+# Ribica front office API
+
+## Getting started:
+
+1. install postgresql and libraries (for native 'pg' gem to be able to compile)
+2. run `bundle install`
+3. create postgresql user protected with password 
+4. create postgresql database 
+5. copy config.rb.example to config.rb and change the information inside of it
+6. run `rake db:schema:load`
+7. run `gem install rerun`
+
+## Running dev server (with autoreloading)
+
+1. run `rerun ruby app.rb`
+
+##  Generating migrations 
+
+Sinatra has a different syntax than rails to generate migration: 
+
+`rake db:create_migration NAME=create_categories`
+
+## Handling shared models
+
+Some of models will necesarrily be shared between front and back office. 
+Migrations for those models *must be in front office* and 
+back office will just have a model file with custom code if needed.
+
+When generating active scaffold - migration is generated by default so it 
+needs to be removed before using it.
