+## Documentation
+
+### Platforms
+
+`trust-wallet-core` only supports `macOS/OSX` at the moment. `Linux` and `Windows` support is forthcoming.
+
+### Bindings
+
+-   This project uses [`node-addon-api`](https://github.com/nodejs/node-addon-api) to interface with `wallet-core` [C headers]((https://github.com/TrustWallet/wallet-core/tree/master/include/TrustWalletCore)). 
+-   The `node-addon-api` functions are wrapped in TypeScript that is then used to generate a JavaScript module with type definitions.
+
+### Memory management
+
+-   Please note that memory allocated with C/C++ is released once there are no references to the JavaScript object, then Node.js garbage collector will try to release it from memory.
+
+## Other Resources
+
+-   For general [`TrustWallet/wallet-core`](https://github.com/TrustWallet/wallet-core) documentation, please refer to [GitBooks](https://developer.trustwallet.com/wallet-core).
