### Overview
We need to update the `Languages/Technologies/Tools` information so that visitors to the website can find projects that use specific languages, technologies, or tools.

### Action Items
- [ ] In your IDE, open the `_projects/food-oasis.md` file.
- [ ] Observe the existing syntax of the front matter block [^1] in the file.
- [ ] Find the `tools` variable and remove the following text:
```
- AtlasTI
```
- [ ] Find the `technologies` variable. Add the following text at the bottom of the current list, after 'Material-UI':
```
- ATLAS.ti
```
- Verify the changes by viewing the following in your local environment with Docker, and include 'after' screenshots with your pull request (see the before images below to understand what we are looking for in the after images):
- [ ] Projects page with filter [^2]
- [ ] Food Oasis page [^3]
