I work for MaxMind and it was pointed out to me that a popular blog post of ours around here was [this post from 2015](https://blog.maxmind.com/2015/09/29/building-your-own-mmdb-database-for-fun-and-profit/) showing how to build an MMDB using Perl. Well, it's 2020 now and we've got a post showing how to [enrich your MMDB files using Go](https://blog.maxmind.com/2020/09/01/enriching-mmdb-files-with-your-own-data-using-go/) now. Just wanted to let you all know. If you have any questions feel free to reply here or create an issue in the github repo. ---
