+# Summary
+
+
+Overlapping event responses, (non-)linear effects and confounds, outliers, item effects - all pretty common features limiting the application of neuroimaging methods. Here, we focus on EEG without loss of generality. Especially event-related potentials in naturalistic paradigms (e.g. ET+EEG, VR+EEG, MoBi) but also classical paradigms (evidence Integration, language, even oddball tasks) require such techniques. 
+
+Unfold.jl implements the model fitting based on the popular wilkinson~formula+syntax. It is feature-par with matlab-unfold. In addition it offers speed-improvements (up to 100x on GPUs) and extensions for outlier-robust fits, back2back regression, and mixed models.
+
+While implemented in Julia, it is straight forward to also call from Python and tutorials are available.

+# Statement of need
+
+
+
+# Mathematics
+
+Single dollars ($) are required for inline mathematics e.g. $f(x) = e^{\pi/x}$
+
+Double dollars make self-standing equations:
+
+$$\Theta(x) = \left\{\begin{array}{l}
+0\textrm{ if } x < 0\cr
+1\textrm{ else}
+\end{array}\right.$$
+
+You can also use plain \LaTeX for equations
+\begin{equation}\label{eq:fourier}
+\hat f(\omega) = \int_{-\infty}^{\infty} f(x) e^{i\omega x} dx
+\end{equation}
+and refer to \autoref{eq:fourier} from text.

+# Citations
+
+Citations to entries in paper.bib should be in
+[rMarkdown](http://rmarkdown.rstudio.com/authoring_bibliographies_and_citations.html)
+format.
+
+If you want to cite a software repository URL (e.g. something on GitHub without a preferred
+citation) then you can do it with the example BibTeX entry below for @fidgit.
+
+For a quick reference, the following citation commands can be used:
+- `@author:2001`  ->  "Author et al. (2001)"
+- `[@author:2001]` -> "(Author et al., 2001)"
+- `[@author1:2001; @author2:2001]` -> "(Author1 et al., 2001; Author2 et al., 2002)"
+
+# Figures
+
+Figures can be included like this:
+![Caption for example figure.\label{fig:example}](figure.png)
+and referenced from text using \autoref{fig:example}.
+
+Figure sizes can be customized by adding an optional second parameter:
+![Caption for example figure.](figure.png){ width=20% }
