 - `max_kernel`: The maximum kernel version on which the program should be deployed.
 - `min_kernel`: The minimum kernel version on which the program should be deployed.
 
-You can use the `TraceProgram` object to deploy different BPFtrace programs based on the kernel version of the nodes in your cluster. For example, you might have one version of a BPFtrace program that works on kernel versions up to 5.18, and another version that works on kernel versions 5.19 and above. You can define two `TraceProgram` objects and use them both in the `UpsertTracepoint` function.
