 # Maybe
+
 We're in the earliest stages (exploratory, really) of building an open source investment tracking + optimization platform.
 
 In its previous life, Maybe was a personal finance and wealth management platform that unfortunately wasn't economically viable. We're now taking another pass in the finance space to see how we can help people grow their wealth in meaningful ways.

-## Stack
+## Code
 
-The tech stack will likely involve some combination of...
+The codebase is vanilla [Rails](https://rubyonrails.org/) w/ [Redis](https://redis.io/), [Puma](http://puma.io/), and [Postgres](https://www.postgresql.org/). Quite a simple setup.
 
-* Ruby
-* Rails
-* Postgres
-* Hotwire (Turbo/Stimulus)
-* Tailwind
+### Setup
 
-May need to look in to something like Timescale, but want to avoid overcomplicating from the start if we can.
+You'll need:
+
+- ruby >3 (specific version is in `Gemfile`)
+- postgresql (if using stock `config/database.yml`)
+
+```shell
+cd maybe
+bundle install
+rails db:setup
+```
+
+You can then run the rails web server:
+
+```shell
+bin/dev
+```
+
+And visit [http://localhost:3000](http://localhost:3000)
