Steps:

1. run yarn
2. run yarn outdated to see which packages to update. example:

   Package                    Current Wanted  Latest  Package Type    URL                                                                                      
   @material-ui/core          4.10.0  4.10.2  4.10.2  dependencies    https://material-ui.com/
   eslint                     7.1.0   7.2.0   7.2.0   devDependencies https://eslint.org
   gatsby                     2.22.13 2.23.3  2.23.3  dependencies    https://github.com/gatsbyjs/gatsby/tree/master/packages/gatsby#readme
   

3. run yarn add <dependencies...> where <dependencies...> refer to a space-separated list of dependencies shown as outdated in the step above. example:
   $ yarn add @material-ui/core gatsby
4. run yarn add --dev <devDependencies...> where <devDependencies...> refer to a space-separated list of devDependencies shown as outdated in step 2. example:
   $ yarn add --dev eslint
5. run yarn upgrade
6. run yarn develop and make sure everything still works
