 - Shared helpers should be added to the [`packages/core-js/internals`](./packages/core-js/internals) directory. Reuse already existing helpers.
 - For export the polyfill, in all common cases use `internals/export` helper. Use something else only if this helper is not applicable - for example, if you want to polyfill accessors.
 - If the code of the pure version implementation should significantly differ from the global version (*that's not a frequent situation, in most cases `internals/is-pure` is enough*), you can add it to [`packages/core-js-pure/override`](./packages/core-js-pure/override) directory. The rest parts of `core-js-pure` will be copied from `core-js` package.
-- Add the feature detection of the polyfill to [`tests/compat/tests.js`](./tests/compat/tests.js), add the compatibility data to [`packages/core-js-compat/src/data.mjs`](./packages/core-js-compat/src/data.mjs) and the name of the polyfill module to [`packages/core-js-compat/src/modules-by-versions.mjs`](./packages/core-js-compat/src/modules-by-versions.mjs) (this data also used for getting the default list of polyfills at bundling).

 - Add it to entry points where it's required: directories [`packages/core-js/es`](./packages/core-js/es), [`packages/core-js/stable`](./packages/core-js/stable), [`packages/core-js/actual`](./packages/core-js/actual), [`packages/core-js/features`](./packages/core-js/features), [`packages/core-js/proposals`](./packages/core-js/proposals), [`packages/core-js/stage`](./packages/core-js/stage) and [`packages/core-js/web`](./packages/core-js/web).
 - Add unit tests to [`tests/tests`](./tests/tests) and [`tests/pure`](./tests/pure).
 - Add tests of entry points to [`tests/commonjs.js`](./tests/commonjs.js).
