# Requirements

Most of the modules used in `time-decode` are readily available in Python 3, however the modules `python-dateutil` and `colorama` are required, and not typically installed by default. When installing `time-decode` using either the [pip (PyPI)](https://digitalsleuth.gitbook.io/time-decode-documentation/installation/using-pip-pypi) method or the [pip (GitHub)](https://digitalsleuth.gitbook.io/time-decode-documentation/installation/using-pip-github) method, these are installed during installation.

When installing via the [Manual Installation](https://digitalsleuth.gitbook.io/time-decode-documentation/installation/manual-installation) method, these will need to be installed before first use.
