 # HTTPie Benchmarking Infrastructure
 
-This directory includes the benchmarks we
-use for testing HTTPie's speed and the infrastructure
-to automate this testing accross versions.
+This directory includes the benchmarks we use for testing HTTPie's speed and the infrastructure to automate this testing accross versions.
 
 ## Usage
 
 Ensure the following requirements are satisfied:
+
 - Python 3.7+
 - `pyperf`
 
 Then, run the `extras/benchmarks/run.py`:
+
 ```
 $ python extras/profiling/run.py
 ```
 
-Without any options, this command will initially create
-an isolated environment and install `httpie` from the
-latest commit. Then it will create a second environment
-with the `master` of the current repository and run the
-benchmarks on both of them. It will compare the results
-and print it as a markdown table:

-| Geometric mean                         | (ref)  | 1.10x faster         |

-If your `master` branch is not up-to-date, you can get
-a fresh clone by passing `--fresh` option. This way,
-the benchmark runner will clone the `httpie/httpie` repo
-from `GitHub` and use it as the baseline.

+You can customize these branches by passing `--local-repo`/`--target-branch`, and customize the repos by passing `--local-repo`/`--target-repo` (can
+either take a URL or a path).
