+# BAG (BAG AMS Generator) Primitives Library for [SKY130](https://github.com/google/skywater-pdk)
+
+This repository contains the required primitives to use BAG3 framework with
+[the Google skywater-pdk, a fully open source, manufacturable PDK for
+SkyWater's 130nm (SKY13) process node](https://github.com/google/skywater-pdk).
+
+When combined with appropriate generator code, the primitives enables the
+creation of analog integrated circuits that are manufacturable at
+[SkyWater Technologies](https://www.skywatertechnology.com/) commercially or
+through programs like
+[Google's no-cost MPW shuttle program for open source designs, done in collaboration with efabless](https://efabless.com/open_shuttle_program).
+
+## What is BAG?
+
+[BAG AMS Generator (BAG)](https://github.com/ucb-art/bag) is the 3rd generation
+of the Berkeley Analog Generator framework (see also
+[BAG v2 framework](https://github.com/ucb-art/bag)).
+
+
+## License
+
+To enable wide compatibility with the existing BAG ecosystem, this repository
+is dual-licensed. It is available to you under your choice of the
+[the Apache 2.0 license](LICENSE) or a [3 clause BSD style](LICENSE.alternative).

+Google Open Source Community Guidelines
+---------------------------------------
+
+.. community_guidelines_text
+
+At Google, we recognize and celebrate the creativity and collaboration
+of open source contributors and the diversity of skills, experiences,
+cultures, and opinions they bring to the projects and communities they
+participate in.
+
+Every one of Google's open source projects and communities are inclusive
+environments, based on treating all individuals respectfully, regardless
+of gender identity and expression, sexual orientation, disabilities,
+neurodiversity, physical appearance, body size, ethnicity, nationality,
+race, age, religion, or similar personal characteristic.
+
+We value diverse opinions, but we value respectful behavior more.
+
+Respectful behavior includes:
+
+- Being considerate, kind, constructive, and helpful.
+- Not engaging in demeaning, discriminatory, harassing, hateful,
+ sexualized, or physically threatening behavior, speech, and imagery.
+- Not engaging in unwanted physical contact.
+
+Some Google open source projects
+`may adopt <https://opensource.google/docs/releasing/preparing/#conduct>`__
+an explicit project code of conduct, which may have additional detailed
+expectations for participants. Most of those projects will use our
+`modified Contributor Covenant <https://opensource.google/docs/releasing/template/CODE_OF_CONDUCT/>`__.
+
+Resolve peacefully
+~~~~~~~~~~~~~~~~~~
+
+We do not believe that all conflict is necessarily bad; healthy debate
+and disagreement often yields positive results. However, it is never
+okay to be disrespectful.
+
+If you see someone behaving disrespectfully, you are encouraged to
+address the behavior directly with those involved. Many issues can be
+resolved quickly and easily, and this gives people more control over the
+outcome of their dispute. If you are unable to resolve the matter for
+any reason, or if the behavior is threatening or harassing, report it.
+We are dedicated to providing an environment where participants feel
+welcome and safe.
+
+Reporting problems
+~~~~~~~~~~~~~~~~~~
+
+Some Google open source projects may adopt a project-specific code of
+conduct. In those cases, a Google employee will be identified as the
+Project Steward, who will receive and handle reports of code of conduct
+violations. In the event that a project hasn’t identified a Project
+Steward, you can report problems by emailing opensource@google.com.
+
+We will investigate every complaint, but you may not receive a direct
+response. We will use our discretion in determining when and how to
+follow up on reported incidents, which may range from not taking action
+to permanent expulsion from the project and project-sponsored spaces. We
+will notify the accused of the report and provide them an opportunity to
+discuss it before any action is taken. The identity of the reporter will
+be omitted from the details of the report supplied to the accused. In
+potentially harmful situations, such as ongoing harassment or threats to
+anyone's safety, we may take action without notice.
+
+*This document was adapted from the*
+`IndieWeb Code of Conduct <https://indieweb.org/code-of-conduct>`_

+How to Contribute
+=================
+
+We'd love to accept your patches and contributions to this project.
+There are just a few small guidelines you need to follow.
+
+Contributor License Agreement
+-----------------------------
+
+Contributions to this project must be accompanied by a Contributor
+License Agreement. You (or your employer) retain the copyright to your
+contribution; this simply gives us permission to use and redistribute
+your contributions as part of the project. Head over to
+https://cla.developers.google.com/ to see your current agreements on
+file or to sign a new one.
+
+You generally only need to submit a CLA once, so if you've already
+submitted one (even if it was for a different project), you probably
+don't need to do it again.
+
+Code reviews
+------------
+
+All submissions, including submissions by project members, require
+review. We use GitHub pull requests for this purpose. Consult `GitHub
+Help <https://help.github.com/articles/about-pull-requests/>`__ for more
+information on using pull requests.
+
+Community Guidelines
+--------------------
+
+This project follows `Google's Open Source Community
+Guidelines <https://opensource.google/conduct/>`__.
