# Integration Guide This Integration Guide is intended for developers building on top of Wallet Core. Typical projects using Wallet Core are *mobile wallets* -- iOS and/or Android apps, and potentially desktop wallets. Wallet Core functionality can prove to be helpful in some backend-side projects as well. The guide has the following outline: * [Wallet Core Usage Guide](/developer/wallet-core/integration-guide/wallet-core-usage.md). In this general guide we describe the basic wallet operations (*wallet creation*, *address derivation*, *transaction signing*) in detail, with some code examples. This is recommended first. * [iOS Integration Guide](/developer/wallet-core/integration-guide/ios-guide.md). This is a walkthrough of a sample iOS wallet application. * [Android Integration Guide](/developer/wallet-core/integration-guide/android-guide.md). This is a walkthrough of a sample Android wallet application. * [Server-Side Go Guide](/developer/wallet-core/integration-guide/server-side.md). Here we provide instructions on how to integrate Wallet Core into a *Go* language backend-side project. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
