 # What Is It?
 - A REST testing and API microbenchmarking tool
 - Tests are defined in basic YAML or JSON config files, no code needed
-- Minimal dependencies (pycurl, pyyaml, future), making it easy to deploy on-server for smoketests/healthchecks
+- Minimal dependencies (pycurl, pyyaml, optionally future), making it easy to deploy on-server for smoketests/healthchecks
 - Supports [generate/extract/validate](advanced_guide.md) mechanisms to create full test scenarios
 - Returns exit codes on failure, to slot into automated configuration management/orchestration tools (also supplies parseable logs)
 - Logic is written and [extensible](extensions.md) in Python
