diff: @@ -100,6 +100,22 @@ Use the `config-file` parameter of the `init` action to enable the configuration
  The configuration file must be located within the local repository. For information on how to write a configuration file, see "[Using a custom configuration](https://help.github.com/en/github/finding-security-vulnerabilities-and-errors-in-your-code/configuring-code-scanning#using-a-custom-configuration)."
  +If you only want to customise the queries used, you can specify them in your workflow instead of creating a config file, using the `queries` property of the `init` action:
  +
  +```yaml
  +- uses: github/codeql-action/init@v1
  + with:
  + queries: <local-or-remote-query>,<another-query>
  +```
  +
  +By default, this will override any queries specified in a config file. If you wish to use both sets of queries, prefix the list of queries in the workflow with `+`:
  +
  +```yaml
  +- uses: github/codeql-action/init@v1
  + with:
  + queries: +<local-or-remote-query>,<another-query>
  +```
