+
+HedgeDoc is an open-source collaborative Markdown editor. Think *Google Docs for Markdown*: multiple people can edit the same note in real-time, with support for diagrams, math, polls, and slide decks. In this post we’ll walk through setting up your own instance on a server, secured with HTTPS.
+
+---
+
+## Prerequisites
+
+- A Linux server with **Docker** and **Docker Compose**
+- A domain name pointing to your server (e.g. `notes.alipourimjourneys.ir`)
+- **Nginx** installed for reverse proxying
+- **Certbot** for Let’s Encrypt certificates
+
+---
+
+## 1. Create the project directory
+
+{{< highlight bash >}}
+mkdir ~/hedgedoc && cd ~/hedgedoc
+{{< /highlight >}}
+
+---
+
+## 2. Create `.env`
+
+{{< highlight env >}}
+POSTGRES_PASSWORD=ChangeThisStrongPassword
+HD_DOMAIN=notes.alipourimjourneys.ir
+{{< /highlight >}}
+
+Generate a strong password with:
+
+{{< highlight bash >}}
+openssl rand -base64 32
+{{< /highlight >}}
+
+---
+
+## 3. Create `docker-compose.yml`
+
+{{< highlight yaml >}}
+version: "3.9"
+
+services:
+  db:
+    image: postgres:16
+    environment:
+      POSTGRES_USER: hedgedoc
+      POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
+      POSTGRES_DB: hedgedoc
+    volumes:
+      - db:/var/lib/postgresql/data
+    restart: unless-stopped
+
+  hedgedoc:
+    image: quay.io/hedgedoc/hedgedoc:1.10.2
+    depends_on:
+      - db
+    environment:
+      CMD_DB_URL: postgres://hedgedoc:${POSTGRES_PASSWORD}@db:5432/hedgedoc
+      CMD_DOMAIN: ${HD_DOMAIN}
+      CMD_PROTOCOL_USESSL: "true"
+      CMD_URL_ADDPORT: "false"
+      CMD_PORT: "3000"
+      CMD_EMAIL: "true"
+      CMD_ALLOW_EMAIL_REGISTER: "false"
+    volumes:
+      - uploads:/hedgedoc/public/uploads
+    ports:
+      - "127.0.0.1:3000:3000"
+    restart: unless-stopped
+
+volumes:
+  db:
+  uploads:
+{{< /highlight >}}
+
+Bring it up:
+
+{{< highlight bash >}}
+docker compose up -d
+{{< /highlight >}}
+
+---
+
+## 4. Get a Let’s Encrypt certificate
+
+Request a cert with a **DNS challenge**:
+
+{{< highlight bash >}}
+sudo certbot certonly   --manual   --preferred-challenges dns   -d notes.alipourimjourneys.ir   -m you@example.com   --agree-tos --no-eff-email
+{{< /highlight >}}
+
+Add the TXT record certbot asks for, wait for DNS to propagate, then continue.  
+Certificates will be in:
+
+{{< highlight bash >}}
+/etc/letsencrypt/live/notes.alipourimjourneys.ir/
+{{< /highlight >}}
+
+---
+
+## 5. Configure Nginx
+
+Create `/etc/nginx/sites-available/notes.alipourimjourneys.ir`:
+
+{{< highlight nginx >}}
+server {
+  server_name notes.alipourimjourneys.ir;
+
+  listen 80;
+  listen [::]:80;
+  return 301 https://$host$request_uri;
+}
+
+server {
+  server_name notes.alipourimjourneys.ir;
+
+  listen 443 ssl http2;
+  listen [::]:443 ssl http2;
+
+  ssl_certificate     /etc/letsencrypt/live/notes.alipourimjourneys.ir/fullchain.pem;
+  ssl_certificate_key /etc/letsencrypt/live/notes.alipourimjourneys.ir/privkey.pem;
+
+  location / {
+    proxy_pass http://127.0.0.1:3000;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto https;
+
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection "upgrade";
+  }
+}
+{{< /highlight >}}
+
+Enable the config and reload Nginx:
+
+{{< highlight bash >}}
+sudo ln -s /etc/nginx/sites-available/notes.alipourimjourneys.ir /etc/nginx/sites-enabled/
+sudo nginx -t && sudo systemctl reload nginx
+{{< /highlight >}}
+
+---
+
+## 6. Create users
+
+Because we disabled self-registration, create accounts manually:
+
+{{< highlight bash >}}
+docker compose exec hedgedoc ./bin/manage_users --add alice@example.com
+{{< /highlight >}}
+
+You’ll be prompted for a password.  
+To reset a password later:
+
+{{< highlight bash >}}
+docker compose exec hedgedoc ./bin/manage_users --reset alice@example.com
+{{< /highlight >}}
+
+---
+
+## 7. Done!
+
+Visit [https://notes.alipourimjourneys.ir](https://notes.alipourimjourneys.ir) and log in with the user you created. You now have your own collaborative Markdown editor 🎉
+
+---
+
+**Extras:**
+
+- Backups: dump the PostgreSQL database and save the `uploads` volume.  
+- Upgrades: `docker pull quay.io/hedgedoc/hedgedoc:latest && docker compose up -d`.  
+- Integrations: HedgeDoc supports S3/MinIO image storage, GitHub/GitLab/Google login, and more.
