+# Developer Guide
+
+SCDV is developed in Python using [Qt for Python](https://wiki.qt.io/Qt_for_Python). The Python version must be the same as the currently supported version of Blender so that the SCDV [Blender add-on](/blender) will function smoothly.
+
+[[_TOC_]]
+
+## Core Guidelines
+
+- Python [3.9.2](https://www.python.org/downloads/release/python-392/)
+- [Black](https://black.readthedocs.io/en/stable/) for code style/formatting
+- Dependencies managed by [Poetry][]
+- Release packages built with [briefcase](https://beeware.org/project/projects/tools/briefcase/)
+- Supporting Windows, Linux, OSX
+
+> In this early phase of development, Linux and OSX support is not being kept up to date. Even so, always take multi-platform support into account when working on SCDV
+
+## Dependencies
+
+As stated above, SCDV uses [Poetry][] to manage dependencies and requirements. See the `pyproject.toml` file in the repo for what python dependencies are being used in SCDV. During development, however, many changes may actually be done in [scdatatools][]. It's recommended to clone both projects, then use `pip install -e` the local version of scdatatools.

+#### Initial Setup
+Recommended setup:
+
+```bash
+mkdir -p scmodding/{tools,frameworks}/
+
+cd scmodding
+git clone git@gitlab.com:scmodding/tools/scdv.git tools/scdv
+git clone git@gitlab.com:scmodding/frameworks/scdatatools.git frameworks/scdatatools
+
+cd tools/scdv
+poetry install
+poetry run python -m pip install -e ../../frameworks/scdatatools
+```
+
+#### Running
+
+```bash
+poetry run python -m scdv
+```
