 If you are parsing HTML with SVG code you can set `lowerCaseTags` to `true` without having to enable `xmlMode`. Keep in mind this will return all tag names in camel-case and not the HTML standard of lowercase.
 
 > **Note**: If you are parsing code client-side (in-browser), you can not control the parsing options. Client-side parsing automatically handles returning some HTML tags in camel-case, such as specific SVG elements, but returns all other tags lowercased according to the HTML standard.
 
-## Testing
-
-Run server and client tests:
-
-```sh
-npm test
-```
-
-Generate HTML coverage report for server tests:
-
-```sh
-npx nyc report --reporter=html
-```
-
-Lint files:
+## Migration
 
-```sh
-npm run lint
-npm run lint:fix
-```
+### v5
 
-Test TypeScript declaration file for style and correctness:
+Migrated to TypeScript. CommonJS imports require the `.default` key:
 
-```sh
-npm run lint:dts
+```js
+const parse = require('html-dom-parser').default;
 ```
