Bug: docs(connector): Add wasm docs in connector integration docs



Add connector.md file doesn't have information about connector configs where we add connector to control center from backend configs. Documentation for where to add configs in wasm should be mentioned in add_connector.md

+### **Connector configs for control center**
+
+This section is explicitly for developers who are using the [Hyperswitch Control Center](https://github.com/juspay/hyperswitch-control-center). Below is a more detailed documentation that guides you through updating the connector configuration in the `development.toml` file in Hyperswitch and running the wasm-pack build command. Please replace placeholders such as `/absolute/path/to/` with the actual absolute paths.
+
+1. Install wasm-pack: Run the following command to install wasm-pack:
+
+```bash 
+cargo install wasm-pack
+```
+
+2. Add connector configuration:
+
+   Open the `development.toml` file located at `crates/connector_configs/toml/development.toml` in your Hyperswitch project.
+
+   Locate the [stripe] section as an example and add the configuration for the `example_connector`. Here's an example:
+
+   ```toml
+   # crates/connector_configs/toml/development.toml
+
+   # Other connector configurations...
+
+   [stripe]
+   [stripe.connector_auth.HeaderKey]
+   api_key="Secret Key"
+
+   # Add any other Stripe-specific configuration here
+
+   [example_connector]
+   # Your specific connector configuration for reference
+   # ...
+
+   ```
+
+   provide the necessary configuration details for the `example_connector`. Don't forget to save the file.
+
+3. Update paths:
+
+   Replace `/absolute/path/to/hyperswitch-control-center` with the absolute path to your Hyperswitch Control Center repository and `/absolute/path/to/hyperswitch` with the absolute path to your Hyperswitch repository.
+
+4. Run `wasm-pack` build:
+
+   Execute the following command in your terminal:
+
+   ```bash
+   wasm-pack build --target web --out-dir /absolute/path/to/hyperswitch-control-center/public/hyperswitch/wasm --out-name euclid /absolute/path/to/hyperswitch/crates/euclid_wasm -- --features dummy_connector
+   ```
+
+   This command builds the WebAssembly files for the `dummy_connector` feature and places them in the specified directory.
+
+Notes:
+
+- Ensure that you replace placeholders like `/absolute/path/to/` with the actual absolute paths in your file system.
+- Verify that your connector configurations in `development.toml` are correct and saved before running the `wasm-pack` command.
+- Check for any error messages during the build process and resolve them accordingly.
+
+By following these steps, you should be able to update the connector configuration and build the WebAssembly files successfully.
+
+Certainly! Below is a detailed documentation guide on updating the `ConnectorTypes.res` and `ConnectorUtils.res` files in your [Hyperswitch Control Center](https://github.com/juspay/hyperswitch-control-center) project.
+
+Update `ConnectorTypes.res`:
+
+1. Open `ConnectorTypes.res`:
+
+   Open the `ConnectorTypes.res` file located at `src/screens/HyperSwitch/Connectors/ConnectorTypes.res` in your Hyperswitch-Control-Center project.
+
+2. Add Connector enum:
+
+   Add the new connector name enum under the `type connectorName` section. Here's an example:
+
+   ```reason
+   /* src/screens/HyperSwitch/Connectors/ConnectorTypes.res */
+
+   type connectorName =
+     | Stripe
+     | DummyConnector
+     | YourNewConnector
+     /* Add any other connector enums as needed */
+   ```
+
+   Replace `YourNewConnector` with the name of your newly added connector.
+
+3. Save the file:
+
+   Save the changes made to `ConnectorTypes.res`.
+
+Update `ConnectorUtils.res`:
+
+1. Open `ConnectorUtils.res`:
+
+   Open the `ConnectorUtils.res` file located at `src/screens/HyperSwitch/Connectors/ConnectorUtils.res` in your [Hyperswitch Control Center](https://github.com/juspay/hyperswitch-control-center) project.
+
+2. Add Connector Description:
+
+   Update the following functions in `ConnectorUtils.res`:
+
+   ```reason
+   /* src/screens/HyperSwitch/Connectors/ConnectorUtils.res */
+
+
+   let connectorList : array<connectorName> = [Stripe,YourNewConnector]
+
+
+   let getConnectorNameString = (connectorName: connectorName) =>
+     switch connectorName {
+     | Stripe => "Stripe"
+     | DummyConnector => "Dummy Connector"
+     | YourNewConnector => "Your New Connector"
+     /* Add cases for other connectors */
+     };
+
+   let getConnectorNameTypeFromString = (str: string) =>
+     switch str {
+     | "Stripe" => Stripe
+     | "Dummy Connector" => DummyConnector
+     | "Your New Connector" => YourNewConnector
+     /* Add cases for other connectors */
+     };
+
+   let getConnectorInfo = (connectorName: connectorName) =>
+     switch connectorName {
+     | Stripe => "Stripe connector description."
+     | DummyConnector => "Dummy Connector description."
+     | YourNewConnector => "Your New Connector description."
+     /* Add descriptions for other connectors */
+     };
+
+   let getDisplayNameForConnectors = (connectorName: connectorName) =>
+     switch connectorName {
+     | Stripe => "Stripe"
+     | DummyConnector => "Dummy Connector"
+     | YourNewConnector => "Your New Connector"
+     /* Add display names for other connectors */
+     };
+   ```
+
+   Adjust the strings and descriptions according to your actual connector names and descriptions.
+
+
+4. Save the File:
+
+   Save the changes made to `ConnectorUtils.res`.
+
+Notes:
+
+- Ensure that you replace placeholders like `YourNewConnector` with the actual names of your connectors.
+- Verify that your connector enums and descriptions are correctly updated.
+- Save the files after making the changes.
+
+By following these steps, you should be able to update the `ConnectorTypes.res` and `ConnectorUtils.res` files with the new connector enum and its related information.
+
+
+
+Certainly! Below is a detailed documentation guide on how to add a new connector icon under the `public/hyperswitch/Gateway` folder in your Hyperswitch-Control-Center project.
+
+Add Connector icon:
+
+1. Prepare the icon:
+
+   Prepare your connector icon in SVG format. Ensure that the icon is named in uppercase, following the convention. For example, name it `YOURCONNECTOR.SVG`.
+
+2. Open file explorer:
+
+   Open your file explorer and navigate to the `public/hyperswitch/Gateway` folder in your Hyperswitch-Control-Center project.
+
+3. Add Icon file:
+
+   Copy and paste your SVG icon file (e.g., `YOURCONNECTOR.SVG`) into the `Gateway` folder.
+
+4. Verify file structure:
+
+   Ensure that the file structure in the `Gateway` folder follows the uppercase convention. For example:
+
+   ```
+   public
+   └── hyperswitch
+       └── Gateway
+           └── YOURCONNECTOR.SVG
+   ```
+    Save the changes made to the `Gateway` folder.
+
+
 ### **Test the connector**
 
 The template code script generates a test file for the connector, containing 20 sanity tests. We anticipate that you will implement these tests when adding a new connector.
