# Code Reviews

Code reviews are a central part of developing high-quality code for Chromium.
All changes must be reviewed.

The general patch, upload, and land process is covered in more detail in the
[contributing code](contributing.md) page.

# Code review policies

Ideally the reviewer is someone who is familiar with the area of code you are
touching. Any committer can review code, but an owner must provide a review
for each directory you are touching. If you have doubts, look at the git blame
for the file and the `OWNERS` files (see below).

To indicate a positive review, the reviewer provides a "Code-Review +1" in
Gerrit, also known as an LGTM ("Looks Good To Me"). A score of "-1" indicates
the change should not be submitted as-is.

If you have multiple reviewers, provide a message indicating what you expect
from each reviewer. Otherwise people might assume their input is not required
or waste time with redundant reviews.

[Respectful Code Reviews](cr_respect.md).

#### Expectations for all reviewers

  * Aim to provide some kind of actionable response within 24 hours of receipt
    (not counting weekends and holidays). This doesn't mean you have to do a
    complete review, but you should be able to give some initial feedback,
    request more time, or suggest another reviewer.
