I was trying to use the plugin SuggestMe by Guilherme Lemos but it's asking for the Steam Web API Key.

I have some questions :

1. What is an API key ?

2. I tried to use the link suggested to get the api key and it requires me to enter a domain name. I don't have any website so how am I supposed to use it ?

3. Is it safe to put it in the plugin ?

Also just a little annoying but as the plugin is named SuggestMe it's quite impossible to find the github of the project because it's just flood with suggestions of plugins.
