 How to create a contact into Odoo CRM?
 ======================================
+
+Odoo CRM allows you to manually add contacts into your pipeline. It can
+be either a lead or an opportunity.
+
+Activate the lead stage
+=======================
+
+By default, the lead stage is not activated in Odoo CRM. To activate it,
+go to :menuselection:`Configuration --> Settings`, select the option ""use leads
+if…** as shown below and click on **Apply**.
+
+.. image:: ./media/manual01.jpg

+
+This activation will create a new submenu **Leads** under
+**Sales** that gives you access to a list of all your leads from
+which you will be able to create a new contact.

+
+Create a new lead
+=================
+
+Go to :menuselection:`Sales --> Leads` and click the **Create** button.
+
+.. image:: ./media/manual03.jpg
+	:align: center
+
+From the contact form, provide all the details in your possession
+(contact name, email, phone, address, etc.) as well as some additional
+information in the **Internal notes** field. You can also link the
+lead to an existing company by editing the**Customer** field. Click
+on save and the contact will be visible as a lead in your pipeline .
+
+.. note::
+
+	your lead can be directly handed over to specific sales team and salesperson
+	by clicking on **Convert to Opportunity** on the upper left corner of the screen.
+
+Create a new opportunity
+========================
+
+You can also directly add a contact into a specific sales team without
+having to convert the lead first. On the Sales module, go to your
+dashboard and click on the **Pipeline** button of the desired sales
+team. If you don’t have any sales team yet, :doc:`you need to create one first <../../salesteam/setup/create_team>`.
+Then, click on **Create** and fill in the contact details as shown here
+above. By default, the newly created opportunity will appear on the
+first stage of your sales pipeline.
+
+Another way to create an opportunity is by adding it directly on a
+specific stage. For example, if you have have spoken to Mr. Smith at a
+meeting and you want to send him a quotation right away, you can add his
+contact details on the fly directly into the **Proposition** stage. From
+the Kanban view of your sales team, just click on the **+** icon
+at the right of your stage to create the contact. The new opportunity
+will then pop up into the corresponding stage and you can then fill in
+the contact details by clicking on it.
