+## Include using a script tag (not recommended)
+
+If it's not possible to work with node modules, `json2csv` can be declared as a global by requesting `dist/json2csv.js` via an HTML script tag:
+
+```
+<script src="node_modules/json2csv/dist/json2csv.js"></script>
+<script>
+  console.log(typeof json2csv === 'function'); // true
+</script>
+```
+
+### Building
+
+When developing, it's necessary to run `webpack` to prepare the built script. This can be done easily with `npm run build`.
+
+If `webpack` is not already available from the command line, use `npm install -g webpack`.
