+### GDAL bindings
+
+To create gdal bindings for given version of python, you need to compile gdal with correct version of python. You can do it by compiling only xdk or from gdal sources from a docker with the python version required. Then you need to create an archive that will be exported later:
+
+```shell
+OTB_VERSION=<MAJOR>.<MINOR>
+PYTHON_VERSION=310 # 3.10 check with python --version
+find xdk/lib/python3/dist-packages/osgeo/ -type f -name "*.so" -printf "%P\n" | tar -czf OTB-${OTB_VERSION}-GDAL-bindings-py${PYTHON_VERSION}.tar.gz --no-recursion -C xdk/lib/python3/dist-packages/osgeo -T -
+```
+
+### Update docker
+
+Since OTB 9.0 we are providing three dockers per version:
+
+* otb on ubuntu 20 with python 3.8
+* otb on ubuntu 22 with python 3.10
+* otb on ubuntu 24 with python 3.12
+
+Before building these dockers, as docker download gdal bindings, you must ensure that gdal bindings for correct python version are available at https://www.orfeo-toolbox.org/packages/archives/OTB/ .
