Remove all references to metadata from README.md to avoid confusion.

[nelsonic]

It appears that the metadata section in the README.md #what-about-metadata was confusing ... #19
We don't need to introduce people to the concept of metadata at all.
So I have completely removed it and replaced it with a section about displaying the count in the UI.

Perhaps if Metadata does not enter this application as a necessary tool it would be better to remove it so as not to cause any doubt.
Unless I was the only one asking.

@miguelmartins17 it's always helpful to have a completely fresh perspective on things.
Yes, there have been hundreds of people who have read/followed this tutorial and not been confused by the section on metadata. But that doesn't matter. What matters is the one person who does get confused by it and it halts their progress. The last thing I want is for anyone to "halt and catch fire" ...
So I thank you for highlighting that the tutorial needlessly introduces a complex topic!
I re-read the section with fresh eyes and determined that it can be re-written to remove the concept of metadata completely.

Wrong button was trying to approve this request. 😨
I'll keep learning more about Git, I still have a lot to improve.

@miguelmartins17 generally when a Pull Request is assigned to a specific person, it is that person's responsibility to review and merge. 🙄
I requested a review from you, but the PR was assigned to @iteles for her to read and confirm that what I have changed makes sense before being merged. 💭
Please bare that mind in future.
Sorry if it wasn't clear in https://github.com/dwyl/contributing
We will need to make it clear in future to avoid by confusion. 👍

It makes sense, my goal was really just to approve this review not to merge.
It was my mistake, not yours, and I didn't mean to, but I thought that the button would just say that I approve, not that I would merge the requests.
