+= Commenting on fields and enums
+
+The reference documentation of OSI is created using _Doxygen_.
+The content of the reference documentation is generated from comments in the `.proto` files.
+Follow these steps when creating comments on fields and enums to keep the documentation style consistent.
+
+**Prerequisites**
+
+* You have created a field or enum.
+
+**Steps**
+
+. Add a description to the field or enum followed by an empty comment line.
+. Add the unit of the field using the format `Unit: UNIT` followed by an empty comment line.
+. Optionally, add notes using the keyword `\note`.
+. Optionally, add literary references to the comments.
+The list of references starts with `\par References:` followed by the references.
+Every reference starts on a new line.
+Every reference begins with a reference number in the format `[n]`.
+Every reference ends with `\n`, except the last reference.
+. Optionally, add rules encapsulated between `\rules` and `\endrules`.
+
+**Example**
+
+----
+// \brief The conditions of the environment.
+//
+// \image html EnvironmentalConditions.svg
+//
+// Definition of light, weather conditions and other environmental conditions.
+//
+// \note These conditions apply locally around the host vehicle.

+= Guidelines for contributions
+
+Commit guidelines ensure the transparency and intelligibility of the commit history.
+ASAM OSI enforces the following commit guidelines:
+
+- Prefer small atomic commits over large ones that do many things.
+- Do not mix refactoring and new features.
+- Do not mix style changes, for example indentation changes, with actual code changes.
+- If you add new messages to a *.proto file, add appropriate documentation as well.
+- Run the unit tests for comment compliance to check if you followed the correct syntax guidelines for *.proto files.
+- Follow the guidelines for commit messages.
+- Sign off commit messages.
+- Name branches meaningfully and consistently.
+- If a commit contains work-in-progress, add the _WIP_ label to the commit message.

+= Guidelines for creating literary references
+
+When citing literature in the reference documentation, adhere to the following guidelines:
+
+* All sources shall be primary sources. Sources like Wikipedia are not allowed.
+* OSI uses _APA style_ references from the American Psychological Association.
+* In the text, sources are cited using numbers in brackets.
+* In the references list, the number in brackets is resolved to a full citation.
+* Titles shall be written in italic, using `title`.
+* If the list contains more than one entry, add `\n` at the end of the line to create a line break within the list.
+* Author names shall be written as , .
+* Editor names shall be written as .
+* Page numbers are optional and may be used with long texts or for referencing specific sections.
+
+**Templates**
+
+Use the following templates for creating properly styled references:
+
+Compilation::
+[source]
+----
+, , & . (). Contribution in a compilation title. . . . . . . .

+How could we make this more maintainable?
+
+Discuss in person for more detailed points::
+Online comments are useful for focused technical questions.
+In case of more detailed discussions, it will often be more productive to discuss in person.
+
+Explain yourself::
+Sometimes it is best to both ask if there is a better alternative and at the same time justify why a problem in the code is worth fixing.
+Criticism without explanation can appear confrontational.
+
+Make it about the code::
+It is easy to take notes from code reviews personally, especially if we take pride in our work.
+It is best to make discussions about the code than about the developer.
+
+Suggest importance of fixes::
+When offering many suggestions at once, clarify that not all of them need to be acted upon at once.
+Indicate the importance of your suggestions.
+This allows developers to improve their work incrementally.
+
+Take the developer’s opinion into consideration::
+Imposing a particular design choice out of personal preferences and without a real explanation will incentivize the developer to be passive instead of active and creative.
+
+Do not re-write, remove or re-do all the work::
+Sometimes, it appears easier to re-do the work yourself, thereby discarding the work of the developer.
+This can give the impression that the work of the developer is worthless.
+It also adds additional work for the reviewer who effectively takes responsibility for the code.
+
+Consider the person you are reviewing::
+Developers are human beings.
+Consider their personality and experience when reviewing their code.
+
+Avoid confrontational and authoritative language::
+The way we communicate has an impact on the receiver.
+Consider these two statements to communicate about a problem in the code:
+The statement “This operation is wrong, please fix it.” is confrontational and authoritative.
+Instead, explain the specific error and ask the developer to review the code again.

+Contributing to OSI projects requires agreeing to the Developer Certificate of Origin (DCO).
+Contributors agree to the DCO by adding a ``Signed-off-by`` statement to the commit message.
+
+----
+Signed-off-by: Firstname Lastname
+----
+
+If a commit does not include the ``Signed-off-by`` statement, this commit cannot be merged into the master branch.
+
+To add a sign-off statement to a commit add ``-s`` or ``--signoff`` to the commit command:
+

+= Guidelines for writing commit messages
+
+Apart from a sign-off message, OSI requires commit messages to follow a specific format.
+This format enables others to understand the motivation behind your commits more easily.
+OSI enforces these requirements only for commits to protected branches.
+However, you should follow these guidelines always to help others to understand your commits.
+
+Commit messages shall have the following structure:
+
+[source]
+----
+[optional scope]:
+
+[optional body]
+
+[optional footer(s)]
+----
+
+Commits can have one of the following types:
+
+fix::
+Change fixes an error.
+Such changes usually correspond to a PATCH release.
+
+feat::
+Change introduces a new feature.
+If the change is backwards compatible, it corresponds to a MINOR release.
+If the change is not backwards compatible, it corresponds to a MAJOR release.
+
+style::
+Change affects only the style but not the meaning of the code.
+Examples include white-space changes or code formatting.
+
+build::
+Change affects the building components.
+Examples include changes to the CI pipeline or the project version.
+
+The scope indicates which part of OSI is affected by the commit.
+With OSI, commits can have one of the following scopes:
+
+code::
+Change affects the OSI code.
+
+inlinedocs::
+Change affects the inline documentation.
+
+docs::
+Change affects the accompanying documentation.
+
+The description gives a concise summary of the change.
+The description shall adhere to the following rules:
+
+- Use imperative mode and present tense to indicate what happens, when the change is applied.
+- Do not capitalize the first letter.
+- Do not end the description with a full stop.
+
+The optional body contains information about the motivation behind the change.
+This includes references to Github issues by ID.
+Github uses these IDs to create links between the issues and the commit history.
+
+The optional footer contains a note, if the changes are breaking backwards compatibility.
+Such a note starts with `BREAKING CHANGES:` followed by a concise description of what this change breaks.
+
+The following example shows a commit message meeting all requirements:
+
+[source]
+----
+feat(model): Prevent empty StopTriggers
+
+refers to #23
+
+BREAKING CHANGES: StopTrigger can no longer be empty
+Signed-off-by: Max Mustermann
