  -// TODO:
  +You may want to have a different configuration for one or more of your page functions. This is possible by setting the `pageConfig` key in the plugin config:
  -## Overriding specific page configuration
  +```yml
  +plugins:
  + - serverless-nextjs-plugin
  +
  +custom:
  + serverless-nextjs:
  + nextConfigDir: ./
  + pageConfig:
  + about:
  + memorySize: 512 # default is 1024
  + home:
  + timeout: 10 # default is 6
  +```
  +
  +The example above will deploy the `about` page function with a smaller `memorySize` and the home page with a higher `timeout` than the default values.
  -// TODO:
  +You can set any function property described [here](https://serverless.com/framework/docs/providers/aws/guide/functions#configuration). The values provided will be merged onto the defaults provided by the plugin.
