+## How to contribute to NES
+
+1. Create an issue and complete the description
+   - Complete the description of the issue as much as you can with (estimation time, milestone, assigned one, ...)
+2. Create a branch (from master) directly in the issue (name should start with `develop-` following the number and title of the issue)
+3. Clone and checkout to the new branch without modifications in Nord3v2.
+   - It is recommended to run some tests to ensure the current behaviour.
+4. Modify the code.
+5. Run the simulation with the new branch:
+   - To achieve it is important to prepend the cloned path in the `PYTHONPATH`
+   - e.g., `export PYTHONPATH=/gpfs/scratch/bsc32/bsc32538/NES:${PYTHONPATH}`
+6. Run tests
+7. Merge `master` into your development branch.
+   - To ensure that if there have been news on the master they are included.
+8. Run all tests.
+9. Create a merge request assigning it to Alba or Carles

 ## Vertical interpolation
 
 - [Numpy linear interpolation](https://numpy.org/doc/stable/reference/generated/numpy.interp.html) is faster than [scipy.interpolate.interp1d](https://docs.scipy.org/doc/scipy/reference/generated/scipy.interpolate.interp1d.html)
