 ### Keep `substrate-js-dev` repository up to date
 Sidecar is using [substrate-js-dev](https://github.com/paritytech/substrate-js-dev) repository as a dependency. For instance, running `yarn lint` in sidecar triggers the `substrate-dev-run-lint` script which is defined [here](https://github.com/paritytech/substrate-js-dev/blob/58fe47c55610a797c2e780c5cfef0f3dd2fae7ca/scripts/substrate-dev-run-lint.cjs). Therefore, it is important to keep this repository's dependencies up to date as well. This can be done by running `yarn upgrade-interactive` and following the process mentioned in the previous step. Last, we would need to make a new release in that repository and then update the package version in Sidecar.
