How to add tags to my content

Hi, I am new to Contentful and was exploring this product to be used for our business, now I am facing an issue here that I can not add tags to my contents. I referred few articles but it says only a few selected accounts have an option to add tags(not mine) and also they will not be given in Content delivery API and restricted only to Management API.

So What is a workaround for this? without attaching tags to my content we will not be able to suggest content for our users.
