Please complete the documentation by following the instructions in Document generation:

This plugin uses the ESLint eslint-doc-generator to generate consistent documentation.

• Install with npm install eslint-doc-generator -g
• Run eslint-doc-generator in the root directory of the plugin

There are some different terms to take care of:

• deprecated plugin is @cypress/xpath
• previously published as plugin cypress-xpath, related to an archived repository https://github.com/cypress-io/cypress-xpath. This plugin is also deprecated.
• API call is cy.xpath()

For consistency with other rules in the table https://github.com/cypress-io/eslint-plugin-cypress/blob/master/README.md#rules

I suggest that the description should be

"disallow using cy.xpath() calls"

Hi Mike, thanks for the comments. I've tried to address them - let me know what you think of it

[duranbe]

Wow thanks for the support. Indeed I see some changes in doc, I must have run the eslint-doc-generator in wrong way

Thanks for your initiative to resolve this request. 👍🏻 I have approved it as an external contributor.

We have to wait for the Cypress.io team to now review before it can be merged.
