8-13: Consider enhancing the introduction with more context.While the introduction provides good prerequisite information, it could be improved by:
- Briefly explaining what local-da is and its benefits
- Specifying the version of local-da being used
Consider expanding the introduction like this:
-This tutorial serves as a comprehensive guide for using the [local-da](https://github.com/rollkit/local-da) with your chain. +This tutorial serves as a comprehensive guide for using [local-da](https://github.com/rollkit/local-da) - a lightweight, local Data Availability (DA) layer implementation perfect for testing and development. This allows you to develop and test your chain without connecting to production DA networks.
28-52: Enhance running instructions with more context.The running instructions could be improved by:
- Explaining the differences between Quick Start and Wordle Chain configurations
- Using a more generic timestamp in the log example
Consider these improvements:
## Run your rollup -Start your rollup node with the following command, ensuring to include the DA address flag: +Start your rollup node with one of the following commands, depending on your setup: ::: code-group ```sh [Quick Start] +# Basic configuration for testing rollkit start --rollkit.da_address http://localhost:7980+# Advanced configuration with aggregator and custom rollup ID rollkit start \ --rollkit.aggregator \ --rollkit.da_address http://localhost:7980 \ --rollkit.sequencer_rollup_id wordle:::
You should see the following log message indicating that your rollup is connected to the local DA network:
-I[2024-11-15|14:54:19.842] DA server is already running module=main address=http://localhost:7980 +I[<timestamp>] DA server is already running module=main address=http://localhost:7980--- `53-55`: **Enhance summary with next steps and troubleshooting.** The summary could be more helpful by including: 1.

92-102: Consider enhancing namespace generation guidanceWhile the OpenSSL command for namespace generation is helpful, consider adding:
- A note about namespace uniqueness importance
- An example of what the final namespace should look like after replacement

89-93: Fix the localhost URL schemeThe URL
https://localhost:8000is using HTTPS which is unlikely for a local development setup.

117-120: Improve the gas price section integrationThe gas price information box seems abruptly placed. Consider:
- Moving it to the configuration section
- Expanding on the relationship between DA network gas prices and rollup gas prices
- Adding examples of typical gas price configurations
Warning message needs more context and alternative path
The tutorial appears to be actively maintained and contains detailed instructions, but the warning message should be enhanced since:
- The tutorial contains complete implementation steps and recent references (e.g., Turing testnet)
- The content seems well-structured and comprehensive
- Other files in the repository use warning blocks effectively with more context
Suggested improvements for the warning message:
- Specify which parts of the tutorial are broken (e.g., specific commands, configurations)
- Add a temporary workaround if available (e.g., using local development setup)
- Include the last known working version/configuration
- Link to the documentation for alternative DA solutions mentioned in the repository

4-8: Consider adding more context to the warning messageWhile it's good to warn users about the broken tutorial, consider:
- Specifying which parts are broken
- Adding an estimated timeline for the fix
- Providing alternative approaches if available
This helps users make an informed decision about whether to proceed.

1-7: LGTM! File setup follows VitePress best practices.
The setup properly handles markdown linting exceptions and imports constants for version management.
14-23: Security considerations for installation and network configuration.
The current installation method and network configuration have several security considerations:
- The curl | bash pattern can be unsafe without checksum verification
- The exposed port 7980 might need firewall configuration
Consider:
- Adding SHA256 checksum verification
- Adding firewall configuration guidance
- Warning about running in production environments
Example improvement:
To set up a local DA network node on your machine, run the following script to install and start the local DA node:
+
+> ⚠️ Warning: This installation method is intended for development environments only. For production deployments, please follow security best practices and verify checksums.
+
```bash-vue
curl -sSL https://rollkit.dev/install-local-da.sh | bash -s {{constants.localDALatestTag}}-This script will build and run the node, which will then listen on port 7980.
+This script will build and run the node, which will then listen on port 7980. Ensure this port is only accessible locally if you're running in a shared environment:

The import path has been updated to use a relative path. Let's verify this path exists and is correct.
✅ Verification successful
Let me try another approach to verify the constants import path.
Since the file .vitepress/constants/constants.js exists at the exact path referenced in the import statement ../../.vitepress/constants/constants.js, the import path is correct.
Import path is valid ✅
The relative import path ../../.vitepress/constants/constants.js correctly resolves to the existing constants file from the location of tutorials/da/celestia-da.md.
