+Welcome to [https://stemformulas.com/](https://stemformulas.com/), the site with the goal of being the best place in the world to look for STEM-related formulas.
+
+## Features:
+- 63 formulas and counting (we gotta pump those numbers up)
+- The search bar is in focus on site load for quick searching
+- The / key can be used to open the search on any page
+- LaTeX can be copied by clicking on it on any formula's page
+- The site has open-graph tags, so a full preview of the formula is shown when its page is shared on social media
+- The site is mobile-friendly

 3. Copy the reply from ChatGPT and paste it into the second tab of the Python GUI, which will fix some of the LaTeX formatting. This can usually now be put into an index.md file, with all of the grunt work done. Make sure to fully proofread what ChatGPT gives you, as it is crucial that formulas put on the site are correct.
 
 ## Possible future work
+- More formulas of course
 - Formula sheet maker
-- Docker build for easier contributions
 - Better SEO
+- Differentiate constants from variables
+- More examples for formula usage
