+# C#/.NET
+
+We target [.NET Standard 2.0](https://docs.microsoft.com/en-us/dotnet/standard/net-standard) so you can use .NET Framework 4.6.1+ or .NET Core 2.0+.  Simply add a reference to the [Spark Nuget package](https://nuget.org) to get started.
+
+```
+dotnet new console -lang c#
+dotnet add package spark_sdk
+dotnet build
+```
+
+# C++
+
+The easiest way to get started with C++ is to use the Spark Server SDK to develop your application.  Follow the instructions to [download and install the Spark Server SDK](/server/getting-started/install) and open the client_sdk sample project. If you want to run your C++ Client SDK application on Windows [contact us](mailto://api@bluetradesys.com) to get the required headers and binaries.
+
+# JavaScript
+
+We use JavaScript internally with the Spark Client API over a websocket connection but the documentation and packaging isn't ready yet.  If this is something you're interested in get in touch with us at [api@bluetradesys.com](mailto:api@bluetradesys.com).

+
+The Spark Client SDK is a high level command and control API which can be used to build scripts or integrate Spark into your existing ecosystem.  The API is divided into several independent **"services"** responsible for different aspects of the system.  A Service can define both [remote procedure call (RPC)](/client/getting-started/services#rpc) and incremental [streaming](/client/getting-started/services#streams) data.
+
+The [Spark Desktop](https://www.bluetradingsystems.com/bts-spark/) is built on top of this API so you can be assured that it is complete and well tested.
+
+Spark uses [Google Protocol Buffers](https://developers.google.com/protocol-buffers/) as an interface definition language similar to [GRPC](https://grpc.io) but backed by our custom high-performance TCP protocol.  We currently support C#/.NET and C++ <!--and Javascript--> but the architecture is designed for easy extension so contact us about your specific business needs.
+
+## Orders
+
+Use the [OrderService](/client/services/orderservice) to send and manage orders including native exchange orders, spreader orders, and custom Algo orders created using the [Spark Server SDK](https://api.bluetradesys.com/server/).
+
+## Spreader
+
+Use the [SyntheticSecurityService](/client/services/syntheticsecurityservice) to create and manage synthetic spreads.  Once created these spreads show up in the security and market data feeds just like exchange listed spreads.
+
+## Position
+
+Use the [PositionService](/client/services/positionservice) to get your position and P&L reports or add fills manually to keep the Spark system up to date with an external system.
+
+## Administration
+
+Use the [AdminService](/client/services/adminservice) to manage users and control limits.
+
+## Market Data
+
+For .NET subscribe to market data though the high level MarketDataClient interface.  From C++ or JavaScript use the MarketDataRelay service directly.

+
+The Spark Client SDK uses [Google Protocol Buffers](https://developers.google.com/protocol-buffers/) to define the interface for each service in a language independent manner.  Services have both functions which return a single result and streams of data which return values continuously while subscribed.  This page describes the mapping from the Protocol Buffer definition to the concrete definition in each supported language.
+
+# ServiceContext
+
+To connect your client to the Spark Server you need to get or create a `ServiceContext` instance.  A `ServiceContext` represents a connection to the Spark Server and a background thread for handling messages on that connection.  Generally there should be a single `ServiceContext` per process.  All of the methods on the `ServiceContext` are safe thread safe.
+
+Construct a ServiceContext by calling the default constructor.  The ServiceContext will find the Spark Server by loading the server configuration over an HTTP connection.  To determine the URL it will search the following locations and use the first one that is present.  
+
+* A command line argument `-configserver <url>`
+* An environment variable `BTSCONFIG`
+* `%APPDATA%/bts/conf/spark.conf` (Windows)
+* /sparkdata/conf/spark.conf (Linux)
+* $HOME/sparkdata/conf/spark.conf (Linux)
+
+If your application is running on a system with the BTS Client installed this will probably work without any further configuration.  If you plan to run your client application on a separate machine we recommend setting the `BTSCONFIG` environment variable.
+
+<div class="info">
+<i class="fa fa-lightbulb-o fa-fw" aria-hidden="true"></i>
+If you are using the Spark Server SDK to run a local copy of the Spark server set <p><strong>BTSCONFIG = http://localhost:9000/config/</strong></p>
+</div>
+
+To get a proxy for a given service call ServiceContext.locate&lt;T>("qualifier") where T is the type of the service and "qualifier" is an optional qualifier used to disambiguate between 2 instances of the same service.  The locate call cannot fail but it may return a disconnected proxy.  When you make a call on the proxy you should check the call result to see if the method call succeeded.
+
+# RPC
+
+Here is the OrderService reduced to a single method definition. A RPC method always takes exactly 1 argument and returns 1 value.  In this example the `create_order` call takes a `Create` instance and returns a `Response`.  
+
+```C
+service OrderService { 
+  rpc create_order(Create) returns (Response);
+  ...
+}
+```
+
+The `Create` and `Response` types are also defined as protocol buffer messages.  Each field can either be a primitive type another message or a list or map.
+
+```C
+message Create {
+  OrderDefinition new_order = 1;
+  double price = 2;
+  uint32 quantity = 3;
+}
+
+message Response {
+    uint32 order_key = 1; 
+    OrderError error_code = 2; 
+    string msg = 3;
+}
+```
+
+Each RPC call generates both synchronous (blocking) and asynchronous variants. In C# the asynchronous calls have the `_async` suffix and return a `Task`.  In C++ the call is overloaded to either return a value synchronously or accept a callback function to be called on the ServiceContext thread when the call completes. <!-- In Javascript only async methods returning a Promise are generated because it never makes sense to make a blocking call in the browser. -->
+
+To call the resulting service locate a proxy using the [ServiceContext](#servicecontext) and then call `cancel_order` or `cancel_order_async`.  If you are calling the Spark API from a GUI application you should always prefer the `_async` version of the calls.
+
+
+### C# example
+```c#
+var ctx = new ServiceContext();
+var orders = ctx.locate<OrderService>();
+var response = 
+  await orders.create_order_async(
+    new Create { price = 2.25, quantity = 42 });
+if (response.success) {
+  Console.WriteLine($"success: {response.value}");
+}
+else {
+  Console.WriteLine($"Error: {response.error_message}");
+}
+```
+### C++ example
+```cpp
+auto ctx = ServiceContext{};
+auto orders = ctx.locate<OrderService>();
+Create c;
+c.set_price(2.25);
+c.set_quantity(42);
+// Instead of providing an _async method C++ uses overloading.
+// To make a syncronous call simply omit the callback
+orders.create_order(c, [=](const Result<Response>& response) {
+  if(response.success()) {
+    std::cout << "success.";
+  }
+  else {
+    std::cout << "error: " << response.error_message();
+  }
+});
+```
+
+# Streams
+
+Streams allow you to subscribe to live updating data. Each stream represents a changing collection of protocol buffer objects.  Similar to a database row each item has an `id` which uniquely identifies it within the collection.  Updates from the Spark server can add, remove or replace entries in the collection.  Since only the changed items are sent over the wire the stream can remain responsive even when it represents a large collection.
+
+Streams are implemented using the language bindings for [ReativeX](http://reactivex.io/) which provide utility functions to drill down to the specific data your application needs. In C# we provide both mutable and immutable versions of the generated data types (C++ users can rely on `const`).
+
+When defined in a proto file streams use the `stream` keyword on the result type.
+```C
+service OrderService { 
+  ...
+  rpc fills (FillsSub) returns (stream Fill);
+}
+```
+
+### C# example
+```c#
+  var sc = new ServiceContext();
+  var orders = sc.locate<OrderService>();
+  var fills_observable = orders.subscribei_fills();
+  var unsub = fills_observable.Subscribe(update => {
+    Console.WriteLine(
+        "Added {0} items, Removed {1} items, Updated {2} items.  Total items {3}", 
+        update.added.Count(), 
+        update.removed.Count(), 
+        update.changes.Count(), 
+        update.all.Count());
+  });
+
+  Thread.Sleep(TimeSpan.FromMinutes(5));
+  unsub.Dispose();
+```
+### C++ Example

 ## I need to make a call that might take a few seconds. What is the best way to do this?

 Create a background thread in [do_before_launch](/server/ref/initialization#before-launch) or [do_launch](/server/ref/initialization#launch-launch-attached) to do the work.  Use [on_timer](/server/ref/subscriptions#timer) to poll until the result is available.
+
+## I don't see the header files in the .zip file. Where are they?
+
+The SDK headers are baked into the docker image along with the build tools. Once you've loaded the image with `docker load < spark_sdk.img` you can run this command to copy them out to your local file system `docker run --rm -it -v $PWD:/out spark_sdk /bin/tar -cvf /out/headers.tar /sdk/include`  This will copy the headers to the current directory in headers.tar.  We still recommend doing the actual build inside the docker environment but having a copy of the headers can be useful for setting up your development environment.
