As a Spanish speaker who can read Portuguese, the docs seem well written and translated. Style consideration, words like "pipeline, issue, branch, Bugs, pull request" are left in English, but I agree with this choice. Translating these terms could be possible but might come at the cost of exact communication. Native Portuguese speakers can of course chime in who would have a more educated opinion. Offering my feedback as there may not be any current contributors who read Portuguese (at time of writing no contributors have location Brazil or Portugal on their profiles).

@polong-lin (our doc lead) to help review this change and our multi-lingual support.

i've just discovered the adk-docs repo, it would be nice to have some reference to it here.
