# Localizing a website based on current country or city
In this tutorial, we show you how to use the Radar [web SDK](/sdk/web) and [IP geocoding API](/api#ip-geocode) to localize a website based on current country or city.
For example, you may show a default language or currency based on current country. Or, you may show nearby content based on current city.

## Steps
If you haven't already, sign up for Radar to get your API key. You can make up to 100,000 API requests per month for free.

In an HTML page, include the SDK using a `
```
In a web app, install the package from npm, then import the library:
```
npm install --save radar-sdk-js
```
```
import Radar from 'radar-sdk-js';
```
The [IP geocoding API](/api#ip-geocode) converts IP address into city, state, and country.
Initialize the SDK with your publishable API key, then call the IP geocoding API.
In the callback, `result.address` will include `countryCode`, `stateCode`, `city`, coarse `latitude` and `longitude`, and more.
```javascript theme={null}
Radar.initialize("prj_test_pk_...");
Radar.ipGeocode(function(err, result) {
if (err) {
console.error(err);
return;
}
if (result && result.address) {
// do something with result.address.countryCode
}
});
```
## Sample code
```html theme={null}
Hello, world!
Loading...
```
