+# Build Environment
+
+Building components written in Python has different requirements than the ones written in Java. They are so to speak not really compiled, however they are still packaged in a Python wheel or a tar.gz file.
+
+The image being used is a manylinux2014 image originally based on CentOS 7 and compatible with many Linux OSs. It moreover has several different Python versions pre-installed on it.
+
+## Build the image
+
+The image can be built and tagged with:
+
+```bash
+docker build . -t tdp_builder_python
+```
+
+## Start the container
+
+Contrary to the `tdp-builder` container where components are compiled with maven putting the jar files in the `.m2` cache it is not the case here and therefore volumes, working directories and even users are different for each component.
+
+Check the documentation of the concerned component for the command to start the container.
