+Host based Access Control
+-------------------------
+
+It is possible to configure Apache2-like access control
+lists. Values are read from file `/etc/default/pmgproxy`. For example:
+
+----
+ALLOW_FROM="10.0.0.1-10.0.0.5,192.168.0.0/22"
+DENY_FROM="all"
+POLICY="allow"
+----
+
+IP addresses can be specified using any syntax understood by `Net::IP`. The
+name `all` is an alias for `0/0`.
+
+The default policy is `allow`.
+
+[width="100%",options="header"]
+|===========================================================
+| Match                      | POLICY=deny | POLICY=allow
+| Match Allow only           | allow       | allow
+| Match Deny only            | deny        | deny
+| No match                   | deny        | allow
+| Match Both Allow & Deny    | deny        | allow
+|===========================================================
+
+
+SSL Cipher Suite
+----------------
+
+You can define the cipher list in `/etc/default/pmgproxy`, for example
+
+ CIPHERS="ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256"
+
+Above is the default. See the `ciphers(1)` man page from the `openssl`
+package for a list of all available options.
+
+The first of these ciphers, available to both the client and the `pmgproxy`,
+will be used.
+
+Additionally you can allow the client to choose the cipher from the list above
+by disabling the HONOR_CIPHER_ORDER option in `/etc/default/pmgproxy`:
+
+ HONOR_CIPHER_ORDER=0
+
+
+Diffie-Hellman Parameters
+-------------------------
+
+You can define the used Diffie-Hellman parameters in
+`/etc/default/pmgproxy` by setting `DHPARAMS` to the path of a file
+containing DH parameters in PEM format, for example
+
+ DHPARAMS="/path/to/dhparams.pem"
+
+If this option is not set, the built-in `skip2048` parameters will be
+used.
+
+NOTE: DH parameters are only used if a cipher suite utilizing the DH key
+exchange algorithm is negotiated.
+
+COMPRESSION
+-----------
+
+By default `pmgproxy` uses gzip HTTP-level compression for compressible
+content if the client supports it. This can be disabled in `/etc/default/pmgproxy`
+
+ COMPRESSION=0
