No examples in the docs

There is not a single example of usage in the README. I created a file with some text with typos:

```
# test.txt
Hellp, my name is not rekevant.
```

Then I ran the command as specified but got nothing.

```
$ topy test.txt
Loaded 3729 rules (except 0 errors, 44 disabled)
```

Did it work but couldn't find any typos? Or am I doing something wrong and it didn't run properly?
