+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at **t.fitschen (AT) indiscale.com**,
+**d.hornung (AT) indiscale.com**, **a.schlemmer (AT) indiscale.com**, or
+**h.tomwoerden (AT) indiscale.com**.  All complaints will be
+reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+
+## Code of Conduct
+
+By participating, you are expected to uphold our [Code of Conduct](CODE_OF_CONDUCT.md).
+
+## How to Contribute
+
+* You found a bug, have a question, or want to request a feature? Please file
+  a Gitlab issue.
+* You want to contribute code or write documentation? There is no standardized
+  way to contribute code yet. Please contact us at <info@indiscale.com> if
+  there has not been any prior contact.
+
+## Merge Requests and Code Review
+
+Please, prepare your MR for a review: Be sure to write a summary section and a
+focus section. The summary should summarize what your MR is about. The focus
+should point the reviewer to the most important code changes.
+
+Also, create gitlab comments for the reviewer. They should guide the
+reviewer through the changes, explain your changes and also point out open
+questions.
+
+For further good practices have a look at
+[our review guidelines](https://gitlab.com/caosdb/caosdb/-/blob/dev/REVIEW_GUIDELINES.md).

+# How to Develop the CaosDB GRPC API
+
+Make yourself familiar with
+[protobuf](https://developers.google.com/protocol-buffers/) and
+[grpc](https://grpc.io/).
+
+## Formatting
+
+We use
+[clang-format-11](https://releases.llvm.org/11.0.0/tools/clang/docs/ClangFormat.html)
+or later for formatting of `*.proto` files. Run `clang-format -i $(find proto/
+-type f -iname "*.proto")` to format all the files. The `.clang-format`
+contains all necessary configuration.
+
+## Linting
+
+We use [buf](https://docs.buf.build/) for linting. Run `buf lint`. The
+`buf.yaml` contains all necessary configuration.
+
+## Docs
+
+We use [cmake](https://cmake.org) as build tool for the documenation and
+generate the documentation with Sphinx and the Read-The-Docs theme.
+
+See [DEPENDENCIES.md](DEPENDENCIES.md).
+
+1. `cmake -B build`
+2. `cd build`
+3. `cmake --build . --target doc`
+
+Results are in `build/doc_out/index.html`.
+
+### Dependencies
+
+* cmake >= v3.14
+* protoc >= v3.12
+* all the pypi packages from `doc/requirements.txt`.

+# Release Guidelines for the CaosDB gRPC API
+
+This document specifies release guidelines in addition to the generel release
+guidelines of the CaosDB Project
+([RELEASE_GUIDELINES.md](https://gitlab.com/caosdb/caosdb/blob/dev/RELEASE_GUIDELINES.md))
+
+## General Prerequisites
+
+* All tests are passing.
+* FEATURES.md is up-to-date and a public API is being declared in that document.
+* CHANGELOG.md is up-to-date.
+* DEPENDENCIES.md is up-to-date.
+
+## Steps
+
+1. Create a release branch from the dev branch. This prevents further changes
+   to the code base and a never ending release process. Naming: `release-<VERSION>`
+
+2. Update CHANGELOG.md
+
+3. Check all general prerequisites.
+
+4. Prepare [CMakeLists.txt](./CMakeLists.txt): Check the `MAJOR`, `MINOR`, `PATCH`
+   version variables.
+
+5. Merge the release branch into the main branch.
+
+6. Tag the latest commit of the main branch with `v<VERSION>`.
+
+7. Delete the release branch.
+
+8. TODO...
