 No database. No image compression. No time limits. No additional dependencies.
 
 Features:
+
 * Upload images via Drag&Drop
 * Easy copy share link
 * MIME type detecting
 
 See deployment options in Bottle documentation: https://bottlepy.org/docs/dev/deployment.html
+
+# Run imgs in Docker
+
+Clone repository and edit **imgs.ini**.
+
+Build Docker image:
+
+```shell
+docker build --tag imgs .
+```
+
+Run container from image. Replace **/path/to/your/uploads/dir** with path to directory where you want to store images:
+
+```shell
+docker run -d \
+    --name imgs \
+    --publish 127.0.0.1:5000:5000 \
+    --volume /path/to/your/uploads/dir:/opt/imgs/uploads \
+    imgs
+```
+
+imgs will launched on `127.0.0.1:5000`. Set up reverse proxy server. I recommed to use basic authentication to prevent abuses. Nginx virtual host example:
+
+```nginx
+server {
+    listen 80;
+    server_name yourdomain.tld;
+    root /path/to/imgs/root;
+
+    location / {
+        auth_basic "Authentication required";
+        auth_basic_user_file /path/to/.htpasswd;
+        proxy_pass http://127.0.0.1:5000;
+    }
+
+    location ~* ^/favicon.ico$ {
+        try_files $uri $uri/ =404;
+    }
+
+    location ~* \..* {
+        auth_basic off;
+        proxy_pass http://127.0.0.1:5000;
+    }
+}
+```
+
+# Additional
+
+## imgs client with CLI
+
+imgs has a simple CLI tool based on curl. Copy **imgs** script to your PATH.
+
+```shell
+sudo cp imgs /usr/bin/imgs
+```
+
+## Nautilus integration
+
+Push files to your imgs instance via GNOME Files (former name: Nautilus). Depends on: curl, libnotify (notify-send utility).
+
+Just place **Upload to imgs** script into **~/.local/share/nautilus/scripts/** directory.
+
+```shell
+DIR=~/.local/share/nautilus/scripts/; mkdir -p $DIR && cp Upload\ to\ imgs $DIR
+```
