+# Tekton Design Principles
+
+## Reusability
+- Existing features should be reused when possible instead of adding new ones.
+- Prefer providing a solution in the Catalog when possible to adding a feature.
+- In design docs, discuss how a new feature affects the reusability of Tasks and Pipelines.
+
+## Simplicity 
+- Tekton should contain only the bare minimum and simplest features needed to meet the largest number of CI/CD use cases.
+- Prefer a [simple](https://www.infoq.com/presentations/Simple-Made-Easy/) solution that solves most use cases to a complex solution that solves all use cases (can be revisited later).
+- New features should be consistent with existing components, in structure and behavior, to make learnability, trialability and adoption easy.
+- Any new feature should have been previously discussed and agreed upon in a [Tekton Enhancement Proposal](https://github.com/tektoncd/community/tree/master/teps). 
+- In design docs, demonstrate that the proposed feature is absolutely necessary. What’s the current experience without the feature and how challenging is it?
+
+## Flexibility
+- Tekton has a ton of flexibility, which means a lot of things can be implemented by some kind of plugin. When considering adding something to Tekton itself, we should consider and exhaust all opportunities to implement it using one of the existing plugin mechanisms.
+- Specific choices (kubernetes, github) should be implemented at the step or DSL levels by the users, not at the Task or Pipeline levels to keep Tekton flexible. 
+- When a specific choice (tool, resource, language, etc) has to be made at the Task or Pipeline levels, users should be able to extend it to add their own choices.
+- When a specific choice is in consideration, evaluate what we’re coupling Tekton to and what it means in terms of support and maintenance.
+- Avoid implementing templating logic; prefer variable replacement.
+- Avoid implementing our own expression syntax; when required prefer existing languages which are widely used and include supporting development tools.
+
+## Conformance
+- Tekton features should work as the user expects in varied environment setup.
+- Tekton should not contain kubernetes-specific features in the API as much as possible. When kubernetes-specific features have to be added, they should be explicitly called out in the design docs and consider shunting them together into a section of the API, such as podTemplate.  
+- In design docs, discuss how the proposal affects conformance.
