-The client formerly resided in the [Tox core repository](https://github.com/irungentoo/ProjectTox-Core) and is now available as a standalone program. It looks like [this](http://wiki.tox.im/images/b/b6/Ncursesclient1.png).
+Toxic is an ncurses based instant messaging client for [Tox](http://tox.im) which formerly resided in the [Tox core repository](https://github.com/irungentoo/ProjectTox-Core) and is now available as a standalone program. It looks like [this](http://i.imgur.com/hL7WhVl.png).
+## Installation
+* Generate the configure script by running the ```autoreconf -i``` command.
 
-To compile, first generate the configure script by running the ```autoreconf -i``` command.
+* Execute the configure script with ```./configure``` (you may need to pass it the location of your dependency libraries, i.e.):
+```./configure --prefix=/where/to/install --with-libtoxcore-headers=/path/to/ProjectTox-Core/toxcore --with-libtoxcore-libs=/path/to/ProjectTox-Core/build/.libs --with-libsodium-headers=/path/to/libsodium/include/ --with-libsodium-libs=/path/to/sodiumtest/lib/ ```
 
-Then execute the configure script with ./configure (you may need to pass it the location of your dependency libraries, i.e.):
-```
-./configure --prefix=/where/to/install --with-libtoxcore-headers=/path/to/ProjectTox-Core/core --with-libtoxcore-libs=/path/to/ProjectTox-Core/build/core --with-libsodium-headers=/path/to/libsodium/include/ --with-libsodium-libs=/path/to/sodiumtest/lib/
+* Audio calling support requires openal installed
+* Compile with --disable-av to build without audio call support
+* Compile and install the program with ```make && sudo make install```
 
-```
-*Note:* If your default prefix is /usr/local and you happen to get an error that says "error while loading shared libraries: libtoxcore.so.0: cannot open shared object file: No such file or directory", then you can try running ```sudo ldconfig```. If that doesn't fix it, run:

+## Settings
+After running Toxic for the first time an empty file called toxic.conf should reside in your home configuration directory (~/.config/tox for Linux users). For an example on how to use this config file to save settings such as auto-logging and time format see: toxic/misc/toxic.conf

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also link it with them as well. e.g. you should link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threads programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.
