 To do this, ensure that you have the following dependencies:
 
 ```clojure
-[org.slf4j/slf4j-api          "x.y.z"] ; >= 2.0.0
+[org.slf4j/slf4j-api          "x.y.z"] ; >= 2.0.0 only!
 [com.taoensso/slf4j-telemere  "x.y.z"]
 ```
 
+> Telemere needs SLF4J API **version 2 or newer**. If you're seeing `Failed to load class "org.slf4j.impl.StaticLoggerBinder"` it could be that your project is importing the older v1 API, check with `lein deps :tree` or equivalent.
+
 When `com.taoensso/slf4j-telemere` is on your classpath AND no other SLF4J backends are, SLF4J will direct all its logging calls to Telemere.
