+The CoCom panel is focused on analyzing source code information obtained
+from Graal. [Graal](https://github.com/chaoss/grimoirelab-graal) is a tool
+which uses a wide range of Backends for specific tasks, one of them
+being **`Code Complexity(CoCom)`** which provides source code related
+information such as Code Complexity, Lines of Code, Functions and many
+more from a given software repository.
+
+## Metrics
+From left to right and top to bottom, some of the metrics provided are:
+
+* **Repositories Overview**: Overview of all the repositories and overall metrics 
+  per project.
+* **Evolution: Code Complexity & Functions**: Evolution of Code Complexity and 
+  Functions over a given period of time.
+* **Evolution: LOC & Comments**: Evolution of Lines of Code and Comment Lines
+  over a given period of time.
+* **All Files: Code complexity, LOC and ratios**: Shows metrics such as Code
+  Complexity, LOC, Functions, and others for every file in a project. It can be
+  delegated for a module with the help of the Selector.
+
+Additionally, the visualizations can be delegated with the help of Selector at the Top(left);
+which provides filters such as **`Module Path`**, **`Interval`**, **`Repository`** and many more
+for specific purposes.
