 # salty-ircd
-
 salty-ircd is an [Internet Relay Chat](https://en.wikipedia.org/wiki/Internet_Relay_Chat) daemon written in [D](https://dlang.org/).
 
 ## Goals
 The main goals of salty-ircd are strict RFC compliance and security.
 
 ### RFC compliance
-salty-ircd aims to be fully compliant with the IRC RFCs (in 'RFC mode'), specifically [RFC 1459](https://tools.ietf.org/html/rfc1459), [RFC 2811](https://tools.ietf.org/html/rfc2811), [RFC 2812](https://tools.ietf.org/html/rfc2812), and [RFC 2813](https://tools.ietf.org/html/rfc2813) (planned).
-Newer RFCs take precedence over older RFCs. Errata are respected by default, with newer errata (on the same RFC) taking precedence over older errata.

-Any additional features breaking RFC compliance will be made available through compile-time options (i.e. 'non-RFC modes').
+Any additional features breaking RFC compliance are available through compile-time options.
 
-### Security (non-RFC modes)
- * salty-ircd will require TLS for all connections. An exception could be made to allow hosting a Tor hidden service.
- * salty-ircd will require TLS client certificates for authentication.
+### Security
+The following rules apply when any compile-time option is enabled (breaking strict RFC compliance):
+
+* TLS is required for all connections, except connections from localhost (useful for running a Tor hidden service, which already has encryption)
+* TLS client certificates are required for oper and vhost authentication
+
+## Building
+Build dependencies:
+* A D compiler
+* dub
+* fish
+* git
+
+Build command:
+* RFC compliant: `dub build`
+* With all additional features: `dub build -c=modern`
+
+TODO: Add a way to supply a custom list of compile-time options.
+
+## Running
+First, create the configuration file, `config.sdl`. You can find a template in `config.template.sdl`.
+
+Then, simply run `./out/salty-ircd`.
