 # Distill Templates
 
+This is the repository for the distill web framework. If you're interesting in just using the framework to write an article for the [Distill journal](http://distill.pub), visit http://distill.pub/guide/. 
+
+The general process for using this framework is to hotlink the compiled code in your dev environment. 
+
+```html
+<script src="http://distill.pub/template.v1.js"></script>
+```
+
+You can also install it as a local dependency through npm or with [yarn](https://yarnpkg.com).
+
+```
+npm install --D distill-template
+```
+
+If you're interested in submitting pull requests or developing on the framework itself, read on.
+
 ## Development
 
-Run `yarn start` to start a watching build rollup server.
+Run `yarn start` to start a watching build rollup server. To view the sample pages in the repo, you can run `yarn serve` as a separate process which starts a static server. `yarn build` will run a one-time build.
 
 ## Testing
 
 Run `yarn test`. That's it.

-  <p>We often think of Momentum as a means of dampening oscillations and speeding up the iterations, leading to faster convergence. But it has other interesting behavior. It allows a larger range of step-sizes to be used, and creates its own oscillations. What is going on?</p>

-  <h2>A Brief Survey of Techniques</h2>
-  <p>Before diving in: if you haven’t encountered t-SNE before, here’s what you need to know about the math behind it. The goal is to take a set of points in a high-dimensional space and find a faithful representation of those points in a lower-dimensional space, typically the 2D plane. The algorithm is non-linear and adapts to the underlying data, performing different transformations on different regions. Those differences can be a major source of confusion.</p>

-  <p>Here's a test of an inline equation <d-math>c = a^2 + b^2</d-math>. Also with configurable katex standards just using inline '$' signs: $$x^2$$ And then there's a block equation:</p>

-  <p>Math can also be quite involved:</p>
-  <d-math block>
-    \frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} = 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}} {1+\cdots} } } }

+# Gulp with Mustache Templates
+
+To get started, make sure to run `yarn install` or `npm install` to install dependencies.
+
+Run `gulp` to build the project. Running `gulp serve` will run a watching server.
+
+There is very little processing going on, the only thing we've added is support for mustache partials.
