+## Modifying the Database Structure
+
+### Creating a Migration
+
+**Step 1:** Navigate to the corresponding folder within the project:
+```bash
+cd ROOT_PATH/server/db
+```
+
+**Step 2:** Execute the following command to create a new migration file:
+```bash
+npm run db:create-migration add_change_in_the_database_structure
+```
+
+This command creates a file in the migration folder named based on the provided argument. The generated file will have the following initial structure:
+```Javascript
+/**
+ * @param { import("knex").Knex } knex
+ * @returns { Promise<void> }
+ */
+exports.up = function(knex) {
+  // Add the changes that will be applied to the database
+};
+
+/**
+ * @param { import("knex").Knex } knex
+ * @returns { Promise<void> }
+ */
+exports.down = function(knex) {
+  // Add the changes that will revert the operations done in up
+};
+```
+
+#### Adapting to Asynchronous Functions:
+In the project, asynchronous functions are used by default. Modify the migration file to adhere to this standard:
+
+```Javascript
+exports.up = async (knex) => {
+  // Migration logic to apply changes
+};
+
+exports.down = async (knex) => {
+  // Migration logic to revert changes
+};
+```
+
+#### Implementation
+Implement the necessary logic in the up and down methods to apply or revert changes in the database. To understand how migrations work and explore detailed examples, refer to the [official Knex documentation on migrations](https://knexjs.org/guide/migrations.html#migration-api).
