1. Create config

export default {
    routes: {...}
}

2. Create rewrites in next.config.js - when changing config, save next.config.js to reset rewrites

const createRewrites = require('@alt-digital/next-i18n-routes/dist/cjs/createRewrites')
const rewrites = createRewrites('[config path]')

module.exports = {
    async rewrites() {
        return {
            beforeFiles: rewrites
        }
    },
    ...

3. Create utils

import { createRouting } from '@alt-digital/next-i18n-routes'
import config from '[config path]'

export const { Link, useRouter, getLocaleHref } = createRouting(config)
