+## Requirements.
+
+Python 3.4+
+
+Recommended: Python 3.7+
+
+The recommended is Python 3.7+ for compatibility with Python Catbuffer library generated by [catbuffer-generators](https://github.com/nemtech/catbuffer-generators)
+
+## Installation & Usage
+### pip install
+
+If the python package is hosted on a repository, you can install directly using:
+
+```sh
+pip install git+https://{{gitHost}}/{{{gitUserId}}}/{{{gitRepoId}}}.git
+```
+(you may need to run `pip` with root permission: `sudo pip install git+https://{{gitHost}}/{{{gitUserId}}}/{{{gitRepoId}}}.git`)
+
+Then import the package:
+```python
+import {{{packageName}}}
+```
+
+### Setuptools
+
+Install via [Setuptools](http://pypi.python.org/pypi/setuptools).
+
+```sh
+python setup.py install --user
+```
+(or `sudo python setup.py install` to install the package for all users)
+
+Then import the package:
+```python
+import {{{packageName}}}
+```
+
+## Getting Started
