 Hi there!
 Many thanks for taking an interest in improving nf-core/rnafusion.

 1. Check that there isn't already an issue about your idea in the [nf-core/rnafusion issues](https://github.com/nf-core/rnafusion/issues) to avoid duplicating work. If there isn't one already, please create one so that others know you're working on this

 ### Default processes resource requirements
 
-Sensible defaults for process resource requirements (CPUs / memory / time) for a process should be defined in `conf/base.config`. These should generally be specified generic with `withLabel:` selectors so they can be shared across multiple processes/steps of the pipeline. A nf-core standard set of labels that should be followed where possible can be seen in the [nf-core pipeline template](https://github.com/nf-core/tools/blob/master/nf_core/pipeline-template/conf/base.config), which has the default process as a single core-process, and then different levels of multi-core configurations for increasingly large memory requirements defined with standardised labels.
