-Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/mars`. To experiment with that code, run `bin/console` for an interactive prompt.
+MARS (Multi-Agent Ruby SDK) provides a comprehensive framework for developers to implement multi-agent solutions using pure Ruby. It offers a simple, intuitive API for orchestrating multiple agents with support for sequential and parallel workflows, conditional branching, and visual workflow diagrams.
+
+## Features
+
+- 🤖 **Agent Orchestration**: Coordinate multiple agents with ease
+- 🔄 **Sequential Workflows**: Chain agents to execute tasks in order
+- ⚡ **Parallel Workflows**: Run multiple agents concurrently
+- 🚦 **Conditional Gates**: Branch workflows based on runtime conditions
+- 🔧 **Aggregators**: Combine results from parallel operations
+- 📊 **Visual Diagrams**: Generate Mermaid diagrams of your workflows
+- 🔌 **LLM Integration**: Built-in support for LLM agents via [ruby_llm](https://github.com/gbaptista/ruby_llm)
+- 🛠️ **Tools & Schemas**: Define custom tools and structured outputs for agents
+
+## Requirements
+
+- Ruby >= 3.1.0
 
 ## Installation
 
-TODO: Replace `UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG` with your gem name right after releasing it to RubyGems.org. Please do not do it earlier due to security reasons. Alternatively, replace this section with instructions to install your gem from git if you don't plan to release to RubyGems.org.
+Add this line to your application's Gemfile:
 
-Install the gem and add to the application's Gemfile by executing:
+```ruby
+gem 'mars_rb'
+```
+
+And then execute:
 
 ```bash
-bundle add UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG
+bundle install
 ```
 
-If bundler is not being used to manage dependencies, install the gem by executing:
+Or install it yourself as:
 
 ```bash
-gem install UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG
+gem install mars_rb
+```
+
+## Quick Start
+
+Here's a simple example to get you started:
+
+```ruby
+require 'mars'
+
+# Create agents
+agent1 = Mars::Agent.new(name: "Agent 1")
+agent2 = Mars::Agent.new(name: "Agent 2")
+agent3 = Mars::Agent.new(name: "Agent 3")
+
+# Create a sequential workflow
+workflow = Mars::Workflows::Sequential.new(
+  "My First Workflow",
+  steps: [agent1, agent2, agent3]
+)
+
+# Run the workflow
+result = workflow.run("Your input here")
+```
+
+## Core Concepts
+
+### Agents
+
+Agents are the basic building blocks of MARS. They represent individual units of work:
+
+```ruby
+agent = Mars::Agent.new(
+  name: "My Agent",
+  instructions: "You are a helpful assistant",
+  options: { model: "gpt-4o" }
+)
+```
+
+### Sequential Workflows
+
+Execute agents one after another, passing outputs as inputs:
+
+```ruby
+sequential = Mars::Workflows::Sequential.new(
+  "Sequential Pipeline",
+  steps: [agent1, agent2, agent3]
+)
+```
+
+### Parallel Workflows
+
+Run multiple agents concurrently and aggregate their results:
+
+```ruby
+aggregator = Mars::Aggregator.new(
+  "Results Aggregator",
+  operation: lambda { |results| results.join(", ") }
+)
+
+parallel = Mars::Workflows::Parallel.new(
+  "Parallel Pipeline",
+  steps: [agent1, agent2, agent3],
+  aggregator: aggregator
+)
 ```
 
-## Usage
+### Gates
 
-TODO: Write usage instructions here
+Create conditional branching in your workflows:
+
+```ruby
+gate = Mars::Gate.new(
+  name: "Decision Gate",
+  condition: ->(input) { input[:score] > 0.5 ? :success : :failure },
+  branches: {
+    success: success_workflow,
+    failure: failure_workflow
+  }
+)
+```
+
+### Visualization
+
+Generate Mermaid diagrams to visualize your workflows:
+
+```ruby
+diagram = Mars::Rendering::Mermaid.new(workflow).render
+File.write("workflow_diagram.md", diagram)
+```
+
+## Examples
+
+Check out the [examples](examples/) directory for more detailed examples:
+
+- [Simple Workflow](examples/simple_workflow/) - Basic sequential workflow with gates
+- [Parallel Workflow](examples/parallel_workflow/) - Concurrent agent execution
+- [Complex Workflow](examples/complex_workflow/) - Nested workflows with multiple gates
+- [Complex LLM Workflow](examples/complex_llm_workflow/) - Real-world LLM integration with tools and schemas
 
 ## Development
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
 
 To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org).
 
+## Testing
+
+Run the test suite with:
+
+```bash
+bundle exec rake spec
+```
+
