 To build on a 32-bit Raspbian GNU/Linux 11 on 64-bit hardware, the OpenSSL library must be manually configured. This is due to the OpenSSL autoconfiguration script detecting 64-bit hardware and emitting 64-bit ARM assembly instructions which are not allowed in 32-bit executables. A 32-bit ARM version of OpenSSL can be configured by setting 32-bit ARM platform:
 `cmake .. -DBUILD_OPENSSL_PLATFORM=linux-armv4`
 
-### Threadpool for the SDK
-The threadpool is enabled by default, and starts with 3 threads that it can increase up to 10 if all are actively in use. To change these values to better match the resources of your use case you can set the environment variables to do so:
-1. `export AWS_KVS_WEBRTC_THREADPOOL_MIN_THREADS=<value>`
-2. `export AWS_KVS_WEBRTC_THREADPOOL_MAX_THREADS=<value>`
+### KVS Threadpool
+Starting version 1.10.0, threadpool usage provides latency improvements in connection establishment. Note that increasing the number of minimum threads can increase stack memory usage. So, ensure to increase with caution.

 ### Set up TWCC
 TWCC is a mechanism in WebRTC designed to enhance the performance and reliability of real-time communication over the Internet. TWCC addresses the challenges of network congestion by providing detailed feedback on the transport of packets across the network, enabling adaptive bitrate control and optimization of
