 * [InnerSource Hackathon](/patterns/1-initial/innersource-hackathon.md) - *In a company, initially only InnerSource enthusiasts are interested and practicing InnerSource during the early stages of InnerSource adoption; not all engineering teams are willing or have enough time and resources to adopt InnerSource. In this scenario, it is good to provide a safe space to try and adopt InnerSource through an InnerSource Hackathon event within the company.*
 * [Managing Capacity for Reviewing Contributions](/patterns/1-initial/capacity-for-contributions.md) - *Reviewing InnerSource contributions takes time and effort. This should be reflected in capacity planning, especially for larger contributions. Expectations and available capacity should be transparent so that contributors understand when their contributions will be reviewed and, if accepted, released.*
 * [InnerSource Ambassadors](/patterns/1-initial/innersource-ambassador.md) - *When driving InnerSource adoption through a large, decentralized organization it is hard to understand and address the local challenges that come up in different departments and regions. Local volunteers, called InnerSource Ambassadors, provide localized support by promoting InnerSource principles and acting as a communication bridge between their teams and the ISPO.*
+* [Circle Communities](/patterns/1-initial/circle-communities.md) - *InnerSource adoption is slow in organizations due to limited understanding, engagement, and contextual relevance. Circle Communities address this by fostering synchronous conversations that build connections, close knowledge gaps, and cultivate collaboration and continuous learning.*
