+# Commercetools SheerID discount codes
+
+This is a quick overview of how to integrate [SheerID verification](https://www.sheerid.com/) to your commercetools (https://www.commercetools.com/) site without automatic processes.
+
+## Requirements
+- a commercetools website, access to Merchant Center with a user that has access to the Settings > Developer settings > API keys
+- a SheerID account
+- computer with nodejs v16 or not much higher (should work from v10 and with recent versions but no guarantees)
+
+## Installation 
+
+Preparation, this process does not install anything outside of the cloned folder.
+
+- clone the repository to your local machine
+- run `yarn` or `npm install` to install the dependencies
+
+## The process
+
+How to use:
+- Create a cart discount on your system (e.g. 20% off for students)
+- Create a commercetools API client in Merchant Center > Settings > Developer settings > API clients
+    - Scope can be "Admin client" (not recommended) or "Manage" Cart discounts and Discount codes
+    - Download the created API client's "Environment variables (.env)" file before closing the popup
+    - Add the .env file to the project root
+- Run `node get-cart-discounts.js`, copy the desired ID (UUID format, like `f9c4718e-0792-4f08-a802-70f81ef9d46d`)
+- Run `node generate-discount-codes.js STUD20- f9c4718e-0792-4f08-a802-70f81ef9d46d 20 > newcodes.csv`
+- Check `newcodes.csv` for the generated discount codes
+- Sanity check the generated discount codes in Merchant Center > Discounts > Discount code list
+- Test code behaviours in the cart without using them, or by removing the used up codes from the csv
+- On https://my.sheerid.com/ 
+    - Create a SheerID program, e.g. "Student discount"
+    - Upload `newcodes.csv` to the Codes step "Single-Use Codes" card
+    - Copy the Web URL from Publish step "New Page"
+
+- Add the copied Web URL to your website as a banner link or button
+- Test linked banner on your website, fill the form, copy the code and test cart and checkout (the code will be invalidated in SheerID system immediately after successful verification)
+- Don't forget to switch the program to Live mode on https://my.sheerid.com/
