+#### Adding parameters to the sofa
+Each part can have multiple parameters like resistance, voltage or capacitance. For the sofa length and weight make sense. Each parameter has a parameter template that combines the parameter name with a unit. So we first have to create the parameter templates and afterwards add the parameter values to the sofa.
+
+```python
+from inventree.base import Parameter
+from inventree.base import ParameterTemplate
 
-## Before we can add parameters to the couch, we neeed to create the parameter templates
-## These parameter templates need to be defined only once and can be used for all other parts. 
 LengthTemplate = ParameterTemplate.create(api, { 'name' : 'Length', 'units' : 'Meters' })
 WeightTemplate = ParameterTemplate.create(api, { 'name' : 'Weight', 'units' : 'kg' })
 
-## Now we create the parameters
 ParameterLength = Parameter.create(api, { 'part': couch.pk, 'template': LengthTemplate.pk, 'data' : 2 })
 ParameterWeight = Parameter.create(api, { 'part': couch.pk, 'template': WeightTemplate.pk, 'data' : 60 })
+```
+These parameter templates need to be defined only once and can be used for all other parts. Lets finally add a picture.

 #### Adding a location to the sofa
 
 If we have several sofas on stock we need to know there we have stored them. So let’s add stock locations to the part. Stock locations can be organized in a hierarchical manner e.g. boxes in shelves in aisles in rooms. So each location can have a parent. Let’s assume we have 10 sofas in box 12 and 3 sofas in box 13 located in shelve 43 aisle 3. First we have to create the locations, afterwards we can put the sofas inside.

 Supplier and manufacturer are added with just one command. The SKU is the code under which the couch is listed in the store.

+#### Add a datasheet or other documents
+We have the possibility to add documents to the part. We can use pdf for documents but also other files like 3D drawings or pictures. To do so we add the following commands:
+
+```python
+from inventree.part import PartAttachment
+
+PartAttachment.upload_attachment(api, pk, **{'comment':'Datasheet', 'attachment':'manual.pdf'} )
+PartAttachment.upload_attachment(api, pk, **{'comment':'Drawing', 'attachment':'sofa.dxf'} )
+```
+Here pk is the primary key of the part where the attachment will be added, comment is a name of the attachment that can be freely chosen and attachment is a file that must exist.
