 :fas:`screwdriver-wrench;fa-fw` Installation
 ============================================
 
+**pyecsca** consists of three repositories:
+
+.. grid:: 1 1 3 3
+
+    .. grid-item-card::  Core
+
+        The `core <https://github.com/J08nY/pyecsca>`_ repository contains the core of the
+        functionality, except the code generation and notebooks.
+
+    .. grid-item-card::  Codegen
+
+        The `codegen <https://github.com/J08nY/pyecsca-codegen>`_ repository contains
+        the code generation functionality.
+
+    .. grid-item-card::  Notebook
+
+        The `notebook <https://github.com/J08nY/pyecsca-notebook>`_ repository contains
+        example notebooks that showcase functionality of the toolkit.
+
+
+Core
+====
+
+The core package can be installed either from `pypi <https://pypi.org/project/pyecsca/>`__ or from the
+`source repository <https://github.com/J08nY/pyecsca>`__. There are several extras that can be installed:
+
+- `picoscope_sdk` to enable support for PicoScope oscilloscopes using the picosdk_ package.
+- `picoscope_alt` to enable support for PicoScope oscilloscopes using the picoscope_ package.
+- `chipwhisperer` to enable support for ChipWhisperer_ targets and oscilloscopes.
+- `smartcard` to enable support for smartcard targets using the pyscard_ package.
+- `leia` to enable support for smartcard targets using the leia_ (smartleia) package.
+- `gmp` to enable arithmetic via gmpy2_ (which may or may not be faster).
+- `flint` to enable arithmetic via python-flint_ (which may or may not be faster).
+- `pari` to enable faster division polynomial computation using cypari2_.
+- `dev` to install several packages used in development.
+- `test` to install several packages used for testing.
+- `doc` to install several packages used for building documentation.
+
+You can install these extras like this:
+
+.. code-block:: shell
+
+    pip install pyecsca[smartcard,gmp]
+
+.. note::
+
+    The core repository uses git submodules, make sure to check them out after cloning with: ``git submodule update --init``.
+
+
+The core package contains data from the `Explicit-Formulas Database`_ by Daniel J. Bernstein and Tanja Lange.
+The data was partially changed, to make working with it easier. It is available on Github at `crocs-muni/efd`_.
+
+It uses `ChipWhisperer`_ as one of its targets. It also supports working with Riscure_ Inspector trace sets, which are of a proprietary format.
+
+Optionally, you can Cythonize the ``pyecsca/ec/mod`` subpackage and sometimes gain a performance benefit, YMMV.

+Codegen
+=======
+
+The codegen package requires (and bundles in ``ext/libtommath`` as a git submodule) a version
+of the libtommath library. The package can be either installed from `pypi <https://pypi.org/project/pyecsca-codegen/>`__ or from the
+`source repository <https://github.com/J08nY/pyecsca-codegen>`__. Note that currently, the pypi project
+contains the built package for x86_64 Linux only. Thus, installation from source is preferable.
+
+Assuming you have ``make``, a C compiler and a C cross-compiler for ```arm-none-eabi`` you can just run:
+
+.. code-block:: shell
+
+    pip install .
+
+inside the codegen repository and it should be built and installed automatically.
+
+.. note::
+
+    The codegen repository uses git submodules, make sure to check them out after cloning with: ``git submodule update --init``.
+
+Notebooks
+=========
+
+The notebook repository is included as a submodule in the core repository.
+However, this version can get outdated during active development.
