+# Generation Sphinx Documentation
+
+Before being able to generate the Docs, make sure to install all the python dependencies: `pip install -r requirements.txt` and pandoc. However, they can be ignored since they don't lead to any actual issues. To generate the Sphinx documentation HTML page, run the following commands (Linux):
+
+```bash
+cd /path/to/topotoolbox/docs/
+make clean
+make html
+```
+
+then open the `pytopotoolbox/docs/_build/html/index.html` file in your browser.

+How to install
+==============
+
+Generating/Installing distribution archives
+-------------------------------------------
+
+For any operating system, install the following:
+
+- **Python**
+- **pip**
+- **Git** (only when *building* the package yourself)
+
+Linux
+~~~~~
+
+**Installing from .whl file**
+
+Make sure to choose the appropriate file for your OS. For Linux, the file name should contain something like: `linux_x86_64`
+
+.. code-block:: bash
+
+    pip install dist_name.whl
+
+**Installing directly from the repository:**
+
+.. code-block:: bash
+
+    cd path/to/pytopotoolbox
+    pip install .
+
+**Generating distribution archives**
+
+.. code-block:: bash
+
+    cd path/to/pytopotoolbox
+    python3 -m pip install --upgrade build
+    python3 -m build
+
+Windows
+~~~~~~~
+
+**Installing from .whl file**
+
+Make sure to choose the appropriate file for your OS. For Windows, the file name should contain something like: `win_amd64`.
+
+.. code-block:: bash
+
+    pip install dist_name.whl
+
+**Installing directly from the repository:**
+
+Since there are C/C++ files that need to be compiled in order to build the package, there are a few extra steps to take.
+
+1. Install the `Developer Command Prompt for VS 2022 <https://visualstudio.microsoft.com/downloads/>`_.
+    - Scroll down to '*All Downloads*'
+    - Open '*Tools for Visual Studio*'
+    - Download '*Build Tools for Visual Studio 2022*'
+    - Install it while including the '*Desktop development with C++*' workload
+2. To ensure the compiler is working with 64-bit architecture, that is necessary for python, **open 'x64 Native Tools Command Prompt for VS 2022'** instead of the '*Developer Command Prompt*' that defaults to 32-bit architecture.
+3. In the newly opened terminal, run:
+
+    .. code-block:: bash
+
+        cd path\to\pytopotoolbox
+        pip install .
+
+**Generating distribution archives**
+
+Open the 'x64 Native Tools Command Prompt for VS 2022' Terminal and run:
+
+.. code-block:: bash
+
+    cd path\to\pytopotoolbox
+    py -m pip install --upgrade build
+    py -m build
