 ### Anaconda
-(coming soon)
+
+**Setup** 
+
+Add channels with dependencies, create a conda environment with `python_version` set to either `2.7.14` or `3.6`, and activate the environment
+
+```
+conda config --add channels conda-forge --add channels marshallmcdonnell --add channels mantid --add channels mantid/label/nightly
+conda create -n addie_env python=${python_version}
+source activate addie_env
+```
+
+**Install**
+
+```
+conda install -c addie-diffraction addie 
+```
+
+**Notes**
+
+If you have an error (see below for example) related to the `libGL` library, you may not have it installed for the Mantid Framework to work. See instructions [here](https://github.com/mantidproject/conda-recipes/#gl-and-glu-libs) for installing the necessary libraries for different OS
+
+Example error:
+`ImportError: First import of "._api" failed with "libGL.so.1: cannot open shared object file...`
+
+If you have an error that another version of Mantid is installed on the machine and being imported via `PYTHONPATH`, you can use the following as a workaround for CLI tool:
+
+```
+PYTHONPATH="" addie
+```
+
+# Usage (CLI reduction tool)
+
+To launch ADDIE, run the following from the command line:
+
+```bash
+addie
+```
+
+If you need to specify the path to Mantid build, use:
+```
+MANTIDPATH=/path/to/mantid/build/bin PATH=$MANTIDPATH:$PATH PYTHONPATH=$MANTIDPATH:$PATH addie
+```
