+# MongoDB Images
+
+## How to use this image
+
+
+- Build the image
+
+```bash
+docker build . -t mongo_stwp
+```
+
+- Run the container `docker compose up` to initialize the container
+
+- Edit the `./etc/mongo/mongod.conf`
+
+- If you want to use a keyfile, put it as `./etc/mongo/mongo.keyfile` anytime, the container will set right permissions to it automatically. (Optional)
+
+- Run `docker compose up`
