 ## Overview
 
-Orion Software Developer Kit is a set of functions and methods that allow dApp developers connect to the superior aggregated liquidity of Orion Protocol which combines orderbooks of centralized exchanges as well decentralized automatic market makers such as Uniswap or Spookyswap across several supported blockchains.
-Through this connection, developers using the SDK can perform a wide range of actions, including swapping selected tokens using Orion’s aggregated liquidity, obtaining relevant market information through subscriptions, add and remove liquidity to Orion’s pools.
+Lumia Stream Developer Kit, natively built into Lumia, is a set of functions and methods that allow dApp developers to connect to the superior aggregated liquidity of Lumia Stream which combines orderbooks of centralized exchanges as well as decentralized Automatic Market Makers (AMMs) such as Uniswap, PancakeSwap, and Curve, across several supported blockchains. Through this connection, developers using the SDK can perform a wide range of actions, including swapping selected tokens, obtaining relevant market information through subscriptions, and more.
 
 ## API Key
 
-Orion’s SDK is free to use and does not require an API key or registration. Refer to integration examples for more detailed information.
