 # NCD Risk Factor: Physical Inactivity
 
-The original intention of this repository is to provide a translation of the risk factor `NC_RFInactivity` from Spectrum.
-After this, the risk factor, and its interventions, can be modified as new releases of the model(s).
-
-## Data sources
-- TYPE_OF_DATA: FILEPATH_OF_EXCEL_WORKBOOK -> WORKSHEET_NAME
-- Prevalence: ./data/GBD_Country_Data.xlsx -> PIA_Guthold_2018
-- Relative Risks: ./data/RiskFactorData.xls -> RR
-- Impact Factors: ./data/RiskFactorData.xls -> ImpactFactors
-
-# Intervention Mapping
-## P1 Provide physical activity assessment, counselling, and behaviour change support as part of routine primary health care services through the use of a brief intervention
-- Brief advice as part of routine care 95%
-## P2 Implement sustained, population wide, best practice communication campaigns to promote physical activity, with links to community-based programmes and environmental improvements to enable and support behaviour change.
-- Awareness campaigns to encourage increased physical activity 95%
+## Overview
+
+This repository provides a translation of the risk factor `NC_RFInactivity` from Spectrum. It serves as a foundation for future modifications of the risk factor and its associated interventions as new model releases become available.
+
+## Data Components
+
+Risk Factors analysis requires three types of data:
+
+1. Prevalence
+2. Relative Risks
+3. Intervention Impacts (Impact Factors)
+
+### Data Sources
+
+| Data Type | File Path | Worksheet Name |
+|-----------|-----------|----------------|
+| Prevalence | `./data/GBD_Country_Data.xlsx` | PIA_Guthold_2018 |
+| Relative Risks | `./data/RiskFactorData.xls` | RR |
+| Impact Factors | `./data/RiskFactorData.xls` | ImpactFactors |
+
+### Accessing the Data
+
+The Spectrum data is available in the `data/` directory of this repository.
+
+For a computer-friendly version of this data:
+
+1. Clone this repository
+2. Run the `./extract_data.sh` script
+
+**Prerequisites:**
+- Bash shell
+- Python (accessible via `python` command)
+
+## Interventions
+
+### P1: Primary Care Integration
+
+**Intervention:** Provide physical activity assessment, counselling, and behaviour change support as part of routine primary health care services through the use of a brief intervention.
+
+**Implementation:**
+- Brief advice as part of routine care (95% coverage)
+
+### P2: Population-wide Communication Campaigns
+
+**Intervention:** Implement sustained, population-wide, best practice communication campaigns to promote physical activity, with links to community-based programmes and environmental improvements to enable and support behaviour change.
+
+**Implementation:**
+- Awareness campaigns to encourage increased physical activity (95% coverage)
