 ### Basic benchmark
 
-To run a benchmark, you can simply call `hyperfine <command>...` where the argument(s) can be any shell command. For example:

 ``` bash

 ```
 
-Hyperfine will automatically determine the number of runs to perform for each command. By default, it will perform *at least* 10 benchmarking runs. To change this, you can use the `-m`/`--min-runs` option:

 ### I/O-heavy programs
 
-If the program execution time is limited by disk I/O, the benchmarking results can be heavily influence by disk caches and whether they are cold or warm.
