+# S3 Encryption Client Examples
+
+This directory contains example projects for the Amazon S3 Encryption Client across different programming languages and major versions.
+
+## Directory Structure
+
+Each language has subdirectories for different major versions of the S3 Encryption Client:
+
+- `cpp/` - C++ examples
+  - `v2/` - S3EC C++ v2 example (transitional)
+  - `v3/` - S3EC C++ v3 example (improved)
+- `dotnet/` - .NET examples
+  - `v3/` - S3EC .NET v3 example (transitional)
+  - `v4/` - S3EC .NET v4 example (improved)
+- `go/` - Go examples
+  - `v3/` - S3EC Go v3 example (transitional)
+  - `v4/` - S3EC Go v4 example (improved)
+- `java/` - Java examples
+  - `v3/` - S3EC Java v3 example (transitional)
+  - `v4/` - S3EC Java v4 example (improved)
+- `php/` - PHP examples
+  - `v2/` - S3EC PHP v2 example (transitional)
+  - `v3/` - S3EC PHP v3 example (improved)
+- `ruby/` - Ruby examples
+  - `v2/` - S3EC Ruby v2 example (transitional)
+  - `v3/` - S3EC Ruby v3 example (improved)
+
+## Setup Instructions
+
+### Prerequisites
+
+1. **Git Submodules**: Some examples depend on staging versions of the S3EC libraries that are included as git submodules. Initialize and update submodules:
+
+   ```bash
+   git submodule update --init --recursive
+   ```
+
+2. **AWS Credentials**: Configure your AWS credentials using one of the following methods:
+   - AWS CLI: `aws configure`
+   - Environment variables: `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`
+   - IAM roles (for EC2 instances)
+
+3. **KMS Key**: Use "arn:aws:kms:us-east-2:648638458147:key/a47079da-17e4-45a5-b82e-2bac101cad01" by default, or create a KMS key in your AWS account and note the key ID for use in examples.
+
+### Language-Specific Setup
+
+Each language directory contains specific setup instructions in its README file. Generally:
+
+- **Java**: Requires JDK 11+ and Gradle
+- **Go**: Requires Go 1.21+
+- **.NET**: Requires .NET 8.0+
+- **PHP**: Requires PHP 7.4+ and Composer
+- **Ruby**: Requires Ruby 3.0+ and Bundler
+- **C++**: Requires CMake 3.16+ and C++17 compiler
+
+## Usage
+
+Each example directory contains:
+
+- Build configuration files (e.g., `build.gradle.kts`, `go.mod`, `composer.json`)
+- Source code demonstrating basic S3EC usage
+- README with specific setup and run instructions
+
+## Dependencies
+
+Examples use different dependency sources based on version:
+
+- **Released versions**: Use public package repositories (Maven Central, npm, etc.)
+- **Staging versions**: Use git submodules pointing to staging repositories
+- **Local versions**: Reference locally built libraries
+
+## Support
+
+For issues with specific examples, refer to the individual README files in each language/version directory.
