 ## Backend Starter
 
-Follow these steps to start up Postgres database:
+- Please open the VS Code Command Palette
+- Run the command **Dev Containers: Rebuild and Reopen in Container**
+- This should open the dev container with the same file directory mounted so any changes in the dev container will be seen in the local repo
 
-Make sure you have Docker installed!
+### In Dev Container
 
+Run this to reset the database and populate it with the approprate tables that reflect the entities folder
+```
+python3 -m backend.script.reset_demo
 ```
 
-\\ Spins up local postgres database and pgadmin
-docker-compose up -d
+### Possible Dev Container Errors
 
-\\ Stop and teardown containers
-docker-compose down
-
-\\ Stop and teardown containers + volumes (full reset)
-docker-compose down -v
-```
+- Sometimes the ports allocated to our services will be allocated (5432 for Postgres and 5050 for PgAdmin4)
+- Run **docker stop** to stop all containers
+- If that does not work using **sudo lsof -i :[PORT_NUMBER]** to find the process running on the needed ports and idenitfy the PID
+- Run **sudo kill [PID]**
+- If you are on Windows please consult ChatGPT or set up WSL (will be very useful in the future)
