+# PyGhidra Crusader Toolkit
+
+This toolkit drives the local PyGhidra fallback workflow for the Crusader Ghidra project.
+
+## Defaults
+
+- Ghidra install dir: `I:\Apps\ghidra_12.0.4_PUBLIC`
+- Python env: `.venv-pyghidra311`
+- Python base interpreter: `C:\Users\Maddo\.pyenv\pyenv-win\versions\3.11.6\python.exe`
+- CLI entrypoint: `.\.venv-pyghidra311\Scripts\python.exe -m tools.pyghidra_crusader`
+
+## Bootstrap Or Refresh
+
+Run this from the repo root to create or refresh the local environment against the bundled Ghidra 12.0.4 offline packages:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\tools\pyghidra_crusader\bootstrap_env.ps1
+```
+
+The script recreates or refreshes `.venv-pyghidra311`, then installs these pinned packages from the local Ghidra tree:
+
+- `pyghidra==3.0.2` from `Ghidra\Features\PyGhidra\pypkg\dist`
+- `ghidra-stubs==12.0.4` from `docs\ghidra_stubs`
+
+Override the defaults when needed:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\tools\pyghidra_crusader\bootstrap_env.ps1 `
+  -PythonExe C:\Path\To\python.exe `
+  -GhidraInstallDir I:\Apps\ghidra_12.0.4_PUBLIC `
+  -VenvPath .\.venv-pyghidra311
+```
+
+## Validation
+
+After bootstrap, validate package versions and the project-open path:
+
+```powershell
+.\.venv-pyghidra311\Scripts\python.exe -m tools.pyghidra_crusader project-files
+```
+
+If you need to target a different installed Ghidra tree temporarily, set `GHIDRA_INSTALL_DIR` or pass `--install-dir` to the CLI.
