+##  Create Migration File
+This repository includes a script for generating migration files in the `typescript/migrations` directory. The script automates the creation of migration files with a timestamped name and a basic template.
+
+To run the script, use the following command:
+```bash
+cd backend/typescript
+```
+```bash
+ts-node create-migrate.ts <name of migration>
+```
+Example:
+```bash
+ts-node create-migrate.ts create-applicant-table
+```
+##  Running Migrations
+To apply all pending migrations to the database, use the following command. This will execute the migration files sequentially and update the database schema:
+```bash
+docker exec recruitment_tools_backend node migrate up  
+```
