+### Axios support
+This tool allows you to generate a client based on the [`axios`](https://www.npmjs.com/package/axios) client.
+The advantage of the Axios client is that it works in both NodeJS and Browser based environments.
+If you want to generate the Axios based client then you can specify `--client axios` in the openapi call:
 
-### Node.js support
-> Since version 3.x [`node-fetch`](https://www.npmjs.com/package/node-fetch) switched to ESM only, breaking many
-> CommonJS based toolchains (like Jest). Right now we do not support this new version!
+`openapi --input ./spec.json --output ./dist --client axios`
 
-By default, this library will generate a client that is compatible with the (browser based) [fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API),
-however this client will not work inside the Node.js environment. If you want to generate a Node.js compatible client then
-you can specify `--client node` in the openapi call:
+The only downside is that this client needs some additional dependencies to work, due to the missing Blob and FormData
+classes in NodeJS.
+
+```
+npm install axios --save-dev
+npm install [email protected] --save-dev
+npm install [email protected] --save-dev
+npm install [email protected] --save-dev
+```
+
+In order to compile the project and resolve the imports, you will need to enable the `allowSyntheticDefaultImports`
+in your `tsconfig.json` file.
+
+```json
+{
+    "allowSyntheticDefaultImports": true
+}
+```
+
+
+### Node-Fetch support
+By default, this tool will generate a client that is compatible with the (browser based) Fetch API.
+However, this client will not work inside the Node.js environment. If you want to generate the Node.js compatible
+client then you can specify `--client node` in the openapi call:
 
 `openapi --input ./spec.json --output ./dist --client node`
 
 This will generate a client that uses [`node-fetch`](https://www.npmjs.com/package/node-fetch) internally. However,
-in order to compile and run this client, you might need to install the `[email protected]` dependencies:
