+# West Wood Club for Home Assistant
+
+A [Home Assistant](https://www.home-assistant.io/) integration that exposes the
+**live member count** of [West Wood Club](https://westwood.ie/) gyms as sensors.
+
+The West Wood app is a white-label build of **PerfectGym Go**, so this integration
+talks to PerfectGym's backend (`https://goapi2.perfectgym.com`). The API was
+reverse-engineered from a capture of the app's traffic; see [`api.md`](api.md) for
+the documented endpoints.
+
+## Features
+
+- One occupancy sensor per club, reporting the number of members currently checked
+  in (`GET /v1/Clubs/WhoIsInCount`).
+- All selected clubs are grouped under a single **West Wood Club** device.
+- `measurement` state class, so Home Assistant records long-term statistics and
+  history graphs per club.
+- A single poll per update interval feeds every sensor.
+
+## Getting a token
+
+Authentication is a long-lived bearer token. Generate one with `get-token.py`
+(stdlib only — needs no dependencies):
+
+```bash
+WESTWOOD_EMAIL=you@example.com WESTWOOD_PASSWORD=... python get-token.py
+```
+
+It prints the token to stdout (credentials can also be entered interactively).
+
+## Installation
+
+### NixOS (flake)
+
+This repo's flake exposes the integration as a package and an overlay. Add it as a
+flake input on your Home Assistant host, apply the overlay, and list it in
+`customComponents`:
+
+```nix
+# flake inputs
+inputs.hass-west-wood.url = "git+ssh://git@git.nul.ie/dev/hass-west-wood.git";
+
+# NixOS module
+{ pkgs, ... }:
+{
+  nixpkgs.overlays = [ inputs.hass-west-wood.overlays.default ];
+
+  services.home-assistant = {
+    enable = true;
+    extraComponents = [ "default_config" ];
+    customComponents = [ pkgs.home-assistant-custom-components.west_wood_club ];
+  };
+}
+```
+
+### Manual
+
+Copy `custom_components/west_wood_club/` into your Home Assistant `config/custom_components/`
+directory and restart Home Assistant.
+
+## Configuration
+
+The integration is configured through the UI:
+
+1. **Settings → Devices & Services → Add Integration → West Wood Club**.
+2. Paste a bearer token (from `get-token.py`).
+3. Select the clubs to create sensors for.
+
+If the token is later rejected, Home Assistant starts a reauth flow to paste a
+fresh one.
+
+## Development
+
+See [`AGENTS.md`](AGENTS.md) for the dev environment (Nix flake + nix-direnv),
+code style, and working with the traffic capture.
