Guidance on Documenting Project on Github/Blog posts

Hello, I had a question about rules/guidelines on documenting the project. This is my first Data Science project and Iā€™m interested in documenting my code/results/plots etc on Github or a Blog post to create a portfolio for myself, being new in the field. Want to know the extent to which the problem/dataset/details can be shared on such online portals keeping privacy of such competitions in mind. Thank you for your time and consideration! :slight_smile:
