     * Last-contact-time mapping
     * Address as single field (plus code? lat/long? go crazy!)
     * Free-text-entry field
+    * Desired contact periodicity
 * Journal with Obsidian-like `[[link]]` syntax
+* Contact groups (e.g. "Met with `[[Brunch Bunch]]` at the diner")
 * ical server for birthday reminders

 ## Planned features
 * Report birthdays and manage add'l fields for contacts stored on a remote CardDAV server
 * Act as CardDAV server for other clients
 * For each contact:
     * Arbitrary add'l yearly dates (e.g. anniversaries) that show on calendar
     * Relationship mapping
-    * Desired contact periodicity
     * Additional arbitrary fields (no special handling)
-* Contact groups (e.g. "Met with `[[Brunch Bunch]]` at the diner")
 * "Named in journal but has no contact entry" detection
 * Email birthday reminders over SMTP

+## Development / self-hosting
+
+1. Clone the repo.
+2. Build for your system with `./Taskfile _cargo build --release`.
+3. Deploy the binary from `./target/release/mascarpone` to wherever you want that's accessible to you.
+4. In the working directory that you want the server to save its databases in,
+    1. Create a user for yourself with `mascarpone set-password YOUR_USERNAME`. This will create a `users.db` file.
+    2. Run `mkdir dbs`.
+    3. Copy the `hashed_static` directory from the code repository.
+5. Run `mascarpone serve [port]` from that working directory. The default port is 3000.
+   If you need to be able to bind to a host other than `0.0.0.0`, contact me directly.
