 This Mastodon bot transfers the trends from other instances directly to your personal timeline. You decide which instances it fetches and how much you want to see per instance.
 
 ## Why
-I am hosting my own mastodon instance and my server is very small (~2 active users). This is why trends simply do not work on my instance. There is just not enough activity. I used to open up the explore-pages of other interesting mastodon instances once per day to discover interesting topics and posts beyond my subscriptions. But that is a bit tedious in the long run. One afternoon I decided to write a bot for this issue and here we are :tada:
+
+For smaller instances the local timeline is rather empty. This is why trends simply do not work on those instances: There is just not enough activity. Instead of manually checking out other instances this bot allows to subscribe to a multitude of different mastodon compatible servers to fetch trending posts and repost them to your current server helping discoverability of accounts, people and topics within the federated social web.
