+====================
+Base report fill PDF
+====================
+
+This module provides a basic report class that fills pdfs.
+
+Installation
+============
+
+Make sure you have ``fdfgen`` Python module installed::
+
+$ pip install fdfgen
+
+For testing it is also necessary ``pdftk`` app installed:
+
+Ubuntu ::
+
+    apt-get install pdftk
+
+OSX ::
+
+  * Install pdftk (https://www.pdflabs.com/tools/pdftk-server/).
+
+Windows ::
+
+  * Install pdftk (https://www.pdflabs.com/tools/pdftk-server/).
+
+Usage
+=====
+
+An example of Fill PDF report for partners on a module called `module_name`:
+
+A python class ::
+
+    from odoo import models
+
+    class PartnerFillPDF(models.AbstractModel):
+        _name = 'report.module_name.report_name'
+        _inherit = 'report.report_fillpdf.abstract'
+    
+        @api.model
+        def get_original_document_path(self, data, objs):
+            return get_resource_path(
+                'report_fillpdf', 'static/src/pdf', 'partner_pdf.pdf')
+
+        @api.model
+        def get_document_values(self, data, objs):
+            objs.ensure_one()
+            return {'name': objs.name}
+
+A computed form can be executed modifying the computing function ::
+
+    from odoo import models
+
+    class PartnerFillPDF(models.AbstractModel):
+        _name = 'report.module_name.report_name'
+        _inherit = 'report.report_fillpdf.abstract'
+
+        @api.model
+        def get_form(self, data, objs):
+            return self.env['ir.attachment'].search([], limit=1)
+
+        @api.model
+        def get_document_values(self, data, objs):
+            objs.ensure_one()
+            return {'name': objs.name}
+
+
+A report XML record ::
+
+     <report
+        id="partner_fillpdf"
+        model="res.partner"
+        string="Fill PDF"
+        report_type="fillpdf"
+        name="report_fillpdf.partner_fillpdf"
+        file="res_partner"
+        attachment_use="False"
+     />
