# Strelka2 | |||||
You don't need to tune the parameters of strelka. It bases on [trained models](<https://github.com/Illumina/strelka/blob/v2.9.x/docs/userGuide/trainingGermlineEmpiricalScore.md>), you may train new models to improve performance. | |||||
Why? | |||||
Two steps: | |||||
1. Generate the configuration | |||||
```bash | |||||
``` | |||||
2. Run Strelka | |||||
```bash | |||||
``` | |||||
