Here's a quick rundown of how to build from source:
1) download or clone the repository ```git clone https://git.sasserisop.com/Sasserisop/MATH201```
2) make sure you have hugo installed
3) if you are using localhost, inside of themes/zettels/assets/js/search.js set 'const localhost' to true.
4) open a command prompt in the MATH201/ directory and run the command ```hugo server --disableFastRender```
5) visit your site by opening http://localhost:1313 on your browser.
3) open a command prompt in the MATH201/ directory and run the command ```hugo server --disableFastRender```
4) visit your site by opening http://localhost:1313 on your browser.
Now if you want to host it on a live website, you can run:
```hugo```
