invalid task names in readme

[masukomi]

in the readme the task names are all parallel:foo but the reality is that you need to use app:foo

not sure which is desired in the current version but they should both be the same. ;)

expected behavior:

expected to be able to run rake parallel:spec

actual behavior

had to run rake app:parallel:spec

notes

here's the output of rake --tasks

❯ rake --tasks | grep parallel

[grosser]

they should not be under app:
check how the tasks are required and compare it against the readme
