Adding theme configuration for output and guideline practices and other proposals

[wilmeragsgh]

Hi! I hope you're doing well in this complex time.

First of all, I wanted to thank you for the initial code as it helped me in getting ready again for the job search process as I couldn't continue where I worked for COVID-19 logistic issues.

That said, I want to propose you adding the following:

• Themes for output: As I think people read mostly digitally anyway it could be more readable if we include it right in the output.

• Adding references for up-to-date versions of the URL: So if anyone has a legacy version it can go to the latest one anytime.

• Adding guidelines for structuring the entries: I was looking for some recommendations and found those to make sense and also to be trustable.

• Switching from project name to a milestone achieved approach: This as one of the recommendations in the guidelines and also to make it difficult to be vague while using the template, which I think could help other people.

That's it, let me know what you think, and thanks again! :wave:
