 ### Easiest way
-  
\ No newline at end of file
+  
+If you are using docker you can follow these steps to migrate your repository:
+
+1. Create a base folder for conversion
+
+        mkdir -p /tmp/convert
+        
+2. Clone your odoo repository into folder called odoo
+
+        git clone https://github.com/jamotion/sale-workflow.git /tmp/convert/odoo
+
+3. Start Conversion with following command:
+
+        docker run --rm -ti -v /tmp/convert:/opt/migrator/data flecom/odoo2flectra --name "Sale Workflow"
+        
+4. When conversion is finished, you will find the converted repository in folder /tmp/convert/flectra
+
+        ls /tmp/convert/flectra
+        
+### Manual way
+
+If you do not use docker (why not!?!), it is possible to run the python script manually.
+For this python > 3.5 and jinja package are required.
+
+1. Clone this repository with:
+
+        git clone https://gitlab.com/flectra-community/devops/odoo-2-flectra-converter.git
+        cd odoo-2-flectra-converter
+        chmod +x migrate_repository.py
+        
+2. Clone your odoo repository into folder called odoo
+
+        git clone https://github.com/jamotion/sale-workflow.git ./odoo
+
+3. Start Conversion with following command:
+
+        ./migrate_repository --name "Sale Workflow"
+        
+4. When conversion is finished, you will find the converted repository in folder ./flectra
+
+        ls ./flectra
+
