 ## Project Overview
 
-The Explain Error Plugin is a Jenkins plugin that provides AI-powered explanations for build failures and pipeline errors. It integrates with multiple AI providers (OpenAI, Google Gemini, Ollama) to analyze error logs and provide human-readable insights to help developers understand and resolve build issues.

 ## Architecture
 
 ### Key Components
 
 - **GlobalConfigurationImpl**: Main plugin configuration class with `@Symbol("explainError")` for Configuration as Code support, handles migration from legacy enum-based configuration
 - **BaseAIProvider**: Abstract base class for AI provider implementations with nested `Assistant` interface and `BaseProviderDescriptor` for extensibility
-- **OpenAIProvider** / **GeminiProvider** / **OllamaProvider**: LangChain4j-based AI service implementations with provider-specific configurations
+- **OpenAIProvider** / **GeminiProvider** / **BedrockProvider** / **OllamaProvider**: LangChain4j-based AI service implementations with provider-specific configurations
 - **ExplainErrorStep**: Pipeline step implementation for `explainError()` function
 - **ConsoleExplainErrorAction**: Adds "Explain Error" button to console output for manual triggering
 - **ConsoleExplainErrorActionFactory**: TransientActionFactory that dynamically injects ConsoleExplainErrorAction into all runs (new and existing)

 ### Maven Configuration
 - Jenkins baseline: 2.479.3
 - Java 17+ required

 - Key Jenkins dependencies: `jackson2-api`, `workflow-step-api`, `commons-lang3-api`
 - SLF4J and Jackson exclusions to avoid conflicts with Jenkins core
 - Test dependencies: `workflow-cps`, `workflow-job`, `workflow-durable-task-step`, `workflow-basic-steps`, `test-harness`
