 Plugin Template
 ===============
 
+This repository is intended to be used as a quickstart for writing a plugin
+library consistent with [PluginPlay](https://github.com/NWChemEx/PluginPlay).
+
+## Generating the New Plugin
+
+This template is generated with the 
+[Cookiecutter](https://github.com/cookiecutter/cookiecutter) package:
+
+```bash
+# Install cookiecutter, if not already
+$ pip install cookiecutter
+# Generate the template
+$ cookiecutter https://github.com/NWChemEx/PluginTemplate.git
+```
+Follow the resulting to prompts to generate your plugin. The resulting directory
+will contain the following:
+- `version.txt` - Holds the version of the plugin. Used by `CMakeLists.txt`.
+- `default_toolchain.cmake` - A simple CMake toolchain. Ignored by Git.
+- `include/{plugin_name}/{plugin_name}.hpp` - An initial courtesy header file.
+- `include/{plugin_name}/{plugin_name}_mm.hpp` - A header file declaring the plugin.
+- `src/{plugin_name}/{plugin_name}_mm.cpp` - A source file defining the the plugin.
+- `tests/unit_tests/test_main.cpp` - A main source file for a Catch2 test.
+- `tests/unit_tests/test_load_modules.cpp` - A source file for a test of the `load_modules` function.
+
+These files constitute a bare plugin library and a simple test for the 
+`load_modules` function. New modules and property types can be added and
+registered following the [PluginPlay tutorials](https://nwchemex.github.io/PluginPlay/tutorials/index.html).
+The resulting library will depend on [SimDE](https://github.com/NWChemEx/SimDE).
+See [here](https://nwchemex.github.io/SimDE/install.html#simde-dependencies) for
+the further info on SimDE's dependencies. You can configure, build, and test the
+new plugin as follows:
+
+```bash
+$ cmake -Bbuild -H. -DCMAKE_TOOLCHAIN_FILE=./default_toolchain.cmake -DCMAKE_INSTALL_PREFIX=./install
+$ cmake --build build --parallel 2
+$ cd build
+$ ctest -VV
+```
+
+At this point, you can initialize git and set up remotes:
+
+```bash
+$ git init
+$ git add .
+$ git commit -m "Initial State"
+$ git remote add origin {Your Remote Repo}
+$ git push -u origin master
+```
