Dependency `redis` left out

[JordanPlayz158]

Describe the bug In the documentation, you give a list and example of all required dependencies but forgot redis which causes composer install --no-dev --optimize-autoloader and subsequent commands to fail

To Reproduce Steps to reproduce the behavior:

1. Follow the current documentation guide up to "Depdendency installation" (might want to also fix the spelling mistake)
2. Run the first command in that section and you will get the Connection refused [tcp://localhost:6379] error

Expected behavior The command resolves fine saying the expected message of Package manifest generated successfully.
