 A basic cookiecutter template for most Androiddrew style repos.
 
+## Usage
+
+With [Cookiecutter installed](https://cookiecutter.readthedocs.io/en/stable/), execute the following command and provide your template parameters. 
+
+```
+cookiecutter https://git.runcible.io/androiddrew/cookiecutter-basic
+```
+
+Once templated, you can change into the new project directory and execute the `scripts/bootstrap.sh` script. 
+
+```
+cd <cookiecutter.project_slug>
+./scripts/bootstrap.sh
+```
+
+This will create a Python virtual environment if one is not already enabled, install [pip-tools](https://github.com/jazzband/pip-tools/), compile the requirements.in and dev-requirements.in files, install the initial dependencies, initialize the project as a git repository, and install the [pre-commit hooks](https://pre-commit.com/).
