+## Pip installation
 
 To install aidge_core using pip, run the following command in your python environnement :
 ``` bash
 pip install . -v
 ```
+> **TIPS :** Use environment variables to change compilation options:
+> - `AIDGE_INSTALL` : to set the installation folder. Defaults to `<python_prefix>/lib/libAidge`
+> - `AIDGE_PYTHON_BUILD_TYPE` : to set the compilation mode to **Debug** or **Release** or "" (for default flags). Defaults to **Release**.
+> - `AIDGE_BUILD_GEN` : to set the build backend (for development mode) or "" for the cmake default. Default to "".
+
+
+## Pip installation for development
+
+To setup aidge_core using pip in development (or editable mode), use the `--no-build-isolation -e` options to pip.
 
-**Note:** you can specify a custom install folder by setting an environment variable:
+For instance run the following command in your python environnement for a typical setup :
+``` bash
+export AIDGE_PYTHON_BUILD_TYPE=         # default flags (no debug info but fastest build time)
+export AIDGE_PYTHON_BUILD_TYPE=Debug    # or if one really need to debug the C++ code
+pip install setuptools setuptools_scm[toml] cmake   # Pre-install build requirements (refer to the pyproject.toml [build-system] section)
+pip install -v --no-build-isolation -e .
+```
+
+In this configuration python files can be modified directly without re-installation.
+
+The C++ build dir will be created in `build/` and recompilation and install of python bindings can be done directly with:
+```bash
+make -C build install -j $(nproc)
+# or with cmake
+cmake --build build -j $(nproc) && cmake --install build
+```
 
+One can also use an alternate cmake build backend such as ninja which can be installed easily though pip, for instance :
 ``` bash
-export AIDGE_INSTALL='<path_to_aidge>/install'
+pip install ninja
+export AIDGE_BUILD_GEN=Ninja
+pip install -v --no-build-isolation -e .
+```
+
+In this case ninja is used instead of make as build backend, and recompilation when needed is done with:
+```bash
+ninja -C build install  # note that by default ninja use available parallelism, no need for -j option
+# or with cmake
+cmake --build build && cmake --install build
 ```
 
+Note that python development (or editable mode) is not always robust to changes in the python package setup,
+or when changing the build backend with `AIDGE_BUILD_GEN`.
+In order to re-install when the build breaks, re-execute the commands:
+```bash
+rm -rf *-egg-info build/
+pip install -v --no-build-isolation -e .
+```
+
+
 ## Standard C++ Compilation
 
 Create two directories ``build`` and ``ìnstall``.
