 ## How To Decide Which Installation Method To Use
 
-Most node applications today are either written in CommonJS (CJS), or compiled to CJS before running them.
-CommonJS uses `require()` to load modules. Our recommended installation method when using CommonJS is to require the `instrument.js` file at the top of your application. However, if your application is run in ESM mode, this will not work, in which case you can follow the [ESM docs](./esm).

 Note that even if your application is written in ESM (using `import`), it may still be _run_ in CJS. In this case, you should follow the [CommonJS instructions](./commonjs).
