-TECH STACK
-
-- Haskell and Scotty backend
-- HTMX frontend
-- SQLite database
-
-GOALS
-
-- Generate sufficiently memorable but secure passwords for use with accounts

+# purr
+
+[purr.eversole.co](https://purr.eversole.co)
+
+a simple web application offering customizable password generation 
+and time-limited sharing of secrets.
+
+## TECH STACK
+
+- [Haskell](https://www.haskell.org)
+- [Scotty](https://hackage.haskell.org/package/scotty)
+- [HTMX](https://htmx.org)
+- [SQLite](https://www.sqlite.org)
+
+## GOALS
+
+- Provide a minimal and clean interface for generating and sharing passwords.
+- Generate sufficiently memorable but secure passwords for use with accounts 
+that don't offer better authentication methods.
+- Share text secrets with others without disclosing the secret in the 
+message itself.
+- Maintain a clean and organized codebase that can be extended to include more
+utilities than originally anticipated.
+
+## WHY TRUST PURR.EVERSOLE.CO?
+
+You shouldn't. This is free and open-source software which you can run on your 
+own hardware!
+
+## DEPLOYMENT
+
+Only Nix build instructions are provided below.
+
+### No Containers
+1) Clone this repository
+2) Build the application (with flakes enabled): `nix build '.#'`
+3) Set the environment variables
+    - File: `cp examples/.env.example ./.env; $EDITOR ./.env`
+    - If you want to set them in a different way, you already know how.
+4) Run the application: `./result/bin/Purr`
+
+### Containers
+1) Clone this repository
+2) Build the container image (with flakes enabled): `nix build .#purr-container`
+3) Load the container image: `podman load -i result`
+4) Pick option 5, 6, or use your favorite process to manage containers and ENV
+5) NixOS configuration:
+```
+virtualisation.oci-containers.containers.purr = {
+  image = "purr";
+  ports = [ "${PURR_EXTERNAL_PORT}:3000" ];
+  volumes = [
+    "/PATH/TO/PURR/data:/app/data"
+  ];
+  environment = { 
+    PURRNOFILE = "true";
+    ENVIRONMENT = "production";
+    APPLICATIONHOST = "localhost";
+    APPLICATIONPORT = "3000";
+    DATADIR = "/app/";
+    LINKLENGTH = "24";
+    ADMINEMAIL = "${YOUR_EMAIL}";
+  };
+};
+```
+6) Docker Stack
+    1) Copy the docker-stack.yml example and edit as needed.
+        1) `cp examples/docker-stack.yml ./; $EDITOR ./docker-stack.yml`
+    2) Set environment variables:
+        - `cp examples/.env.example ./.env; $EDITOR ./.env`
+        - Or set them in the docker-stack.yml environment declaration.
+    3) Deploy: `docker stack deploy -c docker-stack.yml purr`
+
+## DEVELOPMENT & SUPPORT
+
+Per the permissive ISC license, you are free to do what you wish with this
+software. No guarantees are made to its usability, security, or functionality.
