 ## What is kithe?
 
 Kithe is a toolkit for building digital collections/repository applications in Rails. It comes out of experience in the [samvera](https://samvera.org/) community of open source library-archives-museums digital collections/preservation work (but is not a samvera project).

 So you want to start an app that uses kithe. We should later provide better 'getting started' guide. For now some sketchy notes:
 
 * Again re-iterate that kithe requires your Rails app use postgres, 9.5+.
 
-* kithe requires Rails 5.2 or 6.0.
+* kithe works with Rails 5.2 through 6.1.
 
 * To install migrations from kithe to setup your database for it's models: `rake kithe_engine:install:migrations`
 
 * Kithe view support generally assumes your app uses bootstrap 4, and uses [simple form](https://github.com/plataformatec/simple_form) configured with bootstrap settings. See https://github.com/plataformatec/simple_form#bootstrap . So you should install simple_form and bootstrap 4.

 * Note we are currently using the standard rails-generated dummy app in spec/dummy for testing, rather than [engine_cart](https://github.com/cbeer/engine_cart) or [combustion](https://github.com/pat/combustion).
   * Before you run the tests for the first time, create the database by running: `rails db:setup`. This will create two databases, kithe_development and kithe_test.
-  * We do use [appraisal](https://github.com/thoughtbot/appraisal) to test under multiple rails versions,but still wtih the standard dummy app. It works for both Rails 5.2 and 6.0, because Rails structure changes have settled down.
+  * Some of the rspec tests depend on [FFmpeg](https://ffmpeg.org/) for testing file derivative transformations. Mac users can install [ffmpeg via homebrew](https://formulae.brew.sh/formula/ffmpeg): `brew install ffmpeg`
+  * We do use [appraisal](https://github.com/thoughtbot/appraisal) to test under multiple rails versions, but still with the standard dummy app. It works for both Rails 5.2 and 6.0, because Rails structure changes have settled down.
   * Locally you can run `bundle exec appraisal rspec` to run tests multiple times for each rails we have configured, or eg `bundle exec appraisal rails-60 rspec` for a particular one.
   * If the project `Gemfile` _or_ `Appraisal` file changes, you may need to re-run `bundle exec appraisal install` and commit changes.
 
 You can use all rails generators (eg `rails g model foo`) and it will generate properly for engine,
 including module namespace. You can generally use rake tasks and other rails commands for dummy app, like `rake db:create` etc.
