-# Action-carbon-emission-calculator-Demo
+# Carbon Emission Calculator AllSpice Actions Demo
+This is repository with an Altium-based design for demonstrating the "Carbon Emission Calculator" AllSpice Actions add-on.

-A repository for demonstrating the "Carbon Emission Calculator" AllSpice Actions add-on.
+This action uses the [generate-bom](https://hub.allspice.io/Actions/generate-bom) and [carbon-emission-calculator](https://hub.allspice.io/Actions/carbon-emission-calculator) Actions add-ons publically available in the [AllSpice Hub Actions](https://hub.allspice.io/Actions) organization.
+
+As shown and explained below in the YML workflow file, the generate-bom add-on is used to generate a BOM using the py-allspice BOM generation utility function, and the carbon-emission-calculator add-on is used to obtain mock carbon emission data for the Archimajor 3D printer BOM components from a repository-based data source.
+
+## Usage
+
+### Step 1) Modify emission data ingestion in the add-on to your need:
+
+The carbon-emission-calculator add-on uses a standalone data source CSV file with mock emissions figures for each component in the Archimajor 3D printer PCBA BOM. For your specific use, you will need to provide a data source and modify the data ingestion or query from source to match your needs:
+
+#### For CSV-based data sources:
+
+Replace your data source URL with the mock data URL in the add-on. The file format assumes part number as the 1st column, and the emission figure as the second column:
+```
+ALLSPICE_DEMO_CARBON_EMISSION_DATA_URL = "https://hub.allspice.io/AllSpice-Demos/Demo-Data-Source/raw/branch/main/Carbon-Emissions-Figures-Archimajor/archimajor-carbon-emissions-figures.csv"
+```
+
+#### For Database-based data sources:
+
+If your emissions data is stored in a database, you will need a service to present that data via a queryable API endpoint. A rudimentary example of querying an API endpoint for emissions data is shown below:
+
+```
+ALLSPICE_DEMO_CARBON_EMISSION_DATA_API_URL_BASE = "https://your.site"
+ALLSPICE_DEMO_CARBON_EMISSION_DATA_PART_SEARCH_ENDPOINT = ALLSPICE_DEMO_CARBON_EMISSION_DATA_API_URL_BASE + "/get_emission_figure/"
+
+################################################################################
+def query_demo_carbon_emission_data_for_mfr_part_number(url):
+    # Post the request and get the response
+    response = requests.get(url)
+    # Populate the search result return value
+    part_search_response = response.text
+    # Return response status code and search result
+    return (response.status_code, part_search_response)
+```
+
+### Step 2) Add the following step to your actions:
+
+```yaml
+# AllSpice running carbon emission calculator demo workflow
+# Action triggers on push and issues
+# Action runs "carbon-emission-calculator" action
+# .allspice/workflows/Carbon-Emission-Calculator.yml
