------------------------------------
+## 🌠 Version without a local database
 This module requires a significant amount of RAM because geolocation data is stored in memory. Nevertheless, you can always use the official and alternative [geoip2-api](https://www.npmjs.com/package/geoip2-api) module, which sends a request to the API server and retrieves information about a specific IP address from there.

 You can see this module in action using my [official API](https://sefinek.net). Generally speaking, the API interface is public, and you can safely use it in your projects. Happy coding!

-📑 Introduction
----------------
+## 📑 Introduction
 MaxMind provides a set of data files for IP to Geo mapping along with opensource libraries to parse and lookup these data files.
 One would typically write a wrapper around their C API to get access to this data in other languages (like JavaScript).

-📚 Philosophy
--------------
+## 📚 Philosophy
 I was really aiming for a fast JavaScript native implementation for geomapping of IPs.
 My prime motivator was the fact that it was really hard to get libgeoip built for Mac OSX without using the library from MacPorts.
 
 
-🕵️‍♂️ Why GeoIP-Lite?
-------------------
+## 🕵️‍♂️ Why GeoIP-Lite?
 GeoIP-Lite is a fully JavaScript implementation of the MaxMind GeoIP API. It is not as fully featured as bindings that use `libgeoip`.
 By reducing scope, this package is about 40% faster at doing lookups. On average, an IP to Location lookup should take 20 microseconds on
 a Macbook Pro. IPv4 addresses take about 6 microseconds, while IPv6 addresses take about 30 microseconds.

 GeoIP-Lite2 is completely synchronous. There are no callbacks involved.
 All blocking file IO is done at startup time, so all runtime calls are executed in-memory and are fast.
 Startup may take up to 200ms while it reads into memory and indexes data files.

+## 🔀 Alternatives
 If your use-case requires doing less than 100 queries through the lifetime of your application or if you need really fast latency on start-up, you might want to look into [fast-geoip](https://github.com/onramper/fast-geoip) a package with a compatible API that is optimized for serverless environments and provides faster boot times and lower memory consumption at the expense of longer lookup times.
