 # OpenWeatherMap-gRPC-Server
 
-Microservice that accepts remote procedure calls to fetch weather data
\ No newline at end of file
+A microservice that accepts remote procedure calls to fetch weather data.
+
+The service uses [protocol buffers](https://developers.google.com/protocol-buffers/docs/overview)
+to define a [gRPC API](https://grpc.io/docs/what-is-grpc/introduction/) that
+fetches current and extended weather data. 
+
+Weather data is obtained from [OpenWeather's](https://openweathermap.org/api)
+high-end servers.
+
+## Sending Requests
+
+### Basic Workflow
+
+1. Generate the necessary code for your preferred language from the files in
+the proto directory with the protoc compiler
+2. Import the code into your project
+3. Use the imported code to allow your client to connect with the server
+4. Use the imported code within your own functions to make requests
+
+#### Generating code from the .proto files
+
+Run protoc from the root of the project. The below example shows how one might
+generate Go code.
+
+```
+protoc -Iproto --go_opt=module=codeberg.org/andcscott/OpenWeatherMap-gRPC-API \
+--go_out=. --go-grpc_opt=module=codeberg.org/andcscott/OpenWeatherMap-gRPC-API \
+--go-grpc_out=. proto/*.proto
+```
+
+#### Importing the code
+
+Import the code into your project. Example in Go:
+
+```
+import pb "codeberg.org/andcscott/OpenWeatherMap-gRPC-API/proto"
+```
+
+#### Using the imported code to connect to the server
+
+First, enable your client to connect to the server. Example in Go:
+
+```
+conn, err := grpc.Dial("localhost:5000", grpc.WithTransportCredentials(insecure.NewCredentials()))
+if err != nil {
+	log.Fatalln(err)
+}
+defer conn.Close()
+
+c := pb.NewWeatherServiceClient(conn)
+```
+
+See the [test-client](test-client/main.go) for more details.
+
+#### Using the imported code to make requests
+
+In this case, we're requesting the current weather for Corvallis, OR.
+
+```
+func doCurrent(c pb.WeatherServiceClient) {
+	res, err := c.Current(context.Background(), &pb.RequestCurrent{
+		City: "Corvallis",
+	})
+	if err != nil {
+		log.Fatalln(err)
+	}
+	log.Println(res.Payload)
+}
+```
+
+See the [test-client](test-client/current.go) for more details.
+
+## Receiving the response
+
+Data will be sent to your client as JSON. Example from the above call:
+
+```
+{"coord":{"lon":-123.262,"lat":44.5646},"weather":[{"id":800,"main":"Clear","description":"clear sky","icon":"01n"}],"base":"stations","main":{"temp":296.87,"feels_like":297.13,"temp_min":294.98,"temp_max":298.62,"pressure":1007,"humidity":70},"visibility":10000,"wind":{"speed":2.14,"deg":284,"gust":1.94},"clouds":{"all":0},"dt":1658811503,"sys":{"type":2,"id":2005452,"country":"US","sunrise":1658753522,"sunset":1658807208},"timezone":-25200,"id":5720727,"name":"Corvallis","cod":200}
+```
