 ### Opening an issue to report a bug
 
-It is essential that you provide an [SSCCE](http://sscce.org/)/[MCVE](https://stackoverflow.com/help/minimal-reproducible-example) for your issue. You can use the [papb/sequelize-sscce](https://github.com/papb/sequelize-sscce) repository. Tell us what is the actual (incorrect) behavior and what should have happened (do not expect the maintainers to know what should happen!). Make sure you checked the bug persists in the latest Sequelize version.
