-## Toxic
+# Toxic
 
 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/toxcore --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.):
+* Compile and install the program with ```make && sudo make install```
-```
-./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/
 
-```
+#### Notes
-*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:
+If your default prefix is /usr/local and you get the error: "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:
