Changes

Explain the changes that were made.

The idea is not to list exhaustively all the changes made (GitHub already provides a full diff), but to help the reviewers better understand:

• which specific file changes go together, e.g: when creating a table in the front-end, there usually is a config file that goes with it
• the reasoning behind some changes, e.g: deleted files because they are now redundant
• the behaviour to expect, e.g: tooltip has purple background color because the client likes it so, changed a key in the API response to be consistent with other endpoints

How to test

Explain how to test your PR.

If a specific config is required explain it here: dataset, account, profile, etc.

Notes

Things that the reviewers should know:

• known bugs that are out of the scope of the PR
• other trade-offs that were made
• does the PR depends on a PR in bluesquare-components?
• should the PR be merged into another PR?
