+## Foreword
+
+This guide assumes that:
+
+- Shaarli runs in a Docker container
+- The host's `10080` port is mapped to the container's `80` port
+- Shaarli's Fully Qualified Domain Name (FQDN) is `shaarli.domain.tld`
+- HTTP traffic is redirected to HTTPS
+
+## Apache
+
+- [Apache 2.4 documentation](https://httpd.apache.org/docs/2.4/)
+    - [mod_proxy](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html)
+    - [Reverse Proxy Request Headers](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#x-headers)
+
+The following HTTP headers are set by using the `ProxyPass` directive:
+
+- `X-Forwarded-For`
+- `X-Forwarded-Host`
+- `X-Forwarded-Server`
+
+```apache
+<VirtualHost *:80>
+    ServerName shaarli.domain.tld
+    Redirect permanent / https://shaarli.domain.tld
+</VirtualHost>
+
+<VirtualHost *:443>
+    ServerName shaarli.domain.tld
+
+    SSLEngine on
+    SSLCertificateFile    /path/to/cert
+    SSLCertificateKeyFile /path/to/certkey
+
+    LogLevel warn
+    ErrorLog  /var/log/apache2/shaarli-error.log
+    CustomLog /var/log/apache2/shaarli-access.log combined
+
+    RequestHeader set X-Forwarded-Proto "https"
+
+    ProxyPass        / http://127.0.0.1:10080/
+    ProxyPassReverse / http://127.0.0.1:10080/
+</VirtualHost>
+```
