 * [Internal Developer Platform](/patterns/1-initial/internal-developer-platform.md) - *As InnerSource adoption increases throughout an organisation, it is not unusual that project teams start to face inefficiencies in scaling their efforts due to fragmented tooling, environments, and workflows. An Internal Developer Platform (IDP) provides a way to tackle this type of challenges through a centralized, self-service system that standardizes development environments and integrates tools to enhance consistency, collaboration, and developer productivity.*
 * [Document Architecture Decisions](/patterns/1-initial/document-architecture-decisions.md) - *InnerSource contributors often face challenges in grasping the system's design rationale, which can result in misalignment between maintainers, contributors, and stakeholders — potentially discouraging participation. To enhance decision-making and transparency, we recommend capturing architecture decisions and their consequences in a lightweight, accessible format to streamline onboarding, clarify decisions, and support long-term project sustainability.*
 * [InnerSource Incentives and Disincentives](/patterns/1-initial/incentives-and-disincentives.md) - *Lack of awareness for incentives as well well as disincentives for InnerSource contribution decrease the chances of an InnerSource project receiving contributions; this is addressed by sharing a comprehensive list of potential incentives and disincentives.
+* [Walk the InnerSource talk](/patterns/1-initial/walk-the-innersource-talk.md) - *Teams across the organization are encouraged to adopt InnerSource principles such as working openly, sharing code, and collaborating transparently. But, if the team behind the InnerSource initiative doesn’t follow these practices themselves, it undermines credibility and adoption. Therefore, this team should lead by example: documenting their decisions as code, working in the open, and treating their work as an InnerSource project to build trust and show others how it’s done.*
