-Spice SDK is a flat C, header-only library that can be included in your DLL.
+Spice SDK is a flat C, header-only library that can be included in your hook DLL.
 
 Once initialized, you can call directly into helper routines provided by Spicetools executable, making low-latency and high-throughput interactions possible.
+
+## Instructions
+
+#### Include header files
+Grab the latest SDK header files from the `-full` release package. Look inside `spice2x\extras\sdk\include`.
+
+There are currently two files - `sdkspice.h` and `spicesdk_io.h`. First one is mandatory and must be included in your project; second one is only needed if you need named enum types for buttons/analogs/lights.
+
+#### Add `spice_sdk_entry_point` dllexport
+
+See one of the `.def` files in the sample section for an example.
+
+#### Implement `spice_sdk_entry_point` in your project
+
+Sample C++ code:
+
+```cpp
+
+spice_sdk_destroy_callback_func destroy_callback;
+
+SPICE_SDK_ENTRY_POINT
+spice_sdk_entry_point(
+    spice_sdk_init_func *init
+)
+{
+    SPICE_SDK_STATUS_CODE status;
+
+    spice.size = sizeof(spice);
+    status = init(0, destroy_callback, &spice);
+    if (status != SPICE_SDK_STATUS_SUCCESS) {
+        return 0;
+    }
+
+    // spin up a worker thread here
+    return 1;
+}
+
+void
+__cdecl
+destroy_callback(
+    void
+)
+{
+    // unload
+}
+
+```
+
+#### Compile & run
+Compile the DLL, and add to spice as a DLL hook (using `-k` parameter).
+
+It currently doesn't work as an early hook.
