 A Clojure app to report and log the current number of users in the fediverse.
 
+This app depends on the API provided by [instances.social](https://instances.social/api/);
+I have not investigatged the methodology by which they assemble their list of instances. In
+any case it's impossible to tell how many of those accounts represent real individual human
+users, and I don't currently do anything to establish how many of those accounts are active.
+
+Please don't use this app to DDoS `instances.social`; it really shouldn't be necessary to run
+it more than once a day.
+
 ## Configuring
 
 You should obtain a key from [instances.social](https://instances.social/api/token) and write it (just the file, nothing else) into `resources/secret.txt`.
