 # weatherapi
 
-A small HTTP API that serves a variety of weather-related endpoints.
+`weatherapi` is a small HTTP API that serves weather data backed by the
+PostgreSQL schema populated by `weatherfeeder`.
+
+## Config
+
+`weatherapi` reads a YAML config file that is either:
+- a top-level list of database entries, or
+- an object with `databases:`.
+
+Example:
+
+```yaml
+- name: weatherdb
+  driver: postgres
+  params:
+    uri: postgres://weatherdb:5432/weatherdb?sslmode=disable
+    username: weatherdb
+    password: weatherdb
+```
+
+## Endpoints
+
+- `GET /conditions/current`
+- `GET /observations?count=<1..100>&units=<us|metric>`
+- `GET /forecast?timestamp=<RFC3339 timestamp>`
+- `GET /alerts/current`
+
+Default unit behavior:
+- `/conditions/current`: US units
+- `/observations`: metric units
+- `/forecast`: US units
+
+`/conditions/current`, `/observations`, and `/forecast` support `?units=us|metric`.
+`/observations` defaults to `count=5` and validates `count` strictly in range `1..100`.
+
+## Run
+
+```bash
+go run ./cmd/weatherapi -config ./config.yml -addr :8080
+```
