-AdAstra Utility Scripts
+A collection of utility scripts for AdAstra projects. Each script is self-contained and can be used independently.
+
+## Scripts
+
+### MongoDB
+
+| Script | Description |
+|---|---|
+| [`dbdump_mongo/`](dbdump_mongo/) | Backup MongoDB databases with multi-environment support (prod, uat, staging, …) |
+| [`dbrestore_mongo/`](dbrestore_mongo/) | Restore a MongoDB backup with interactive directory navigation |
+| [`dbutils_mongo/`](dbutils_mongo/) | Spin up a local MongoDB + Mongo Express instance via Docker |
+
+#### Typical MongoDB workflow
+
+```bash
+# 1. Backup from a remote MongoDB
+cd dbdump_mongo && ./db-dump.sh dump
+
+# 2. Start a local MongoDB instance
+cd dbutils_mongo && ./db-start.sh up
+
+# 3. Restore the backup locally
+cd dbrestore_mongo && ./db-restore.sh
+```
+
+## Requirements
+
+Each script lists its own requirements in its README. Common dependencies:
+
+- **Bash**
+- **MongoDB Database Tools** (`mongodump` / `mongorestore`) — [download](https://www.mongodb.com/try/download/database-tools)
+- **Docker & Docker Compose** (for `dbutils_mongo` only)
