  +### Releasing
  +
  +Make sure you have commit rights to the main `superset-ui-plugins-deckgl` repo, have checked it out (NOT a fork!) and
  +belong to the `superset-ui` org on npm (=can publish new versions).
  +
  +1. `yarn install`
  +2. `yarn build`
  +3. `yarn release-patch-version`. This will raise an error, but you should see a new commit and tag, e.g. `v0.4.8`
  +4. go to the DeckGL directory: `cd packages/superset-ui-legacy-preset-chart-deckgl`
  +5. make sure you're logged into npm: `npm whoami` should display your npm username.
  +6. `npm publish`
