+Generating leads with Odoo CRM
+==============================
+
+What is lead generation?
+========================
+
+Lead generation is the process by which a company acquires leads and
+collects relevant datas about potential customers in order to enable a
+relationship and to turn them into customers.
+
+For example, a website visitor who fills in your contact form to know
+more about your products and services becomes a lead for your company.
+Typically, a Customer Relationship Management tool such as Odoo CRM is
+used to centralize, track and manage leads.
+
+Why is lead generation important for my business?
+=================================================
+
+Generating a constant flow of high-quality leads is one of the most
+important responsibility of a marketing team. Actually, a well-managed
+lead generation process is like the fuel that will allow your company to
+deliver great performances - leads bring meetings, meetings bring sales,
+sales bring revenue and more work.
+
+How to generate leads with Odoo CRM?
+====================================
+
+Leads can be captured through many sources - marketing campaigns,
+exhibitions and trade shows, external databases, etc. The most common
+challenge is to successfully gather all the data and to track any lead
+activity. Storing leads information in a central place such as Odoo CRM
+will release you of these worries and will help you to better automate
+your lead generation process, share information with your teams and
+analyze your sales processes easily.
+
+Odoo CRM provides you with several methods to generate leads:
+
+* :doc:`../../leads/generate/from_emails`
+
+  An inquiry email sent to one of your company’s generic email addresses
+  can automatically generate a lead or an opportunity.
+
+* :doc:`../../leads/generate/manual`
+
+  You may want to follow up with a prospective customer met briefly at an
+  exhibition who gave you his business card. You can manually create a new
+  lead and enter all the needed information.
+
+* :doc:`../../leads/generate/website`
+
+  A website visitor who fills in a form automatically generates a lead or
+  an opportunity in Odoo CRM.
+
+* :doc:`../../leads/generate/import`
+
+  You can provide your salespeople lists of prospects - for example for a
+  cold emailing or a cold calling campaign - by importing them from any
+  CSV file.
