npm WARN package.json No repository field

When I do `yo angular` I get the below warnings:

npm WARN package.json todo@0.0.0 No repository field.
npm WARN package.json todo@0.0.0 No README data.

Searching on internet I found that it can be avoided by having a README.md file and the second warning can be avoided by using "repository" attribute in "package.json" but we already have "repository" attribute, maybe it requires an absolute URL? Please test!
