 # Features
 
-- Always on and ready to receive additional tasks
-- Configurable concurrency limit
-- Configurable queue capacity limit
-- Configurable priority per individual tasks
-- Configurable queue timeout duration per individual tasks
-- Pause/resume queue execution
-- Compatible for browsers as well as Node.js environments
-- Written in TypeScript, full type definitions built-in
-- Provides both CJS and ESM builds

-#### rampUpTime:
+#### `rampUpTime`:
 
 If specified a non-zero number, will delay the concurrency-ramping-up time of additional job executions, one by one, as the instance attempts to reach maximum configured concurrency.
 Represents number of milliseconds.
