+ - Look for run scripts in the `package.json` file for getting browser minified and non-minified builds. The builds are updated in the `dist` folder of the directory. Among the others, the important ones are: 			  
+     - `npm run buildProdBrowser` : This outputs  **rudder-analytics.min.js**.
+     - `npm run buildProdBrowserBrotli`: This outputs two files, **rudder-analytics.min.br.js** (the original minified file, same as above) and **rudder-analytics.min.br.js.br** (the brotli compressed file).
+     - `npm run buildProdBrowserGzip`: This outputs two files, **rudder-analytics.min.gzip.js** (the original minified file, same as above) and **rudder-analytics.min.gzip.js.gz** (the gzipped compressed file).
+     We are using **rollup** to build our SDKs, configuration for it is present in `rollup.config.js` in the repo directory.
