Dataset name Brief description DOI or URL Terms of use List of traits* (for searching, and also for broader controlled vocabulary/ontology) Geographic extent (for searching) Taxonomic group* (for searching) Temporal extent (for searching)
Recommended or if applicable DOI for paper to cite (or actual citation if no DOI) Description List of taxa (for improved searching) Other useful classes (e.g., life stage, body part, etc.) if the dataset more focused Data standard used? – if not the OT standard Caterina is working on.

$ cd /path/to/repos
$ git clone https://bitbucket.org/railstutorial/sample_app_4th_ed.git sample_app_reference
$ cd sample_app_reference
$ bundle install --without production
Next, migrate the database:
$ rails db:migrate
Finally, run the test suite to verify that everything is working correctly:
$ rails test
If the test suite passes, you'll be ready to run the app in a local server:
$ rails server
To check out the code for a particular chapter, first find the branch name using
$ git branch -a
A branch called remotes/orgin/foo-bar can be checked out using git checkout foo-bar.
Next, copy the contents of the Gemfile using a text editor and then use
$ git checkout chapter-branch-name
to check out the chapter branch. Finally, copy the contents into the Gemfile and run
$ bundle update
At this point, the branch should be working. (You have to copy the Gemfile contents because it's incredibly hard to keep all branches up-to-date, so only the main one is guaranteed to be current.)
