+## Development setup ##
+
+ANYstructure is currently maintained as a Python package named `anystruct`. The GUI can still be launched through the `ANYstructure` console command after an editable install.
+
+Recommended local setup:
+
+```powershell
+python -m venv .venv
+.\.venv\Scripts\Activate.ps1
+python -m pip install --upgrade pip
+python -m pip install -r requirements-dev.txt
+python -m pip install -e .
+python -m pytest
+```
+
+Launch the desktop app after installation:
+
+```powershell
+ANYstructure
+```
+
+Dependency groups are also available for focused installs:
+
+```powershell
+python -m pip install -r requirements-core.txt
+python -m pip install -r requirements-ml.txt
+python -m pip install -r requirements-excel.txt
+```
+
+Equivalent package extras are exposed as `core`, `ml`, `excel`, `dev`, and `all`. The default package install still includes Excel and ML dependencies for backwards compatibility.
+
+Excel project import requires a local Excel installation and is not expected to run in basic automated tests.
+The external Excel-sheet DNV PULS calculation workflow has been removed from this release; ML-CL remains available.
+
 ## The following is calculated: ##
 * Minimum plate thickness (DNV-OS-C101)
 * Minimum section modulus of stiffener/plate (DNVGL-OS-C101)
 * Minimum shear area (DNVGL-OS-C101)
-* Buckling (DNVGL-RP-C201)or PULS (licenced DNV software)
+* Buckling (DNVGL-RP-C201)
 * Buckling strength of shells DNV-RP-C202
-* PULS buckling (DNV license needed)
 * Machine learning buckling, PULS based
 * Fatigue for plate/stiffener connection (DNVGL-RP-C203)
