We believe that the best way to learn how to build a DApp on the Telos blockchain is to be guided step-by-step to build something tangible that can be observed by other users. For that reason we are going to start off with a minimal interaction with the Telos blockchain, followed by building a simple to-do list application.
Generate keys either using
cleos command line wallet or another tool (api.telos.net is another option)
Use the Testnet Faucet to create an account and get some testnet TLOS
Import those keys into your wallet of choice, and write them down somewhere you will not lose them!
