Make sure you are on the correct path.
Step 1. Go to root directory, then run:
npm i
Step 2. Create .env file in root and copy-paste:
BLOCKFROST_APIKEY=#
CARDANO_NETWORK=0
AUTH_SERVER=https://auth-fuixlabs.ap.ngrok.io
CORS_DOMAINS="https://paperless-fuixlabs.ap.ngrok.io,https://resolver-fuixlabs.ap.ngrok.io"
MNEMONIC=#
CARDANO_NETWORK is 0 for Cardano Testnet, otherwise, 1 for Cardano Mainnet.
If you want to get MNEMONIC, go to https://iancoleman.io/bip39/ and choose 12 words to generate.
While the first runs, you will know your address on the console. To obtain 1000ADA, go to Faucet.
Step 3. Go to https://<localhost>/api-docs/ to read a document.
Run docker-compose up in cmd in root directory.
Make sure you are on the right path and the .env file has all the attributes described above.
