 You will also need to create 3 repositories in your organization:
 - **\<onboarding-repository-name\>**: This repository will be used for onboarding. It should contain the issue templates that will be used for onboarding.
 - **\<inventory-repository-name\>**: This repository will be used for inventory. It will contain the inventory metadata.
-- **\<policy-repository-name\>**: This repository will be used for the policies. It will contain the policies metadata.
+- **\<policy-repository-name\>**: This repository will be used for the policies. It will contain the policies metadata.

+# Running the application
+
+You will need a proxy such as [dev tunnels](https://learn.microsoft.com/en-us/azure/developer/dev-tunnels/get-started?tabs=windows) or something such as [Smee](https://smee.io) to route the requests from the GitHub platform to your computer<br/>
+
+To run the application locally, you can use the following command in the terminal:
+
+If you plan on using dev tunnels:
+
+Run the following once:
+```bash
+dotnet dev-certs https --trust
+```
+Then run the application with the HTTPS profile:
+```bash
+dotnet run --launch-profile https
+```
+
+If you plan on using a third-party proxy such as Smee, you will need to export the ASP.NET Core development certificate:
+
+Run the following once:
+```bash
+dotnet dev-certs https --trust --export-path /path/to/aspnetcoredevcert.pfx --password YourPassword --format pfx
+```
+Then run the application with the HTTPS profile:
+```bash
+dotnet run --launch-profile https
+```
+
+If you are using Smee, you will need to export your certificate to a CER file (a binary X.509 certificate)
+```bash
+openssl pkcs12 -in /path/to/aspnetcoredevcert.pfx -clcerts -nokeys -out /path/to/aspnetcoredevcert.cer
+```
+
+and use export it
+```bash
+export NODE_EXTRA_CA_CERTS=/path/to/aspnetcoredevcert.cer
+```
+
+or in PowerShell:
+```powershell
+$Env:NODE_EXTRA_CA_CERTS="/path/to/aspnetcoredevcert.cer"
+```
+
+The localhost endpoint for Smee to use will be `https://localhost:7135/api/github/webhook`
