+## Prerequisites
+* Ubuntu Server with Nginx and Docker
+---
+
+## Creating repository
+
+Repository database is managed via `repo-add` script bundled with Arch Linux `pacman` package manager. Since pacman is not available in Ubuntu repository I use docker `archlinux` image for managing repository. This guide assumes that repository located in `/srv/arch-repo`. First of all move all your packages into /srv/arch-repo. Following command will create or update repository database.
+
+```sh
+REPO_URL=repo.sun.hexor.ru
+REPO_PATH=/srv/arch-repo
+docker run -v ${REPO_PATH}:/repo --rm archlinux \
+bash -c "repo-add /repo/${REPO_URL}.db.tar.gz /repo/*pkg.tar.zst"
+```
+
+### **Important aspect**
+* Name of the database should be REPO_URL.db.tar.gz, in this case REPO_URL is repo.sun.hexor.ru.
+---
+
+## Periodically database repo update
+
+I use systemd:
+```ini
+# Service unit
+# /etc/systemd/system/update-arch-repo.service
+[Unit]
+Description=Updating arch linux repository database for %I
+Requires=docker.service
+
+[Service]
+ExecStart=/usr/bin/docker run -v /srv/arch-repo:/repo --rm archlinux bash -c "repo-add /repo/%i.db.tar.gz /repo/*pkg.tar.zst"
+
+[Install]
+WantedBy=multi-user.target
+```
+
+```ini
+# Timer unit
+# /etc/systemd/system/update-arch-repo.timer
+[Unit]
+Description=Schedule arch repo database update for %I
+
+[Timer]
+# every 15 minutes
+OnCalendar=*:0/15
+
+[Install]
+WantedBy=timers.target
+```
+
+Activate timer:
+```sh
+REPO_URL=repo.sun.hexor.ru
+systemctl enable update-arch-repo@${REPO_URL}.timer
+```
+
+## Reverse proxy for HTTPS access
+
+I use NGINX
+```js
+server {
+    server_name repo.sun.hexor.ru;
+    listen [::]:443 ssl;
+    listen 443 ssl;
+    include security.conf; # my security options
+    include letsencrypt.conf; # my ssl config. 
+    root /srv/arch-repo;
+    location / {
+        autoindex on;
+        try_files $uri $uri/ =404;
+    }
+    access_log /var/log/nginx/logs/repo.sun.hexor.ru.access.log custom;
+    error_log /var/log/nginx/logs/repo.sun.hexor.ru.error.log;
+}
+```
+
+## Configure repo on your machines
+
+Add your repo to `/etc/pacman.conf`:
+
+```ini
+[repo.sun.hexor.ru]
+Server = https://repo.sun.hexor.ru
+```
