-Your content here...
+This guide walks you through building a complete application with iExec
+technology using DataProtector & IApp generator, from initial setup to live
+deployment.
+
+## Prerequisites
+
+- Node.js 20+ installed
+- Ethereum wallet
+- Docker installed & Docker Hub account
+
+## Step 1: Install iExec SDK and Tools
+
+```bash
+# Install iExec dependencies
+npm install @iexec/dataprotector @iexec/iapp
+
+```
+
+## Step 2: Set a front end
+
+You will need a front-end application to allow users to interact with your
+platform and use DataProtector to protect their data.
+
+To quickly bootstrap a Next.js project with DataProtector installed, use our
+starter template:
+[iExec Next.js Starter](https://github.com/iExecBlockchainComputing/iexec-nextjs-starter)
+
+This template is composed with a simple Next.js project with a form enabling the
+data protection through Dataprotector.
+
+This starter is set up with iExec network by default, but you can change the
+deployment chain.
+
+## Step 3: Build Your iExec Application (iApp)
+
+### 3.1 Check iApp Generator installation.
+
+Open your terminal and check if the iApp generator package is well installed on
+your environment by running the following command:
+
+```bash
+iapp --version
+```
+
+### 3.2 Init & Custom you iApp
+
+In order to compute protected data generated by DataProtector in a private and
+confidential TEE environment, you need to bootstrap and customize your
+application with iApp generator before deploying it on the selected chain.
+Please follow this guide:
+[iApp Generator](/references/iapp-generator/getting-started)
+
+### 3.3 Deploy your iApp
+
+Once your iApp is ready, you can deploy it on the selected chain by running the
+deploy command. Please follow this guide
+[Deploy an iApp](/guides/build-iapp/deploy-&-run)
+
+## Step 4: Manage access
+
+Once your DataProtector workflow is installed on your frontend and your iExec
+application is deployed, you can Manage Access. This means you need to authorize
+both a user and the iExec application to process the data using the Grant Access
+method. Please follow this guide
+[Manage Access](/guides/build-iapp/manage-access)
+

+- [Use iApps](/guides/use-iapp/)
+- [Advanced Features](/guides/build-iapp/advanced/)
+
+## Troubleshooting
+
+- **Connection Issues**: Ensure your wallet is connected to the correct network
+  (iExec mainnet)
+- **Gas Fees**: Make sure you have sufficient RLC for transactions
+- **TEE Execution**: Verify your application is compatible with Trusted
+  Execution Environments
+- **Data Access**: Check that your application has proper access to protected
+  datasets
