 ## Development
 
 Make sure `rake ethereum:test:setup` passes before running tests. 
 
 You can also run `bin/console` for an interactive prompt that will allow you to experiment.
-Then, run `rake spec` to run the tests. Test that do send transactions to blockchain are marked with `blockchain` tag. To run first fast tests that use no ether and slow test that do spend ether run the following line:
 
-    $ sudo bin/install_parity

+Test that do send transactions to blockchain are marked with `blockchain` tag. Good practice is to run first fast tests that use no ether and only if they pass, run slow tests that do spend ether. To do that  use the following line:
+
+    $ bundle exec rspec --tag ~blockchain && bundle exec rspec --tag blockchain
 
 You need ethereum node up and running for tests to pass and it needs to be working on testnet (Ropsten).
