 ### Updating all Dependencies
 
-We use `npm update` to
-
-1. Obtain a fresh clone from “master”
-2. Run `./install.sh` and `./build.sh` to make sure the current HEAD is not broken (should never be...).
-3. Once build succeeded, run:
-    ```shell
-    $ npm update # to update the root deps
-    $ lerna exec npm update # to update deps in all modules
-    ```
-4. This will probably install some new versions and update `package.json` and `package-lock.json` files.
-5. Now, run `./build.sh` again to verify all tests pass.
-6. Submit a Pull Request.
