 ## Examples
 
-This directory contains examples of tracing applications using the sqlalchemy package. To run the examples, make sure you've installed the packages `opentracing` and `lightstep`. If you have a lightstep token and would like to view the created spans, then uncomment to proper lines under the given examples. If you would like to use a different OpenTracing implementation, you may also replace the lightstep tracer with the tracer of your choice.
+This directory contains examples of tracing applications using the sqlalchemy package. To run the examples, make sure you've installed the package `opentracing`. If you have access to a tracing platform and would like to view the created spans, replace the `tracer` in the example files with the tracer of your choice.
