+# Flow Sample 1
+
+A basic example project showcasing various Genkit flows.
+
+## Project Setup
+
+### Installation
+
+Ensure you have `pnpm` installed and run the following:
+
+```bash
+pnpm install
+```
+
+### Build and Run
+
+To build and run the project, use:
+
+```bash
+pnpm build-and-run
+```
+
+This compiles the TypeScript source code and runs the `index.js` file in the `lib` directory.
+
+---
+
+## Available Flows
+
+### Basic Flow
+
+A simple flow that demonstrates the use of `run`.
+
+#### Command:
+
+```bash
+genkit flow:run basic '"test input"'
+```
+
+#### Expected Output:
+
+```text
+"foo: subject: test input"
+```
+
+---
+
+### Parent Flow
+
+A flow that runs the `basic` flow and returns its output as a JSON string.
+
+#### Command:
+
+```bash
+genkit flow:run parent
+```
+
+#### Expected Output:
+
+```text
+"\"foo: subject: foo\""
+```
+
+---
+
+### Streamy Flow
+
+A streaming flow that emits incremental data based on the input number.
+
+#### Command:
+
+```bash
+genkit flow:run streamy 5
+```
+
+#### Expected Output:
+
+```text
+done: 5, streamed: 5 times
+```
+
+The streamed content will also show intermediate outputs for each count.
+
+---
+
+### StreamyThrowy Flow
+
+Similar to `streamy`, but throws an error when the count reaches 3.
+
+#### Command:
+
+```bash
+genkit flow:run streamyThrowy 5
+```
+
+#### Expected Output:
+
+Throws an error at count 3.
+
+---
+
+### Throwy Flow
+
+Demonstrates error handling by throwing an error when a subject is provided.
+
+#### Command:
+
+```bash
+genkit flow:run throwy '"test input"'
+```
+
+#### Expected Output:
+
+Throws an error with the message:
+
+```text
+test input
+```
+
+---
+
+### Throwy2 Flow
+
+Throws an error within the `run` function based on input.
+
+#### Command:
+
+```bash
+genkit flow:run throwy2 '"test input"'
+```
+
+#### Expected Output:
+
+Throws an error with the message:
+
+```text
+test input
+```
+
+---
+
+### FlowMultiStepCaughtError
+
+A multi-step flow that catches errors and continues execution.
+
+#### Command:
+
+```bash
+genkit flow:run flowMultiStepCaughtError '"input data"'
+```
+
+#### Expected Output:
+
+```text
+"input data, Step 1, , Step 3"
+```
+
+A string indicating that Step 2 had an error, but the process continued.
+
+---
+
+### MultiSteps Flow
+
+A flow demonstrating chaining multiple steps.
+
+#### Command:
+
+```bash
+genkit flow:run multiSteps '"sample input"'
+```
+
+#### Expected Output:
+
+```text
+42
+```
+
+---
+
+### LargeSteps Flow
+
+Processes large chunks of data across multiple steps.
+
+#### Command:
+
+```bash
+genkit flow:run largeSteps
+```
+
+#### Expected Output:
+
+```text
+"Finished processing large data."
+```
+
+---
+
+## Running the Developer UI
+
+To visualize flows in the Developer UI, start the server:
+
+```bash
+genkit start
+```
+
+Open your browser and navigate to `http://localhost:4000`.
+
+---
+
+## Notes
