+# Codacy usage
+
+The **Codacy usage** dashboard provides an overview of how your organization is adopting Codacy. You can view and filter the list of repositories from your Git provider. It is also possible to filter, from repositories in Codacy, by gate and coverage information. You can also filter by selecting specific repositories or using [the segments that you have set up](segments.md).

+
+!!! important
+    Repositories not in Codacy is only available to GitHub accounts.
+
+To access the Codacy usage dashboard, select an organization from the top navigation bar and click on the **Codacy usage** tab at the top of the page.
+
+On the tab, if your Git provider is GitHub, you can view the percentage of repositories added to Codacy. Otherwise, you'll see the total number of repositories in Codacy.
+
+The Codacy usage dashboard includes the following sections to help you monitor Codacy adoption:
+
+- [Repositories](#repositories)
+- [Repositories evolution](#repositories-evolution)
+- [Merged pull requests](#merged-pull-requests)
+- [Top repositories](#top-repositories)
+
+!!! tip
+    In each section, you can click on the ellipsis icon in the top right corner to export that section's data to CSV or JSON.
+
+## Repositories
+
+This chart displays the distribution of repositories in Codacy and repositories not in Codacy. On the pie chart, around the number of repositories in Codacy, you can also see the distribution of repositories without gates, without coverage, without gates nor coverage, and with gates and coverage. You can click both on the pie chart and numbers to filter the results in the rest of the dashboard.

+## Merged pull requests
+
+This chart displays the number of pull requests merged in your repositories. Merged pull requests are distributed in two main categories - analyzed and not analyzed. Analyzed merged pull requests are shown in three different categories - passing gates, failing gates, and without gates. You can click on the chart to filter results in the dashboard.
+
+!!! note
+    Merged pull requests data is only from repositories that are in Codacy.

+
+## Top repositories
+
+This list displays maximum 10 repositories in your Git provider. Depending on the filters applied, the list will show repositories not in Codacy, repositories in Codacy, or repositories in Codacy grouped by a specific dimension, such as gates information and/or coverage information.
