+
+## Updating models
+
+To generate a new model from json data and overwrite the existing schema file:
+
+1. Copy and paste template `data-*.json` from [localization-tools](https://github.com/bigcommerce/localization-tools/blob/master/email-check/modules/email-templates/types/abandoned_cart_email/data-0.json) to `models/_json/email_templates`.
+2. Use `models/json2schema.py` to convert the json data to a yaml schema.
+
+Example:
+
+```bash
+cat data.json | python json2schema.py > schema.yml
+```
+
+Bash for overwriting all email template models:
+
+```bash
+for f in models/email_templates/data/*.json; do cat $f | python models/json2schema.py > ${f%.*}.yml; mv ${f%.*}.yml models/email_templates/; done
+```
