-purr is intended to run in a docker container. 
+Use Nix with flakes enabled.
-This repo's Stack project is configured to use a musl-based docker container for builds. 
-Assuming your working directory is inside of this repository:
 
-1. Copy "examples/config.dhall" to ./config.dhall - configure this file appropriately.
+Build binary and run natively:
-  - Use `openssl rand -hex 10` to generate an encryption key for "dbKey"
+nix build && ./result/bin/Purr-musl
-2. Copy "examples/Dockerfile" to ./Dockerfile
+
-3. If using default database file location, run: `mkdir ./data; touch ./data/Purr.sqlite`
+Build and add Docker image to local registry:
-4. Run `chmod +x build-docker`
+nix build .#purrImage --impure && docker load < result
-5. Run `./build-docker $IMAGE_NAME` to complete the initial Stack build and create the container
-6. Orchestrate the container as desired
-  - docker run -d -v "$(pwd -P)/data/Purr.sqlite:/app/data/Purr.sqlite" \
-    -v "$(pwd -P)/config.dhall:/app/config.dhall" \
-    -p 5195:3000 purr
- |- An example docker-stack.yml is provided: `docker stack deploy -c docker-stack.yml purr`
