+
+## Summary
+
+<!-- Give a short summary of what the problem is. Note: If you are not sure if BoneReconstructionPlanner works incorrectly or you are not using it as intended then clarify it by asking on the Slicer Forum - https://discourse.slicer.org -->
+
+## Steps to reproduce
+
+<!--
+    Generally, BoneReconstructionPlanner developers can only fix those issues that they can reproduce on their computers.
+
+    To achieve this, please:
+    * Describe in this section what you did, what you expected to happen, and what happened instead.
+    * Attach a few screenshots if possible.
+    * Use one of the BoneReconstructionPlanner sample data sets (in Sample Data module) as inputs. If you cannot reproduce the problem with sample data sets then you can upload your data somewhere and provide a download link here (make sure to remove all patient information from the data before sharing).
+
+    If the problem cannot be reproduced by using the graphical user interface but only by running custom Python or C++ code then please create a short self-contained example as described at http://sscce.org
+
+    To describe "Actual behavior" and "Expected behavior" you may use the following format:
+    1. Do A
+    2. Do B => BoneReconstructionPlanner does Y - OK
+    3. Do C => BoneReconstructionPlanner does Z => ERROR: BoneReconstructionPlanner should do W instead
+    4. Do D => BoneReconstructionPlanner does Z - OK
+    5. Do B => BoneReconstructionPlanner does Y => ERROR: BoneReconstructionPlanner should do X instead
+-->
+
+## Environment
+- BoneReconstructionPlanner version: Slicer-5.??.?-YYYY-MM-DD
+- Operating system: Windows / Linux / Mac + which version

 1. Click the search icon on the left of the module selector and write 'BoneReconstructionPlanner'. Click "Switch to module".
 2. If fibula is the one from the right leg tick "Right side leg" checkbox. This makes fibula coordinate system X axis be always medial independently of the which leg is used to harvest the fibula.
 3. Select the mandibular segmentation and the fibula segmentation.

+2. Optionally, you can add an inter-condylar beam (i.e. a tube model) to the reconstruction. You can create the tube easily from a markups line with points on the condyles using the "Markups To Model" module.

+## Export the planning outputs
+- You may want to [export](https://slicer.readthedocs.io/en/latest/user_guide/data_loading_and_saving.html#export-data) the 3D models you created of mandible and fibula custom surgical guides, and the neomandible. Remember to select the ".stl" export format (which is the format used for 3D printers).
 
 ## Settings
 
 You can use the "Lights rendering" setting to make the 3D visualizations nicer. Try "MultiLamp and Shadows", if you don't like it, you can always go back to "Lamp" default setting.
