+### 1. General idea
+
+`oepyhs2nix` is a little comand line interface (CLI) for helping converting
+open-ephys recordings and relacs to one nix file. The task is simple at first
+glance, but what isn't. We have two files and one open-ephys recording file and
+a relacs recording and I want to combine them, so I have both neuronal
+recordings and stimuli in one file.
+
+### 2. Installation
+Here my general workflow for installing the package.
+
+```bash
+git clone https://whale.am28.uni-tuebingen.de/git/awendt/oephys2nix
+cd oephys2nix
+python -m venv .venv
+source .venv/bin/activate
+pip install -e .
+```
+
+To see the documentation you need to install [quarto](https://quarto.org).
+Please follow the installation instructions for quarto, and install the extra
+dependencies.
+
+```bash
+pip install "[.doc]"
+cd doc
+quartodoc build
+quarto preview
+```
+which should open the documentation at localhost:7000.
+
+### 3. Setup
+![setup](assets/setup.png)
+The recorded data gets transfered to relacs and open-ephys were we have
+different sampling rates. If you start a stimulus a TTL pulse is send from
+relacs to the open-ephys recording controler.
+
+:::{.callout-caution}
+The Folder strucutre should be like two folders with one from relacs and one from open-ephys.
+```bash
+relax_folder/
+open-ephys_folder/
+```
