# Creating gists for the catalog app
## Introduction
***Note: this article is written for bridge developers only. Creating and using gists for application developers that use the bridge is described here*** \
We recently added the feature to run each example of each Aurelia component in the [**Aurelia KendoUI bridge catalog**](http://aurelia-ui-toolkits.github.io/demo-kendo/#/about/about) app, using the Aurelia [**GistRun**](/kendoui-bridge-developers-notes/creating-gists-for-the-catalog-app.md) tool: \
\
\

\
This GistRun is invoked by a click on the \*\*RUN\*\* button on the \`Autocomplete\` page of the catalog app:\
\
\
\
\
The rest of this article demonstrates the process of adding the \`\*\*RUN\*\*\` button to the \*\*\[combobox basic use]\(\* page.\
\
\*\*\* ### Step 1 Prepare the file \*\*\[registry.json]\(\* by adding the basic definition of the \`gist\` to be used.\
\
\`\`\`javascript { "title": "ComboBox", "documentation": "", "samples": { "basic-use": { "route": \["", "basic-use"], "gist": "" }, "api": { "title": "API", "gist": "" }, "cascading-combobox": { "gist": "" }, "customizing-templates": { "gist": "" }, "grouping": { "gist": "" }, "server-filtering": { "gist": "" }, "virtualization": { "gist": "" }, "events": { "gist": "" } } } \`\`\` \*\*\*\
\
\*\*\* ### Step 2 Create the gists for each of the sample used on this page of the catalog app To avoid the repetition, we will show the creation of just the \*\*ComboBox basic use\*\* gist.\
\
\##### Step 2.1 - create a new Gist Go to to create a new, empty \*\*Gist\*\*\

### Step 2.2 - populate the **Gist**
Drag the four prepared files shown below \
\
\

and drop them on top of the GitHub Gist page which was empty so far, shown on Image 2. Note that this "drag and drop" use is the best workaround for the current lack of GistRun tool's to support the import of the whole project for the gist. \
Now, we have these files added to the the gist: \
\

Note that we also added the Gist title (top of the gist window) "ComoboBox: basic use".
At this point we need to explain what are these four "prebuilt" files we just added to the gist: \
`index.html`
```markup

```
This is the standard "beginning" of any Aurelia application - with a **very big** difference, caused by the line:
