The page does not specify the license, so people will be afraid of using it.

You should read all the possible licenses to ensure that people can use it as intended, but can not use in unexpected ways.

For example sometimes people choose CC0, and then get angry when other people redistribute it without attribution.

I suggest to take a look at https://creativecommons.org/share-your-work/ and once you have a rough ideas ask here for advice.
