 # DevBox Landing Page
 
 Git repository for frontend and backend for the DevBox landing page and email collection service.
+
+## Development Setup
+
+### Set up development environment with Python venv
+
+We use pythons built in module, venv, to create an isolated python environment.
+
+[Python Documentation for virtual environments][0]
+
+#### Initialize the virtual environment
+
+The following command initializes the virtual environment in the `.venv/`-dirctory
+
+```shell
+python3 -m venv .venv
+```
+
+Then you use one of the following commands to activate the virtual environment in your current shell session
+
+##### Bash
+
+```shell
+source .venv/bin/activate
+```
+
+##### Fish
+
+```shell
+source .venv/bin/activate.fish
+```
+
+##### Install python modules
+
+Now you can install the python modules for this project with the following command
+
+```shell
+pip3 install -r requirements.txt
+```
+
+##### Add a new module to requirements.txt
+
+Run the following commands to install a new module and add it to the `requirements.txt`-file.
+
+In this example we install the `SQLAlchemy`-module.
+
+```shell
+pip3 install SQLAlchemy
+python3 -m pip freeze > requirements.txt
+```
+
+##### Upgrade pip3 modules
+
+###### List outdated modules
+
+```shell
+pip3 list --outdated
+```
+
+###### Upgrade all outdated modules
+
+```shell
+pip3 list -o | cut -f1 -d' ' | tr " " "\n" | awk '{if(NR>=3)print}' | cut -d' ' -f1 | xargs -n1 pip3 install -U
+```
+
+###### Save changes to requirements.txt
+
+```shell
+python3 -m pip freeze > requirements.txt
+```
+
+### Building and running with Docker or Podman
+
+#### Docker
+
+```shell
+docker build -t devbox-back:latest .
+docker run --rm -it -p "8000:8000" -v './db:/usr/src/app/db' devbox-back:latest
+```
+
+#### Podman
+
+```shell
+podman build -t devbox-back:latest .
+podman run --rm -it -p "8000:8000" -v './db:/usr/src/app/db' devbox-back:latest
+```
