 ### Task Definition
 
-To evaluate the produced merges you need to specify a list of tasks supported by the LM evaluation harness. This can be either built in tasks (don't be naughty) or tasks you define yourself (see the [New Task Guide](https://github.com/EleutherAI/lm-evaluation-harness/blob/main/docs/new_task_guide.md) for how). If your task does not use `acc` as the metric then you must specify the correct metric name. Each task can also optionally have a weight associated.

 `mergekit-evolve` aims to maximize the score of the merge, so if you are using any tasks or metrics where a lower score is better (like perplexity) be sure to assign a negative weight to that task.
