+# How to run container
+
+### Build
+In the root directory of project there is `Dockerfile` in which image is defined.
+<br> Build the image:
+```bash
+docker build -t listhub:1.0 .
+```
+Then after building the image you can run it. You will need to define some environment variables.
+```bash
+docker run -d \
+--name listhub_backend \
+-p 8080:8080 \
+-e JWT_SECRET=<paste_your_secret_here> \
+-e DB_URL=jdbc:postgresql://db:5432/postgres \
+-e DB_USER=postgres \
+-e DB_PASS=postgres \
+listhub_backend:1.0
+```
+
+or you can use compose file with .env file
+
+```text
+// .env
+JWT_SECRET=<paste_your_secret_here>
+
+DB_URL=jdbc:postgresql://db:5432/postgres
+DB_USER=listhub
+DB_PASS=postgres
+```
