+## Background
+
+Serverless Workflow is a vendor-neutral, open-source, and fully community-driven ecosystem 
+for defining and running DSL-based workflows that target the serverless technology domain.
+
+This project is composed of:
+
+* [Specification](https://github.com/serverlessworkflow/specification/blob/main/specification.md) for defining DSL-based workflows.
+* [Developer SDKs](https://github.com/serverlessworkflow/specification#sdks) that provide support for many programming languages.
+* [Workflow runtimes](https://github.com/serverlessworkflow/specification#runtime) part of the project ecosystem, and support the execution of specification DSL.
+* [Developer tooling](https://github.com/serverlessworkflow/specification#Tooling) support for writing DSL-based workflows.
+
+Serverless Workflow was approved as a Cloud Native Sandbox level project on July 14, 2020.
+* [TOC review PDF](https://github.com/serverlessworkflow/specification/blob/main/community/presentations/2020-4-15-toc-pres.pdf).
+* [TOC sandbox proposal PR](https://github.com/cncf/toc/pull/376)
+
+## Alignment with Cloud Native
+
+Serverless Workflow project falls under the [CNCF "App Definition and Development"](https://landscape.cncf.io/card-mode?category=app-definition-and-development&grouping=category) category.
+
+Serverless Workflow is a member project of the [CNCF Serverless Working Group](https://github.com/cncf/wg-serverless).
+
+Serverless Workflow includes [Synapse](https://github.com/serverlessworkflow/synapse), a Kubernetes-native runtime engine for executing workflows that follows the 
+specification DSL definition.
+
+In addition, Serverless Workflow provides support for several other open-source projects and specifications in the cloud-native
+space:
+* CloudEvents
+* OpenAPI
+* AsyncAPI
+* GraphQL
+* OData
+* OAuth2
+
+## Year in Review
+
+This year was very exciting for the project. Some of the most notable accomplishments include:
+* Released specification version [0.6](https://github.com/serverlessworkflow/specification/releases/tag/v0.6)
+* Released specification version [0.7](https://github.com/serverlessworkflow/specification/releases/tag/v0.7)
+* Added [Synapse](https://github.com/serverlessworkflow/synapse), a Kubernetes-native runtime into our ecosystem
+* Added [sdk-net](https://github.com/serverlessworkflow/sdk-net), a .NET SDK into our ecosystem
+* Added [sdk-typescript](https://github.com/serverlessworkflow/sdk-typescript), a TypeScript SDK into our ecosystem
+* Added [two new project maintainers](https://github.com/serverlessworkflow/specification/blob/main/MAINTAINERS.md)
+
+From the community perspective we also had a good year:
+* Over 100 new followers on our [twitter channel](https://twitter.com/CNCFWorkflow).
+* Over 200 new stars on our [specification github repo](https://github.com/serverlessworkflow/specification).
+* Over 300 people attending our project office hours at 2021 KubeCon EU.
+* Presented at KubeCon EU 2021, KubeCon NA 2020, and KubeCon EU 2020
+* Mentioned as a key component of open-source microservices architectures at [InfoQ](https://www.infoq.com/articles/microservices-inside-out/)
+* Over 40 unique visitors per day on our [website](https://serverlessworkflow.io/)
+* Participated at the KubeCon EU 2021 BugBash
+
+## Annual Review Contents
+
+- **Include a link to your project’s devstats page. We will be looking for signs of consistent or increasing contribution activity.**
+
+Project [DevStats page](https://serverlessworkflow.devstats.cncf.io).
+The info for the span of one year shows:
+* Over 500 merged PRs
+* ~2000 commits by 30+ contributors
+* Community contributions from 10+ different companies
+* Over 100% increase to github stars compared to last year
+
+- **How many maintainers do you have, and which organizations are they from?** 
+
+Serverless Workflow currently has [5 project maintainers](https://github.com/serverlessworkflow/specification/blob/main/MAINTAINERS.md)
+  - Tihomir Surdilovic, Temporal Technologies
+  - Manuel Stein, Nokia Bell Labs
+  - Ricardo Zanini, Red Hat
+  - Charles d'Avernas , Neuroglia
+  - Antonio Mendoza Pérez, Independent
+
+
+- **What do you know about adoption, and how has this changed since your last review / since you joined Sandbox?**  
+
+Both the adoption and community interest has been steadily increasing over the course of the year.
+Most notable adoptions have been by:
+    - [Kogito](https://kogito.kie.org/), a Red Hat project automation runtime
+    - [Automatiko](https://automatiko.io/), a workflow automation runtime
+    - [Synapse](https://github.com/serverlessworkflow/synapse), a Kubernetes-based workflow runtime which has joined the Serverless Workflow ecosystem
+
+We also have a number of integrations that are currently work-in-progress which include
+integrations with [Temporal](https://temporal.io/).
+
+- **How has the project performed against its goals since the last review?**
+
+This is our first annual review since becoming a Sandbox project.
+We have surpassed all of our goals that we have set for this year.
+We have been able to not only surpass the goals of the main specifications,
+but also to go from just hosting a specification to creating
+an entire workflow ecosystem around it. This includes SDKs, Tooling (VSCode, IntelliJ),
+rumtimes (Synapse), etc.
+
+Over this year we were able to create a workflow DSL which is in our opinion
+at this time the most feature-rich and most powerful workflow DSL that exists.
+
+- **What are the current goals of the project?**
+
+Specification roadmap: https://github.com/serverlessworkflow/specification/tree/main/roadmap
+
+Our main goals for the project include:
+ - Release specification version 1.0 by end of 2021
+ - Add more SDKs in different languages
+ - Create a specification TCK
+ - Add integrations with different workflow DSLs
+ - Improve our community tooling support
+ - Add at least 2 more integrations with existing workflow runtimes by middle of 2022
+
+
+- **How can the CNCF help you achieve your upcoming goals?**
+ - Help us in promoting the project (Blogs, Twitter, KubeCon, etc)
+ - If feasible help our project via crowdfunding [here](https://crowdfunding.lfx.linuxfoundation.org/projects/serverless-workflow)
+ - Keep providing us with opportunities to have project office hours and talks at KubeCons
+
+
+- **Do you think that your project meets the criteria for incubation?**
+
+We believe we have made significant progress toward this goal and that the project is ready for incubation.
+We would like however to release Serverless Workflow specification v1.0 before starting this process
+(scheduled for end-of-year 2021).
