+Various tasks will be run inside of Singularity containers and all temp files typically written to `/tmp` and `/var/tmp` are instead written to the path pointed to by the `USER_SCRATCH` environment variable. This means that these temp files are stored in a user specific location, making them inaccessible to other users for pipeline reruns. Some of these temp files can be large and cleanup is also the responsibility of the user.
+
 All of the intermediate files required to run the pipeline will be stored in the `work/` directory. It is recommended to delete this directory after the pipeline has finished successfully because it can get quite large, and all of the main output files will be saved in the `results/` directory anyway.
 
 > NB: You will need an account to use the HPC cluster on Cheaha in order to run the pipeline. If in doubt contact UAB IT Research Computing.</br></br>

+# nf-core/configs: HASTA rnafusion specific configuration
+
+Extra specific configuration for rnafusion pipeline
+
+## Usage
+
+To use, run the pipeline with `-profile hasta`.
+
+This will download and launch the rnafusion specific [`hasta.config`](../../../conf/pipeline/rnafusion/munin.config) which has been pre-configured with a setup suitable for the `HASTA` cluster.
+
+Example: `nextflow run nf-core/rnafusion -profile hasta`
+
+## rnafusion specific configurations for HASTA
+
+Specific configurations for `HASTA` has been made for rnafusion.
+
+- Always run all the analysis steps (all = true)
+- Use trimming (trim = true)
+- Take the fusions identified by at least 2 fusion detection tools to the fusioninspector analysis (fusioninspector_filter = true)
