add readme & makefile + small typo fixes.

Maybe we should document for the none programmer, that currently, if
notifycmd is set, the -DNOTIFY part is skipped.

-spt - simple pomodoro timer
-===========================
-spt is a simple timer that uses the pomodoro technique that doubles your
-efficiency.
+# pomo - a simple pomodoro timer
 
-Features
---------
-- Get the jobs done quicker than ever
-- Keeps you free like a dog
-- Able to show remaining time
+## about
 
-Installation
-------------
-Edit config.mk to match your local setup (spt is installed into the /usr/local
-namespace by default).
+pomo is a simple timer that uses the pomodoro technique. It is based on [spt](https://github.com/pickfire/spt), which is a bit less simple. 
 
-Afterwards enter the following command to build and install spt (if necessary
-as root):
+## dependencies
 
-    make clean install
+Instead of inotify, this pomodoro timer uses [sent](https://tools.suckless.org/sent/), displaying messages to the user by spawning a process that calls `echo 'msg' | sent`.
 
-See the man pages for additional details.
+## installation
 
-Configuration
--------------
-The configuration of spt is done by creating a custom config.h and
-(re)compiling the source code. By default, the timer runs by 4
-pomodoro timer (25 mins) with subsequent rests in between (15 mins)
-followed by a long rest (5 mins) in an infinite loop.
+Read pomo.c, then:
 
-Links
------
-http://pomodorotechnique.com/
+```
+make
+sudo make install
+```
 
+## usage
 
-The project is licensed under the MIT license.
+In a terminal, call the "pomo" command. Then, an initial message will appear in its own window. Close it and start working. By default, the timer runs by 4 pomodoro timer (25 mins) with subsequent rests in between (5 mins) followed by a long rest (15 mins) in an infinite loop.
+
+## configuration
+
+read through the <60 lines of C, and change as appropriate. If this functionality is too simple, consider looking at [spt](https://github.com/pickfire/spt) instead.
