Point your feature branch to use the `main` branch as the base of this PR. The exact commands used depends on how you've setup your local git copy, but the flow could look like this:

```sh
# Inside your own copy of `apexcharts.js` package...
git checkout --branch feature/branch-name-here upstream/main
# Then hack away, and commit your changes:
git add -A
git commit -m "Few words about the changes I did"
# Push your local changes back to your fork
git push --set-upstream origin feature/branch-name-here
```

After these steps, you should be able to create a new Pull Request for this repository. If you hit any issues following these instructions, please open an issue and we'll see if we can improve these instructions even further.
