** `3000` (internally), mapped to `8000` by default
+
+## Getting Started
+
+Open http://localhost:8000 in your browser:
+
+1. Create your admin account on first visit
+2. Start creating pages and organizing your workspace
+3. Optionally configure SMTP in the compose environment for email invites
+
+## Environment Variable Notes
+
+| Variable | Description |
+|---|---|
+| `DOCMOST_IMAGE` | Docmost container image (default: `docmost/docmost:latest`) |
+| `POSTGRES_IMAGE` | PostgreSQL image (default: `postgres:16-alpine`) |
+| `REDIS_IMAGE` | Redis image (default: `redis:7-alpine`) |
+| `DOCMOST_RESTART` | Restart policy for all services (default: `unless-stopped`) |
+| `DOCMOST_PORT` | Published port for the web UI (default: `8000`) |
+| `VOL_PATH` | Base path for persistent data volumes (default: `/data`) |
+| `APP_URL` | Public-facing URL of your Docmost instance |
+| `APP_SECRET` | Secret key used for encryption and sessions — generate a long random string |
+| `DB_PASSWORD` | Password for the PostgreSQL database user |
+
+## Volume Notes
+
+| Volume | Purpose |
+|---|---|
+| `${VOL_PATH:-/data}/docmost/storage` | Docmost uploads and data storage |
+| `${VOL_PATH:-/data}/docmost/db` | PostgreSQL database files |
+| `${VOL_PATH:-/data}/docmost/redis` | Redis persistence data |
+
+## Network Notes
+
+- `proxy` — external network for reverse proxy access to the Docmost web UI
+- `docmost_internal` — internal bridge network for communication between Docmost, PostgreSQL, and Redis
+
+Create the proxy network once with:
+
+```bash
+docker network create proxy
+```
+
+## Docker Run
+
+This is a multi-service stack — use `docker compose` instead of individual `docker run` commands.
+
+## Dockhand Stack, Deploy from Git
+
+- **Cookbooks Repository**
+- **stackname:** docmost_dev
+- **Compose file path:** docmost_dev/compose.yaml
+- **Additional env file (optional):** docmost_dev/sample.env
+
+Load `docmost_dev/sample.env` into the Environment variables in Dockhand, then create the Stack.
