 # PYBAG
 
-Python wrapper for [CBAG](https://github.com/bluecheetah/cbag) library.
+Python wrapper for [CBAG](https://github.com/ucb-art/cbag) library for BAG3++.
 
-This is a fork of [PYBAG] (https://github.com/ucb-art/pybag), which as of May 13th, 2019,
-has been taken offline temporarily.
+## Setup
+
+This library should be used with [BAG3++](https://github.com/ucb-art/bag). To setup BAG, follow the instructions outlined on the [RTD page](https://bag3-readthedocs.readthedocs.io/en/latest/dependencies/).
+
+Alternative, if you are using Ubuntu, you can use the `setup_script.sh` under the `setup` directory. This runs the steps described in the RTD page above. See the `setup/README.md` for discussion.
+
+To build the `pybag` library, run `./run_test.sh`. This will compile `cbag` as well as create the `pybag` Python wrappers for `BAG`.
+
+Running `./run_test.sh`requires the `PYBAG_PYTHON` environment variable be set to the Python from your Miniconda install from the setup process.

+## Files
+- `README.md`: this file
+- `setup_script.sh`: run script. Installs the dependencies as decribed in the RTD.
+- `project-config.template`: a Jinja render template for creating the `project-config.jam` file for the Boost library.
+- `render_template.py`: script to render `project-config.template`
+
+## Usage
+1) Install the following dependencies using `apt`: 
+`autoconf curl gcc-8 g++-8 git libtool libltdl-dev pkg-config make`
+2) Install [Miniconda](https://docs.anaconda.com/miniconda/miniconda-install/) and create the environment using the [environment.yml](https://github.com/ucb-art/pybag/environment.yml) file.
+3) Make an `install` directory to install the dependencies and copy all the files from here to `install`.
+4) Run `./setup_script.sh`
+
+Now you are ready to build `pybag`.
