# Country Implementation

## Overview

This is a guide to implement MOSIP for a country. It is advised that Government and System Integrators (SI) study the recommended steps to work out an appropriate implementation strategy. The items are in "near-chronological order" and may differ for an implementation.

## Key decisions

1. Choice of deployment of [Pre-registration](/1.2.0/~/changes/EDXkAXJ2BnUpKbwo76Y3/id-lifecycle-management.md#pre-registration).
2. Rate of enrolment desired.
3. Rate of authentication expected.
4. [Languages](/1.2.0/~/changes/EDXkAXJ2BnUpKbwo76Y3/modules/module-configuration.md#languages).
5. Customisation and procurement of components as given [here](/1.2.0/~/changes/EDXkAXJ2BnUpKbwo76Y3/modules/reference-implementations.md).
6. [ID schema](/1.2.0/~/changes/EDXkAXJ2BnUpKbwo76Y3/id-lifecycle-management/id-schema.md) (as prescribed by the country's regulatory authority).
7. Hardware requirements estimate.

   * [Devices](https://github.com/mosip/documentation/blob/1.2.0/docs/_files/mosip-devices-calculator.xlsx)
8. [Credential choices](/1.2.0/~/changes/EDXkAXJ2BnUpKbwo76Y3/modules/id-repository.md#credential-types).
9. ID Card print design.
10. MOSIP versions.
11. MOSIP support (scope).
12. Disaster recovery strategy.
13. Phased approach for rollout.

## Procurement

1. Engagement with an SI - terms and conditions.
2. Procurement of biometric and other external components.
3. HSM
4. [Postgres](https://docs.mosip.io/1.2.0/modules/persistence/postgres-db))
5. [Object store](https://docs.mosip.io/1.2.0/modules/persistence/object-store)
6. Compute hardware

## Country specific data

1. [Masterdata](https://docs.mosip.io/1.2.0/modules/administration/masterdata-guide)
2. [Applicanttype MVEL](https://github.com/mosip/mosip-config/blob/develop3-v3/applicanttype.mvel)

## Customisation

1. Customisation of components as decided in [step 5 of Key decisions](#key-decisions) above.

## Deployment

1. [Certifcate/key generation](/1.2.0/~/changes/EDXkAXJ2BnUpKbwo76Y3/modules/keymanager/keys.md)
2. [Deployment design](https://docs.mosip.io/1.2.0/deploymentnew/getting-started).
3. Disaster recover set up
4. Biometric thresholding
5. Phased implementation
6. [Sandbox](https://docs.mosip.io/1.2.0/sandbox-details), staging, development setups.
7. IDA installation

## Partners

1. Onboarding of trusted partners
2. Print partner

## Rollout

1. Set up of registration centers
2. Onboarding of officers and supervisors
3. Training

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.mosip.io/1.2.0/~/changes/EDXkAXJ2BnUpKbwo76Y3/country-implementation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
