 This is the app running on https://api.travis-ci.org/
 
+## Requirements
+
+1. PostgreSQL 9.3 or higher
+1. Redis
+1. RabbitMQ
+
 ## Installation
 
-Setup:
+### Setup
 
     $ bundle install
 
-Run tests:
+### Database setup
+
+1. `rake db:create db:structure:load`
+1. Clone `travis-logs` and copy the `logs` database (assume the PostgreSQL user is `postgres`):
+```sh-session
+cd ..
+git clone https://github.com/travis-ci/travis-logs.git
+cd travis-logs
+rvm jruby do bundle exec rake db:migrate # `travis-logs` requires JRuby
+psql -c "DROP TABLE IF EXISTS logs CASCADE" -U postgres travis_development
+pg_dump -t logs travis_logs_development | psql -U postgres travis_development
+```
+
+Repeat the database steps for `RAILS_ENV=test`.
+```sh-session
+RAILS_ENV=test rake db:create db:structure:load
+pushd ../travis-logs
+RAILS_ENV=test rvm jruby do bundle exec rake db:migrate
+psql -c "DROP TABLE IF EXISTS logs CASCADE" -U postgres travis_test
+pg_dump -t logs travis_logs_test | psql -U postgres travis_test
+popd
+```
+
+
+### Run tests
 
-    $ RAILS_ENV=test rake db:create db:structure:load
     $ rake spec
