Hi @kbetty

Thanks for the change. Since you are working on it intensively, I ask you:
There is a major thing that is mistaken in our readme file. Can you spot what it is and correct it?

Welcome @GemmaTuron!

Yes as part of documentation, we need to have our docs well documented with clear information to the readers(user or contributors ).

Am excited to be part of the evolution, will take on the assigned task and will share my findings, perhaps suggest changes accordingly through a commit.

@GemmaTuron have gone through our Readme file carefully and Identified the following:

• Every section in the readme file there is a link(on the right bottom) that takes the reader back to the top of the page. This is repeated on every section of the readme file which I suggest we should get rid of.
  

• Some words in the paragraphs are capitalized of which some of them are supposed to be lowercase based on orthography. For example a statement like Low and Middle Income Country institutions should be written as low and middle income country institutions

Let me know if there is something have missed out so that I can fix it together with those that have identified above. Thanks
