 # Project Plan: Roesticoin - A Stablecoin on the Ethereum Blockchain
 
 
+## Getting all running
+when switching between Devcontainer and production, rebuild the container, because the base image is different
+### For development in Devcontainer
+- open in VS Code
+- add and modify `.env` file based on `.env.sample`
+- reopen in container
+### As release in Production
+- add and modify `.env` file based on `.env.sample`
+- `docker-compose -f docker-compose.yml -f docker-compose.release.yml up --build -d`
+
 
 ## Project Title:  
 **Roesticoin: Swiss Franc-Pegged Stablecoin on Ethereum**
