<p>The code of Synapse is written in Python 3. To do pretty much anything, you'll need <a href="https://www.python.org/downloads/">a recent version of Python 3</a>. Your Python also needs support for <a href="https://docs.python.org/3/library/venv.html">virtual environments</a>.

<p>Synapse can connect to PostgreSQL via the <a href="https://pypi.org/project/psycopg2/">psycopg2</a> Python library. Building this library from source requires access to PostgreSQL's C header files. On Debian or Ubuntu Linux, these can be installed with <code>sudo apt install libpq-dev</code>.</p>
<p>Synapse has an optional, improved user search with better Unicode support. For that you need the development package of <code>libicu</code>. On Debian or Ubuntu Linux, this can be installed with <code>sudo apt install libicu-dev</code>.</p>
<p>The source code of Synapse is hosted on GitHub. You will also need <a href="https://github.com/git-guides/install-git">a recent version of git</a>.</p>
