 To get started with the SKALE Portal, users can visit the [SKALE Portal](https://portal.skale.space/) website and click on the "Connect wallet" button. Users can then connect their wallets and select the source and destination blockchains for their transfers.
 
 ## Development Setup
+
 If you're interested in contributing to the SKALE Portal, follow these steps to set up your development environment:
 
 1. Clone the repository: `git clone --recurse-submodules https://github.com/skalenetwork/portal.git`
-2. Install dependencies: `cd portal && yarn install`
-3. Prepare metadata: `NETWORK_NAME=[SKALE NETWORK NAME - mainnet or staging] bash build.sh`
-4. Export Mainnet Ethereum endpoint to your env: `export VITE_MAINNET_ENDPOINT=XXX` or create `.env` file in the root dir
-5. Start the development server: `yarn start`
+2. Install dependencies: `cd portal && bun i`
+3. Build the project:
+
+- Mainnet env: `bun build:mainnet`
+- Testnet env: `bun build:testnet`
+
+4. Start the development server: `VITE_WC_PROJECT_ID=[PUT WALLETCONNECT PROJECT ID HERE] bun dev`
 
 The SKALE Portal is built using the Create React App TypeScript template and uses [Metaport](https://github.com/skalenetwork/metaport) and [ima-js](https://github.com/skalenetwork/ima-js) libraries.
