🚀 Feature Request

Is your feature request related to a problem? Please describe.

• We want to make the documentation for blast super easy to find.

---

Describe the solution you'd like

• On the home page next to the search the blast database button, we should have a read the docs button that links to the documentation. This would involve editing the https://github.com/astrophpeter/blast/blob/main/app/host/templates/host/index.html file

Additional context

Start reading here: https://blast.readthedocs.io/en/latest/dev_running_blast.html

You should only need to run the slim stack for this change to see if your button works. :-)

To complete this task: Specifically, add something like this after this line: https://github.com/astrophpeter/blast/blob/6effacfdf2979f38ba2de775817bd1224392abab/app/host/templates/host/index.html#L12

to the code:

<a href="https://blast.readthedocs.io/en/latest/index.html" role="button" class="btn btn-primary">Read the docs <i class=""bi bi-book-half""></i></a>

Feel free to customize color etc make sure it is on the same line as the search the blast database button, and make sure it links to the docs.

To add the code, follow the developer workflow here: https://blast.readthedocs.io/en/latest/dev_workflow.html

Feel free to ask any questions you have on this thread :)?
