Recently I've installed a package. After that I read an instruction how to use the package.
When I began to use I found an error in the instruction.
If you initialize package as written in an example you will get the error as on attached image below

I decided to see how the package was written and in some time I understood where the error was. It was in the instruction. Maybe, you forgot to change it after updating the package.
Now, you can see on attached image below that I've fixed.

That's why I've wanted to create a pull request in order to other people can use the package without problem.
