Just a heads up, the Crypti Dapp docs on GitHub are outdated, or simply aren't correct. I tried to set up an environment on Linux (Ubuntu 15.04) following this tutorial to the tee : https://github.com/crypti/crypti-dapps-docs/blob/master/EnvironmentSetup.md, but was unable to. The Testnet Client simply doesn't install properly, with the current instructions.
