 The serving port can be changed with the `-p`/`--port` option.
 
+## Using with `Angular CLI`
+
+CORS issues when trying to use netlify-lambdas locally with angular? you need to set up a proxy.
+
+Firstly make sure you are using relative paths in your app to ensure that your app will work locally and on Netlify, example below...
+
+```js
+  this.http.get('/.netlify/functions/jokeTypescript')
+```
+
+Then place a `proxy.config.json` file in the root of your project, the contents should look something like...
+
+```json
+{
+  "/.netlify/functions/*": {
+    "target": "http://localhost:9000",
+    "secure": false,
+    "logLevel": "debug",
+    "changeOrigin": true
+  }
+}
+```
+
+- The `key` should match up with the location of your Transpiled `functions` as defined in your `netlify.toml`
+- The `target` should match the port that the lambdas are being served on (:9000 by default)
+
+When you run up your Angular project you need to pass in the proxy config with the flag `--proxy-config` like so...
+
+```bash
+  ng serve --proxy-config proxy.config.json
+```
+
+To make your life easier you can add these to your `scripts` in `package.json`
+
+```json
+  "scripts": {
+    "start": "ng serve --proxy-config proxy.config.json",
+    "build": "ng build --prod --aot && yarn nlb",
+    "nls": "netlify-lambda serve src_functions",
+    "nlb": "netlify-lambda build src_functions"
+  }
+```
+
+Obviously you need to run up `netlify-lambda` & `angular` at the same time.
+
 ## Webpack Configuration
 
 By default the webpack configuration uses `babel-loader` to load all js files. Any `.babelrc` in the directory `netlify-lambda` is run from will be respected. If no `.babelrc` is found, a [few basic settings are used](https://github.com/netlify/netlify-lambda/blob/master/lib/build.js#L11-L15a).
