 ## Legacy notes
 
 * If you are searching for the legacy version based on [pdfjs](https://www.npmjs.com/package/pdfjs) please install a [v3 release](https://github.com/nbesli/pdf-merger-js/releases?q=v3&expanded=true). Since [v4](https://github.com/nbesli/pdf-merger-js/releases?q=v4&expanded=true) we use [pdf-lib](https://pdf-lib.js.org/) instead.
 * If you are searching for a legacy version using CommonJS modules please install a [v4 release](https://github.com/nbesli/pdf-merger-js/releases?q=v4&expanded=true). Since [v5](https://github.com/nbesli/pdf-merger-js/releases?q=v5&expanded=true) we use the modern ESM ("import") instead of the CommonJS ("require) module standard.
