 # snibox-sqlite
 
 Snibox container working with SQLite3 database for personal use
+
+To run this container use following parameters:
+
+```bash
+docker run -d --name snibox \
+              --volume /path/to/local/db:/app/db/database \
+              --env SECRET_KEY_BASE="<rails secret key>" \
+              --publish 80:3000 \
+              snibox
+```
+
+After first run you probably will see error due to database hasn't been initialized in the attached volume. Pleas run following command to create empty database:
+
+```bash
+docker exec -ti <container_id> rack db:migrate
+```
+
+This will create new database instance and Snibox is ready to go.
