If you're a user, all you have to do is head over to the Remix IDE and locate the Starknet Remix Plugin in the plugins section. Want to make it even simpler? Click right through to Remix using [this direct link](https://remix.ethereum.org/#activate=Starknet) and you're good to go! 🎉
	2. **Usage**: Once the plugin is activated, you'll find a user-friendly interface that allows you to deploy and interact with Starknet contracts. Follow the on-screen prompts and tooltips for an effortlessly smooth experience!
	3. **Feedback**: Your feedback is invaluable to us 🌟! If you encounter any issues or have game-changing suggestions, don't hesitate to reach out through our [Discord](https://discord.com/invite/PaCMRFdvWT) or our [Community Forum](https://community.nethermind.io/). Let's make something awesome together! 🤝
	### Troubleshooting
	Most issues with Starknet plugin or Remix itself are caused by connectivity problems (also resulting from restricted networks, web-proxies blocking certain content, etc.) or browser plugin interference.
	- A user should first attempt to disable any browser components & addons which may impact the connectivity or Javascript execution.
	- Some networks may restrict connectivity to certain sites or domains. Using a VPN connection may resolve problems observed on restricted networks.
	More specific potential error causes are also described in detail below.
	<details>
	<summary><strong>1. Problems when searching plugins in Remix UI</strong></summary>
	<br/>
	Searching for online plugins in Remix IDE may return blank or otherwise incorrect content, such as on screenshot below:
	
	Ensure that the following URL is accessible from a web browser, and that a JSON metadata code is returned -
	https://raw.githubusercontent.com/ethereum/remix-plugins-directory/master/build/metadata.json :
	
	</details>
	<details>
	<summary><strong>2. Problems when launching Starknet plugin in Remix UI</strong></summary>
	<br/>
	Starknet plugin launch issues may be caused by connectivity errors or plugin components being unavailable. This can be tested from web browser, as indicated below:
	- https://cairo-remix-test.nethermind.io should respond with blank page (advanced: viewing page source will reveal a React component entry HTML markup) - no errors should be reported by the browser
	- https://cairo-compile-remix-test.nethermind.io/health should respond with `OK`
	- https://starknet-devnet-dev.nethermind.io/predeployed_accounts should respond with JSON text describing predeployed Starknet accounts
	</details>
	<details>
	<summary><strong>3. `localStorage` access errors</strong></summary>
	<br/>
	The following error indicates that the browser is blocking access to `localStorage` element of the webpage:
	
	Possible causes:
	- Chrome is launched in incognito mode
	- Chrome setting "Block third-party cookies" is activated (see [chrome://settings/cookies](chrome://settings/cookies)):
	
	Note: even with "Block third-party cookies" activate, exceptions can be added to a whitelist - the whitelist must include:
	- https://remix.ethereum.org
	- https://cairo-remix-test.nethermind.io
	- ...also see this [link](https://stackoverflow.com/questions/30481516/iframe-in-chrome-error-failed-to-read-localstorage-from-window-access-deni) for potential hints.
	</details>
	## For Developers
	### Installation
	#### API
	Our API is built with [Rocket](https://rocket.rs/), a web framework for Rust. So, you'll need to get Rust and Cargo on your machine to get started. 🛠️
	The easiest way to install Rust and Cargo is by using [rustup](https://rustup.rs/). It's the [recommended tool](https://www.rust-lang.org/tools/install) for managing Rust versions and associated tools for your project.
	Then:
	```bash
	cd api;
	git submodule update --init;
	cargo build;
	```
	#### Plugin
	The plugin it self is a React project, you'll need to install [pnpm](https://pnpm.io/installation#using-npm).
	```bash
	cd plugin;
	pnpm install;
	```
	#### Running the development environment
	You need to be running both the server and the plugin in order to have a working environment.
	For your dev environment:
	```bash
	cd plugin;
	pnpm run start;
	```
	For an optimized build (will not listen to changes):
	```
	pnpm run deploy;
	pnpm run serve;
	```
	```bash
	cd api;
	cargo run;
	```
	or alternatively, you can run the server in watch mode (with `cargo watch`):
	```bash
	cargo install cargo-watch;
	cargo watch -x run;
	```
	For devnet interactions, you'll need to use [Starknet Devnet](https://github.com/Shard-Labs/Starknet-devnet).
	##### Connecting the plugin
	In [Remix](http://remix-alpha.ethereum.org/), go to the `Plugin Manager` at the bottom of the left panel, and click on `Connect to a Local Plugin`.
	Then, chose a name for the plugin, and in the `URL` field, enter `http://localhost:3000`, the `Type of Connection` should `iframe` and the `Location in remix` `Side Panel` and click on `Ok`, see the image below.
	
	You should be all set to see the magic happen! Activate the plugin and it should now be visible and ready to be hacked with! 🚀

Step 2: ⌨️ Coding

• Modify plugin/src/components/DevnetAccountSelector/index.tsx ✓ 7296dc8

Modify plugin/src/components/DevnetAccountSelector/index.tsx with contents:
• Replace the `is_alive` endpoint with the `version` endpoint in the `checkDevnetUrl` function. This involves changing the URL in the fetch request from `${devnet.url}/is_alive` to `${devnet.url}/version`.
• Update the condition in the if statement that checks the status of the response. Instead of checking if `status !== 'Alive!!!'`, it should check if the response does not contain a version number. This can be done by parsing the response as JSON and checking if the `version` property exists.

Step 3: 🔁 Code Review

Here are my self-reviews of my changes at sweep/local-katana-integration.

Here is the 1st review

The changes made in the file "plugin/src/components/DevnetAccountSelector/index.tsx" are correct and well implemented. Good job on that!

However, the changes for the file "plugin/src/components/EnvironmentSelector/index.tsx" were not provided in the diff. Please ensure that similar changes are made in this file as well, specifically:

• Replace the is_alive endpoint with the version endpoint in the handleEnvironmentChange function. This involves changing the URL in the fetch request from ${devnet.url}/is_alive to ${devnet.url}/version.
• Update the condition in the if statement that checks the status of the response. Instead of checking if status !== 'Alive!!!', it should check if the response does not contain a version number. This can be done by parsing the response as JSON and checking if the version property exists.

Once these changes are made and provided, we can proceed with the review.

I finished incorporating these changes.
