-## Basic Usage
-View the full documentation [here](https://emctoolkit.vercel.app/docs/npm).
-
+## Import
+By default, the available maps are exported and can be used like so:
 ```ts
 import { Aurora } from 'earthmc' // ESM
 const { Aurora } = require('earthmc') // CJS
+```
 
+However, you may want to create your own map instance to customize the expiry time of the cache.
+```ts
+import { Squaremap, Dynmap } from 'earthmc'
+
+const Aurora = new Squaremap('aurora', 10) // Default Squaremap TTL is 30s.
+const Nova = new Dynmap('nova', 90) // Default Dynmap TTL is 120s.
+```
+
+## Basic Usage
+Visit the [documentation](https://emctoolkit.vercel.app/docs/npm) to use this library to its full potential.
+
+```ts
 const towns = await Aurora.Towns.all().catch(console.error)
 console.log(towns.length)
-```
+
+// These calls are instant since the previous call to `all()` populated the cache.
+const single = await Aurora.Towns.get('exampleName')
+const many = await Aurora.Towns.get('town1', 'town2', 'town3', ...)
+```
+
+### GPS
+In addition to the four main classes (Towns, Nations, Residents, Players), both maps also provide a GPS.
+Here is an example of how you could use it.
+```ts
+// To avoid PVP, call `safestRoute` instead.
+const route = await Aurora.GPS.fastestRoute({ x: town.x, z: town.z })
+const desc = `Type **/n spawn ${route.nation.name}** and head **${route.direction}** for **${route.distance}** blocks.`
+```
+
+To continously track a player, you can use the `track` method.
+  - First parameter (player name) is **required**, but case insensitive.
+  - Second parameter (interval) is optional. Defaults to `3000` milliseconds.
+  - Third parameter (route) is optional. Defaults to `FASTEST`.
+```ts
+// Start tracking a player, with 5s delay, outputting the safest route.
+const tracker = await Aurora.GPS.track("PlayerName", 5000, Routes.SAFEST).catch(e => {
+    console.error("Error fetching player: " + e)
+})
+
+// Listen for any errors that may occur.
+tracker.on('error', e => {
+    console.error("An error occurred: " + e)
+})
+
+tracker.on('underground', (playerInfo) => {
+    console.log("Player went underground - " + playerInfo)
+})
+
+tracker.on('locationUpdate', (routeInfo) => {
+    console.log("Player's location updated - " + routeInfo)
+})
+```
