-## Generating the Changelog
-We use [github-changelog-generator](https://github.com/github-changelog-generator/github-changelog-generator) to 
-generate release Changelogs. To be consistent with previous Changelogs, the following flags should be passed to the 
-command:
-
-```
---user vulcanize
---project vulcanizedb
---token {YOUR_GITHUB_TOKEN}
---no-issues
---usernames-as-github-logins
---since-tag {PREVIOUS_RELEASE_TAG}
-```
-
-More information on why your github token is needed, and how to generate it here:
