 ## Generate templates
 
 This is the command-line equivalent of using the schematic API or using the DCA UI to generate a template.
 
-1. For generating templates, you need creds. (You only need to do this once with a new codespace. Locally, we can keep the `creds.json` In the command line and gitignore it so it is not committed to the repo.) Run the bash script `./scripts/setup_creds.sh`. You should see a `creds.json` file at the root of the repo, next to the `.jsonld` file, etc. Feel free to skim the bash script and the `.json` file.

-2. Generate a blank Excel template for e.g. scRNAseq-Level1 by running `./scripts/new_template.sh ImagingLevel2`. This generates an Excel template by default. Try replacing with another template ID. Try also copy-pasting contents of the script to the command-line to run schematic command natively, replacing variables as needed.
