 You can package, or just install directly by running, `sudo make isntall`.
 If you install using `make install`, don't forget to run, `sudo ./script/postinst`.
+```bash
+# Installation steps 
+$ cd build
+$ sudo ./script/preinst
+$ sudo make install 
+$ sudo ./script/postinst
+```

 I would suggest creating the package and then install it using your favorite
 package manager.  TO build your own pacakge you have to change the
 `CPACK_GENERATOR` in `install/CMakeList.txt` to what you like, possible options
 are, `DEB`, `RPM`, `STGZ` etc. (I am confusing the hell out of you. I know. I am
 confused too.)
 
+You can see your existing log, number of typos etc. using the `typtop` binary 
+installed in your `/usr/local/bin`. Try `$ typtop` and it will show you the options.
