+
+#### What is this?
+It is nginx statically linked against a custom OpenSSL build, with embedded Brotli support. Secured by default (no root processes, even the master one), it should be safe to use...
+
+#### Features
+- Based on Alpine Linux.
+- nginx built against OpenSSL.
+- OpenSSL : no weak algorithms.
+- OpenSSL : ChaCha20 ciphers support.
+- nginx : HTTP/2 (+NPN) support.
+- nginx : Brotli compression support (and configured).
+- nginx : no root master process.
+- nginx : AIO Threads support.
+- nginx : no unnessary modules.
+- nginx : optimized configuration.
+
+#### Notes
+It is required to chown your certs files with the right uid/pid and change the `listen` directive to 8000/4430 instead of 80/443. Linux 3.17+, and the latest Docker stable are recommended.
+
+#### Volumes
+- **/sites-enabled** : vhosts files (*.conf)
+- **/conf.d** : additional configuration files
+- **/certs** : SSL/TLS certificates
+- **/var/log/nginx** : nginx logs
+- **/passwds** : authentication files
+
+#### Build-time variables
+- **NGINX_VERSION** : version of nginx
+- **OPENSSL_VERSION** : version of LibreSSL
+
+#### Environment variables
+- **GID** : nginx group id *(default : 991)*
+- **UID** : nginx user id *(default : 991)*
+
+#### How to use it?
+https://github.com/hardware/mailserver/wiki/Reverse-proxy-configuration
+
+Some configuration files located in `/etc/nginx/conf` are already provided, you can use them with the `include` directive.
+
+- `ssl_params` : TLS (1.0, 1.1, 1.2), CHACHA20, AES 256/128. Nice balance between compatibility and security.
+- `headers_params` : HSTS (+ preload), XSS protection...
+- `proxy_params` : useful with `proxy_pass`.

+SSL: cast hostname in SSL_set_tlsext_host_name().
+
+BoringSSL promoted this macro to a proper function,
+so it requires parameters with correct types now.
