Things which I've followed and would recommend: - Have a vagrant box set up so that the new engineer doesn't have to waste his/her time setting up the system. Use Ansible/Chef/puppet for provisioning the vagrant box. Saves at least a day. - Make sure all the git repos have a good README file explaining the project details. - If you have an API powering your backend, use http://swagger.io/ http://swagger.io/ or something similar, so that other engineers don't have to waste time explaining all the API endpoints. - Maintain an internal wiki or a Google Sites which lists all the common problems faced earlier. You can also explain the business logic and the general flow of the application here.
