+# Maturity Assessment for Apache DevLake™
+
+The goals of this maturity model are to describe how Apache projects operate 
in a concise and high-level way, and to provide a basic framework that projects 
may choose to use to evaluate themselves.
+
+More details can be found 
[here](https://community.apache.org/apache-way/apache-project-maturity-model.html).
+
+## Status of this assessment
+
+This assessment is being evaluated during DevLake's graduation from Apache 
Incubator to a top-level Apache project.
+
+## Maturity model assessment
+
+The following table is filled according to the [Apache Maturity 
Model](https://community.apache.org/apache-way/apache-project-maturity-model.html).
 Mentors and community members are welcome to comment and modify it.

the PPMC on [email protected] and [email protected] with at
