By injecting the router, we get access to it as `this.$router` as well as the current route as `this.$route` inside of any component:

```js
// Home.vue
export default {
computed: {
username () {
// We will see what `params` is shortly
return this.$route.params.username
}

It might be nice to update this to a more real-world example. For example:

username () {
  // We will see what params are shortly
  return this.$route.params.username
}

},
methods: {
goBack () {
window.history.length > 1
? this.$router.go(-1)
: this.$router.push('/')
}

Again, a more real-world example could be helpful, so that readers can begin imagining when they might use this.$router. For example:

goBack () {
  window.history.length > 1
    ? this.$router.go(-1)
    : this.$router.push('/')
}

Another note: I'd probably avoid the word "redirect" here, as I think it implies an immediate transfer to another route in most cases - "navigate" or simple "go" are probably more appropriate.

Looks like we're missing a } here.

```

Throughout the docs, we will often use the `router` instance. Keep in mind that `this.$router` is exactly the same as using `router`. The reason we use `this.$router` is because we don't want to import the router in every single component that needs to manipulate routing.

You can also check out this example [live](http://jsfiddle.net/yyx990803/xgrjzsup/).

Notice that a `<router-link>` automatically gets the `.router-link-active` class when its target route is matched. You can learn more about it in its [API reference](../api/router-link.md).

Is it router-link.md or router-link.html?
