-Charybdis is a reference implementation of the IRCv3.1 server component. It is meant to be
-used with an IRCv3-capable services implementation such as [Atheme][atheme] or [Anope][anope].
+Charybdis is an IRCv3 server designed to be highly scalable. It implements IRCv3.1 and some parts of IRCv3.2.

# necessary requirements
* A supported platform
- * A working dynamic load library.
- * A working lex. Solaris /usr/ccs/bin/lex appears to be broken, on this system flex should be used.
+ * A working dynamic library system
+ * A working lex and yacc - flex and bison should work
+
+# platforms
+
+Charybdis is designed with portability in mind, but does not target older systems nor those of solely academic
+interest.
+
+Do note that operating systems are only supported if they are supported by their vendor.
+
+## Tier 1
+
+These platforms are the best supported, and should always work. They are actively tested. If you encounter
+problems, please file a bug.
+
+* FreeBSD 10.x and above (i386 and amd64)
+* Linux 2.6.x and above with glibc or musl (i386, x86_64, and ARM)
+* Mac OS X 10.7 and above
+* Windows Vista/Server 2008 and above (x86 or x64)
+
+## Tier 2
+
+These platforms are supported and occasionally tested, and most features should work, but this is not
+guaranteed. If you find any problems, file a bug, but as these are not regularly tested platforms, a timely
+resolution may not be possible.
+
+* DragonflyBSD 4.4 and above (i386)
+* Linux with uClibc (i386 or x86_64)
+* NetBSD 6.1.x and above (i386, amd64)
+* OpenBSD 5.6 and above (i386, amd64)
+* Solaris 10 and above (i386)
+
+## Tier 3
+
+Anything else that hasn't been tested. Charybdis may or may not work on it; patches welcome if they don't.
+
+# platform specific errata
+
+These are known issues and workarounds for supported platforms.
+
+ * **FreeBSD**: if you are compiling with ipv6 you may experience
+ problems with ipv4 due to the way the socket code is written. To
+ fix this you must: "sysctl net.inet6.ip6.v6only=0"
+
+ * **Solaris**: you may have to set your PATH to include /usr/gnu/bin and /usr/gnu/sbin before /usr/bin
+ and /usr/sbin. Solaris's default tools don't seem to play nicely with the configure script.
+
+# building from git
+
+We no longer supply a prebuilt configure script in git, due to use of automake and libtool causing problems.
+You will need to run `autogen.sh` to build the autotools files prior to building charybdis.
# feature specific requirements
(Using CHALLENGE is not recommended for new deployments, so if you want to use a different TLS library,
feel free.)
- * For ECDHE, OpenSSL 1.0.0 or newer is required. RHEL/Fedora and derivatives like CentOS
- will need to compile OpenSSL from source, as ECC/ECDHE-functionality is removed from
- the OpenSSL package in these distributions.
+ * For ECDHE, OpenSSL 1.0.0 or newer is required. Solaris; and RHEL/Fedora and its derivatives such as CentOS
+ have removed support for ECC/ECDHE. You will need to compile your own OpenSSL on these systems.
# tips
* Please read doc/index.txt to get an overview of the current documentation.
+ * Read the NEWS file for what's new in this release.
+
* The files, /etc/services, /etc/protocols, and /etc/resolv.conf, SHOULD be
readable by the user running the server in order for ircd to start with
the correct settings. If these files are wrong, charybdis will try to use
127.0.0.1 for a resolver as a last-ditch effort.
- * FREEBSD USERS: if you are compiling with ipv6 you may experience
- problems with ipv4 due to the way the socket code is written. To
- fix this you must: "sysctl net.inet6.ip6.v6only=0"
-
- * SOLARIS USERS: this code appears to tickle a bug in older gcc and
- egcs ONLY on 64-bit Solaris7. gcc-2.95 and SunPro C on 64bit should
- work fine, and any gcc or SunPro compiled on 32bit.
-
- * SUPPORTED PLATFORMS: this code should compile without any warnings on:
-
- * FreeBSD 10
- * Gentoo & Gentoo Hardened ~x86/~amd64/~fbsd
- * RHEL 6 / 7
- * Debian Jessie
- * OpenSuSE 11/12
- * OpenSolaris 2008.x?
- * Solaris 10 sparc.
-
- Please let us know if you find otherwise.
- It probably does not compile on AIX, IRIX or libc5 Linux.
-
- * Please read NEWS for information about what is in this release.

- * Other files recommended for reading: BUGS, INSTALL
