+# Development Mode
+
+Development Mode in flyscrape allows you to streamline the process of creating and fine-tuning your scraping scripts. With the `flyscrape dev` command, you can watch your scraping script for changes and see the results in real-time, making it easier to iterate and perfect your data extraction process during development.
+
+## The `flyscrape dev` Command
+
+The `flyscrape dev` command is a powerful tool that enhances your development workflow by automating the execution of your scraping script when changes are detected. This feature is incredibly useful for several reasons:
+
+1. **Immediate Feedback**: With Development Mode, you can make changes to your scraping script and instantly see the impact of those changes. There's no need to manually run the script after each modification.
+
+2. **Efficiency**: It eliminates the need to repeatedly run the `flyscrape run` command while you fine-tune your scraping logic. This boosts your efficiency and accelerates development.
+
+3. **Real-time Debugging**: If you encounter issues or unexpected behavior in your scraping script, you can quickly identify and fix problems with real-time feedback.
+
+## Using the `flyscrape dev` Command
+
+To activate Development Mode, use the `flyscrape dev` command followed by the name of your scraping script. For example:
+
+```bash
+flyscrape dev my_scraping_script.js
+```
+
+This command will start watching your scraping script file (`my_scraping_script.js` in this case) for changes. Whenever you save changes to the script, flyscrape will automatically re-run it, allowing you to view the updated results in your terminal.
+
+## Tips for Development Mode
+
+Here are some tips to make the most of Development Mode:
+
+1. **Keep Your Editor Open**: Keep your code editor open and edit your scraping script as needed. When you save the changes, flyscrape will automatically pick them up.
+
+2. **Console Output**: Use `console.log()` statements within your scraping script to output debugging information to the console. This can be helpful for diagnosing issues.
+
+3. **Iterate and Experiment**: Take advantage of Development Mode to experiment with different data extraction queries and strategies. The rapid feedback loop makes it easy to iterate and find the right approach.
+
+## Example Workflow
+
+Here's an example of how a typical workflow might look in Development Mode:
+
+1. Create a new scraping script using `flyscrape new`.
+
+2. Use `flyscrape dev` to start watching the script.
+
+3. Edit the script, add data extraction logic, and save the changes.
+
+4. Observe the results in real-time in the terminal.
+
+5. If needed, make further changes and continue iterating until you achieve the desired data extraction results.
+
+Development Mode is an invaluable tool for scraping script development, enabling you to build and refine your scripts efficiently and effectively.
+

+
+This concludes the "Development Mode" section, which demonstrates how to use the `flyscrape dev` command to streamline your scraping script development process. Next, you can explore how to initiate scraping with the "Start scraping" section to gather data from websites.

+# Scraping Setup
+
+In this section, we'll delve into the details of setting up your scraping script using the `flyscrape new script.js` command. This command is designed to streamline the process of creating a scraping script, providing you with a structured starting point for your web scraping endeavors.
+
+## The `flyscrape new` Command
+
+The `flyscrape new` command allows you to generate a new scraping script with a predefined structure and sample code. This is incredibly helpful because it provides a quick and easy way to begin your web scraping project.
+
+## Creating a New Scraping Script
+
+To create a new scraping script, use the `flyscrape new` command followed by the desired script filename. For example:
+
+```bash
+flyscrape new my_scraping_script.js
+```
+
+This command will generate a file named `my_scraping_script.js` in the current directory. You can then open and edit this file with your preferred code editor.
+
+## Script Overview
+
+Let's take a closer look at the structure and components of the generated scraping script:
+
+```javascript
+import { parse } from 'flyscrape';
+
+export const options = {
+ url: 'https://example.com/', // Specify the URL to start scraping from.
+ depth: 1, // Specify how deep links should be followed. (default = 0, no follow)
+ allowedDomains: [], // Specify the allowed domains. ['*'] for all. (default = domain from url)
+ blockedDomains: [], // Specify the blocked domains. (default = none)
+ allowedURLs: [], // Specify the allowed URLs as regex. (default = all allowed)
+ blockedURLs: [], // Specify the blocked URLs as regex. (default = non-blocked)
+ proxy: '', // Specify the HTTP(S) proxy to use. (default = no proxy)
+ rate: 100 // Specify the rate in requests per second. (default = 100)
+};
+
+export default function ({ html, url }) {
+ const $ = parse(html);
+
+ // Your data extraction logic goes here
+
+ return {
+ // Return the structured data you've extracted
+ };
+}
+```
+
+## Implementing the Data Extraction Logic
+
+In the generated scraping script, you'll find the comment "// Your data extraction logic goes here." This is the section where you should implement your custom data extraction logic. You can use tools like [Cheerio](https://cheerio.js.org/) or other libraries to navigate and extract data from the parsed HTML.
+
+Here's an example of how you might replace the comment with data extraction code:
+
+```javascript
+// Your data extraction logic goes here
+const title = $('h1').text();
+const description = $('p').text();
+
+// You can extract more data as needed
+```
+
+## Returning the Extracted Data
+
+After implementing your data extraction logic, you should structure the data you've extracted and return it from the scraping function. The comment "// Return the structured data you've extracted" is where you should place this code.
+
+Here's an example of how you might return the extracted data:
+
+```javascript
+return {
+ title: title,
+ description: description
+ // Add more fields as needed
+};
+```
+
+With this setup, you can effectively scrape and structure data from web pages to meet your specific requirements.
+
+---
+
+This concludes the "Scraping Setup" section, which provides insights into creating scraping scripts using the `flyscrape new` command, implementing data extraction logic, and returning extracted data. Next, you can explore more advanced topics in the "Development Mode" section to streamline your web scraping workflow.

+# Start Scraping
+
+In this section, we'll dive into the process of initiating web scraping using flyscrape. Now that you have created and fine-tuned your scraping script, it's time to run it and start gathering data from websites.
+
+## The `flyscrape run` Command
+
+The `flyscrape run` command is used to execute your scraping script and retrieve data from the specified website. This command is your gateway to turning your scraping logic into actionable results.
+
+## Running Your Scraping Script
+
+To run your scraping script, simply use the `flyscrape run` command followed by the name of your script file. For example:
+
+```bash
+flyscrape run my_scraping_script.js
+```
+
+This command will initiate the scraping process as defined in your script. Flyscrape will execute your script and stream the JSON output of the extracted data directly to your terminal.
+
+## Saving Scraped Data to a File
+
+You can easily save the JSON output of the scraped data to a file using standard shell redirection. For example, to save the scraped data to a file named `result.json`, you can use the following command:
+
+```bash
+flyscrape run my_scraping_script.js > result.json
+```
+
+This command will execute your scraping script and save the extracted data in the `result.json` file in the current directory.
+
+## Example Workflow
+
+Here's a simple workflow for starting web scraping with flyscrape, including saving the scraped data to a file:
+
+1. Create a scraping script using `flyscrape new` and fine-tune it using `flyscrape dev`.
+
+2. Save your script.
+
+3. Run the script using `flyscrape run`.
+
+4. Observe the terminal as flyscrape streams the JSON output of the extracted data in real-time.
+
+5. If you want to save the data to a file, use redirection as shown above (`flyscrape run my_scraping_script.js > result.json`).
+
+6. Customize the script to store, process, or further analyze the extracted data as needed.
+
+7. Continue scraping or iterate on your script for more complex scenarios.
+
+With this workflow, you can efficiently gather and process data from websites using flyscrape, with the option to save the extracted data to a file for later use or analysis.
