 # roda-templates
 
 Install prereq: sudo apt install puma, sudo gem install roda --no-document
+## Setup
+
+### Prereq installs
+
+Will need ruby; install it via package manager or a ruby manager like rbenv/ruby-build.  Will need the roda gem, and then an application server such as puma (recommended), gunicorn, or passenger.  My examples will use system ruby and puma.
+
+#### Option 1: System wide packages
+
+With this example, will basically just ignore the project's Gemfile.  Debian 12 has a pretty current ruby version, just use it.  It will get pulled in as a required package for puma.
+
+```
+sudo apt install puma ruby-rack
+sudo gem install roda
+```
+
+#### Option 2: Bundler
+
+Run the bundle command from the project's root directory
+
+```
+sudo apt install ruby ruby-bundler
+bundle install
+```
+
+## Run it
+
+In the project root directory:
+
+```
+puma
+```
+
+This default to development mode.  Run it in production mode with:
+
+```
+RACK_ENV=production puma
+```
