 # Building FreeCAD on Mac OS 10.15.x -- Catalina #
 
-## Obtain Dependencies ##
+General notes on how the tooling works:
 
-The [FreeCAD Wiki](https://wiki.freecadweb.org/Third_Party_Libraries) has
-a list of required deps. They are reproduced here for developers.
+This setup uses [conda](https://docs.conda.io) for dependency management.
+Conda is able to pull the deps from a repository called conda-forge and
+setup an isolated build environment. Not quite as isolated as docker, but
+it is a good option for Mac and its what the FreeCAD CI system uses.

+Once the dependencies are installed into a conda environment, then the
+build uses the standard `cmake` configuration process to configure the build
+and `ninja` to invoke the actual compilation against whatever host compiler
+(gcc, clang, etc.) was installed by conda's `cxx-compiler` package for
+that architecture.
 
-`*`: Deprecated
+All of this, and some sanity checks, are in a unified shell script. See below.
 
-The easiest way on Mac to get the Dependencies is homebrew.
+# Directions #
 
-### Building MED ###
+## Install XCode Command line tools ##
 
-Note that the tests don't compile on GCC 10 or GCC 7. Kind of concerning.
-Also we end up w/ MED using HDF5 @ 1.10 and VTK using 1.12... does this work?
-```
-mkdir build && \
-pushd build && \
-cmake -G Ninja \
-  -DMEDFILE_BUILD_TESTS=OFF \
-  -DHDF5_ROOT_DIR=/usr/local/opt/hdf5@1.10 ../ \
-  && ninja \
-  && ninja install
-```
+Run `xcode-select --install` and click through.
 
-## Run CMake ##
+## Install Conda ##
+
+Refer to [MiniConda Docs](https://docs.conda.io/en/latest/miniconda.html).
+
+## Run the shell script ##
+
+Run the `./build_unix_dev_conda.sh` and go get coffee. Builds take
+an hour+ on a 2012 Retina MacBook.
+
+Output binaries will be in the `./build/bin/FreeCAD` *and*
+`${CONDA_PREFIX}/bin/FreeCAD` directories.
+
+You can code/build/test using the cmake configuration folder `./build` in
+the standard way *from withing the freecad_dev conda enviroment*.
 
-```
-mkdir freecad-build
-cd freecad-build
-cmake ../freecad-source \
-  -DBUILD_QT5=ON \
-  -DPYTHON_EXECUTABLE=/usr/local/bin/python3 \
-  -DHOMEBREW_PREFIX=/usr/local
-make -j$(nproc --ignore=2)
