 ### How to contribute mutations
 
 1. Fork this repository ([Do you need a GitHub account?](https://docs.github.com/en/get-started/signing-up-for-github/signing-up-for-a-new-github-account))  
-1. Copy `./import/mut_template.tsv` and name your file with an unique identifier using format:
-    [YYYYMMDD].[YourName].[0-9]{3}.tsv that can be used to link entries between the table and changelog (eg. `./20210812.Weigand.123.tsv`).    
+1. Copy `./import/mut_template.csv` and name your file with an unique identifier using format:
+    [YYYYMMDD].[YourName].[0-9]{3}.tsv that can be used to link entries between the table and changelog (eg. `./20210812.Weigand.123.csv`).    
 1. Enter mutation information according to the column descriptions below, entering 'NA' for any missing attributes except those marked as required. You may add multiple entries to this file.
 1. Save your new mutation file to `./import`.
 1. Commit your changes.
 1. Submit a pull request.
-1. Updated versions of `SCV2_mutations_latest.tsv` and `SCV2_mutations_latest.vcf` will be generated automatically when your pull request is approved.
