git clone https://github.com/EspeoBlockchain/gardener-smart-contracts.git

2. Copy smart contracts variables from template

cd gardener-smart-contracts
make copy-env

3. Copy server variables from template

cd ../gardener-server
make copy-env

4. Run test blockchain

make ganache
docker ps

5. Install smart contracts dependencies

cd ../gardener-smart-contracts
npm install

6. Migrate contracts to test blockchain

npx truffle migrate --network ganache --reset

7. Run server

cd ../gardener-server
make local

8. Make example oracle request

cd ../gardener-smart-contracts
npx truffle console --network ganache

truffle(ganache)> UsingOracle.deployed().then(instance => instance.request("json(https://api.coindesk.com/v1/bpi/currentprice.json).chartName"))
