Hi @Suheb,
As a starting point, I would recommend this resource: Set up your HubSpot account
After that, the free CRM course would be good for all stakeholders: https://academy.hubspot.com/courses/set-up-your-hubspot-crm-for-growth
After that, the steps really depend on the type of business, products/services, digital proficiency, and prospects/customers. If you want to share more context, I can elaborate.
Best regards
