How do I credit someone when publishing a game?

Well I am preety close to finish my first game I created ,but I used assets from other people ,they are all general licence assets ,but I need to know how do I credit them ,how its done?

For any assets that you are able to use freely, the licence will specify how to provide attribution to the rights holder.

Ok I think I figured but I am not sure 100%.

When crediting author the credit should look like this:

                  website         - from where I took the asset
              >>insert link<<     - link to the asset ,there is also licence proof stated there
                author name       - full name or username of person who created the asset
