Integration of OpenMRS & DHIS2 for Patient Record

Dear All,
I am doing a project on my local instance on patient records and the
project is as follows:
I want a patient (John) who registered at facility A ( diagnostics
card, vitals, test result) should be automatically shared to facility
B and C where he went to further his treatments.

Firstly, this is my first time with openMRS but from the demo it shows
that it can capture everything that I needed as per patient report but
i will like to integrate the 2 systems (OpenMRS & DHIS2).

Please can someone with the following:
1. How can i install openMRS on my local system
2. How can i integrate the 2 systems to work effectively.
3. Is there away to achieve this implementation with only DHIS2?
