+# Starting the Dev Server
+The development server can be run by executing the `dev` file in the `bin` directory.
+```bash
+bin/dev
+```
+
+When running the development server for the first time, the postgres database will need to be created. You can do this by running `rails db:create` in the project directory.
+## Dependencies
+### Posgres
+```bash
+sudo apt install postgresql-all 
+```
+Then check if postgres is running with 
+```bash
+sudo systemctl status postgresql.service

+Note: ensure the user you are running postgres as has necessary permissions. They can be added with:
+```bash
+sudo su - postgres
+psql # enter postgres console
+ALTER USER my_user WITH Superuser;
+```
+Added permissions can be confirmed with `\du` within the psql console.
