+# time-track
+
+A simple CLI tool for tracking how much time you have left to work. I find myself stressing about whether I'm hitting 8 real hours, so this little tool helps me avoid wasting
+time calculating when my work day will end.
+
+Simply enter times, one per line and send an EOF character when you're done. The first lines opens a span of work and the next line closes it so that you can build up working
+time be clocking in and out. Finally, you can send additional arguments to the program to configure how long you intend to work (the default is 8 hours).
+
+```
+❯ time-track
+Working for 8 hours
+Input times one per line. Send an EOF character to finish inputting...
+8:30
+9:30
+11:15
+12:30
+13:16
+18:20
+19:30
+20:11 # Send an EOF
+Exactly done
+```
