 ## Installation
 
-Recommended install in a virtual environment.
+It is recommended that tm2install in a virtual environment.
 
 Stable (to come - use bleeding edge for now):
-
 ```bash
 pip install tm2py
 ```
 
-Bleeding edge:
-TODO: Which environment is this?  Does it still work for anyone?
+For Developers, it is recomended that the following instructions are used to install  
+*Note: The Python Environment has recently been updated to python 3.11, there may be some instabilites with current build*
+```bat
+git clone --branch develop https://github.com/BayAreaMetro/tm2py.git
 
-```bash
-conda env create -f environment.yml
+conda create -n tm2py python=3.11.9
 conda activate tm2py
-pip install git+https://github.com/bayareametro/tm2py@develop
-```

-The above directions didn't work for the MTC Windows environment.  The following method did work, on a machine with Emme-4.6.0 installed.  This required a compiled GDAL/Fiona package set for python 3.7, this can be found in the [lib directory](/lib/) , consisting of the following:
-
-1. GDAL-3.3.2-cp37-cp37m-win_amd64.whl
-2. pyproj-3.2.1-cp37-cp37m-win_amd64.whl
-3. Fiona-1.8.20-cp37-cp37m-win_amd64.whl
-4. Shapely-1.8.1-cp37-cp37m-win_amd64.whl
-5. geopandas-0.10.2-py2.py3-none-any.whl
-
-With these files in hand, the following installation instructions work:
+conda install gdal
+conda install pyproj
+conda install fiona
+conda install shapely
+conda install geopandas
 
-```bat
-conda create -n tm2py python=3.7.6
-conda activate tm2py
-pip install [the packages listed above, in that order]
 cd <path to tm2py git directory>
+git 
 pip install -e .
 conda env config vars set GDAL_VERSION=3.3.2
 ```
 Finally, install the Emme python packages using the Emme GUI. This effectively creates a file,
 `C:\Users\%USERNAME%\.conda\envs\tm2py\Lib\site-packages\emme.pth` with the following contents, so you could create the file yourself.
 
 ```python
-import os, site; site.addsitedir("C:/Program Files/INRO/Emme/Emme 4/Emme-4.6.0/Python37/Lib/site-packages")
+import os, site; site.addsitedir(os.path.join(os.environ["EMMEPATH"], "Python311/Lib/site-packages"))
+```
+
+*This should start Emme OpenPath, if it does not you should be able to manually set the correct version of emme such as below*
+```python
+import os, site
+os.environ["EMMEPATH"] = r"C:\Program Files\Bentley\OpenPaths\EMME 24.00.00"
+site.addsitedir(os.path.join(os.environ["EMMEPATH"], "Python311/Lib/site-packages"))
 ```

 In troubleshooting, sometimes DLL load failure errors would occur which may be resolved by importing gdal before importing emme packages. Emme support explained this thusly:
 
 At load time, the EMME API will always load the geos_c co-located with the EMME API, unless it was already loaded from some other location, which is the case when you import GDAL first. EMME API seems to be compatible with the newer GDAL/geos_c (reminder: not tested!). But this does not appear to be the case the other way around (newer GDAL is not compatible with older geos_c).
