+# diddle
+
+Minimalist scheduling. A mobile friendly, fast, self-hosted Doodle alternative.
+
+## Installation
+
+The Diddle app is a traditional Flask web app that uses PostgreSQL for persistence. User settings are stored in HTTP cookies.
+
+Build a container image with `docker compose` (see `compose.yml`):
+
+    docker compose build
+
+or directly with `docker build`:
+
+    docker build -t diddle:latest .
+
+Deploy the image as you see fit.
+
+You can also run the app without containerization:
+
+    pip install -r requirements.txt # install pip dependencies
+    touch .env                      # put your env vars here
+    gunicorn --bind "0.0.0.0:8000" -w 4 app:app
+
