 ### Adding users
 
-- To add more users to your email server, open up [`users.yaml`](https://github.com/LSFLK/silver/blob/main/conf/users.yaml), and add their usernames and run the following command.
+Users in Silver are provisioned through the [Thunder ID](https://github.com/thunder-id/thunderid) console that ships with the platform. Sign in to the console at `https://<your-domain>:8090/console` with your admin credentials.
 
-```bash
-# silver/services
-bash scripts/user/add_user.sh
-```
-- Once you have added the users, `user_invite_urls.txt` will be generated in `scripts/user` folder with invite links for each user. You can share these links with the respective users to set up their accounts.
+For the full walkthrough — creating a user schema, assigning it to an organization unit, and adding users via direct password or invitation link — see [Adding Users](docs/Adding-Users.md).
 
 ### Testing your setup
 - Now that you have a working email server, you can test your configuration using the following links/scripts.

+# Adding Users
+
+Users in Silver are provisioned through the [Thunder ID](https://github.com/thunder-id/thunderid) console that ships with the platform. This guide walks through adding users via the console.
+
+## Prerequisites
+
+- Silver is running (see [Server Setup](../README.md#server-setup) in the main README).
+- You can reach the Thunder console at `https://<your-domain>:8090/console`.
+- You have Thunder admin credentials.
+
+## Steps
+
+### 1. Sign in to the Thunder console
+
+Open `https://<your-domain>:8090/console` in your browser and sign in with your admin credentials.
+
+### 2. Create a user schema
+
+Define a user schema that includes the fields needed for an email user — at minimum, `username` and `password`.
+
+### 3. Assign the schema to an organization unit
+
+Assign the schema you just created to the organization unit you want the users to belong to.
+
+### 4. Add users
+
+Under the target organization unit, add users using one of the following:
+
+- **Set a password directly** — supply a `username` and `password` for the user.
+- **Send an invitation link** — provide the user's secondary email address; Thunder will email them an invitation link to set their own password.
