+
+### setup pipenv
+
+when working on the fastapi backend, you want to be using the
+`/backend/Pipfile` with `pipenv`
+
+avoid trouble by setting up these two environment variable before using `pipenv`
+
+```
+# tell pipenv to use the /backend/Pipfile
+export PIPENV_PIPFILE=$(pwd)/Pipfile
+
+# tell pipenv to create and use the .venv directory for virtual environment
+# in this directory here
+export PIPENV_VENV_IN_PROJECT=1
+```
+
+## run api in dev mode
+
+```
+pipenv run fastapi dev
+```
+
+## Docker
+
+build the image locally
+```
+docker build -t pastebin-backend .
+```
+
+run the container
+```
+docker run -p 8000:8000 pastebin-backend
+```
