+### Branches
+
+When creating branches, we follow the following pattern:
+
+`[type]/[area]/[individual name]`
+
+- `type`: What is the purpose of your changes? Currently we are using the following tags
+  - feature: for implementing new features
+  - fix: for bugfixes
+  - hotfix: for urgent fixes such as security vulnerabilities and more important bugs that severely affect the usability of our application
+  - refactor: for changes that only improve the source code and have little or no impact on the functionality of Kioku
+  - test: for everything concerning testing
+  - deployment: for all deployment topics
+  - docs: for updating the docs
+- `area`: Which area of the application do the changes affect? If none or both apply to your changes, simply leave it out.
+  - frontend
+  - backend
+- `individual name`: This is where you should try to summarize your changes as short and precise as possible. If you need several words, separate them with a dash and write everything in lower case.
+
+### Commits
+
+When committing changes, please write your messages according to the following convention:
+
+This commit will `Your commit message`
+
+Write the first letter of your message in upper case and the rest in lower case.
+
+### Pull requests
+
+When you open a pull request, remember to label it and link the corresponding issue. Pull requests should always concern only one specific subject. Please use the template and fill in the required information.
+
+# Backend
+
+If you make changes to the backend, please keep the following points in mind.
+
+- Export new proto definitions with every change via `make proto` in the corresponding service directory
+- Make yourself familiar with the `helper` and `converter` packages of the project as they contain standards for serializing/deserializing objects, error definition, JWT handling and ID naming
+- Document API changes in the `bruno` project inside `/backend/api-documentation`
+
+If you are not familiar with any of these points, take a look at our [backend documentation](./docs/backend_development.md) or ask us for help.
+# Frontend
+
+If you make changes to the frontend, please ensure the following points.
+
+- Please run Prettier before commiting changes.
+- Stories should be available for each component and its different variants.
+- A corresponding translation in English and German should be provided for each text. If you do not speak German, we will support you with the translation.
+
+If you are not familiar with any of these points, take a look at our [frontend documentation](./docs/frontend_development.md) or ask us for help.
