Adding tags to archive

[e2-dunstan]

I'm not sure if I'm missing something obvious, but I can't for the life of me figure out how to include tags at the top of my page of posts. The posts themselves have tags (i.e. tags: [tag-here, another-tag]) but how would I get all the tags to appear at the top of the page (below navigation)? My website is e2-dunstan.github.io if you need to have a look. Thanks.
