+
+Activepieces utilizes Role-Based Access Control (RBAC) for managing permissions within projects. Each project consists of multiple flows and users, with each user assigned specific roles that define their actions within the project.
+
+## Default Roles
+
+Activepieces comes with four standard roles out of the box. The table below shows the permissions for each role:
+
+| Permission | Admin | Editor | Operator | Viewer |
+|------------|:-----:|:------:|:--------:|:------:|
+| **Flows** |||||
+| View Flows | ✓ | ✓ | ✓ | ✓ |
+| Edit Flows | ✓ | ✓ | | |
+| Publish / Toggle Flows | ✓ | ✓ | ✓ | |
+| **Runs** |||||
+| View Runs | ✓ | ✓ | ✓ | ✓ |
+| Retry Runs | ✓ | ✓ | ✓ | |
+| **Connections** |||||
+| View Connections | ✓ | ✓ | ✓ | ✓ |
+| Edit Connections | ✓ | ✓ | ✓ | |
+| **Team** |||||
+| View Project Members | ✓ | ✓ | ✓ | ✓ |
+| Add/Remove Project Members | ✓ | | | |
+| **Git Sync**    |      |        |      |      |
+| Configure Git Repo      | ✓    |        |      |      |
+| Pull Flows from Git     | ✓    |        |      |      |
+| Push Flows to Git       | ✓    |        |      |      |
+
+## Custom Roles
+
+If the default roles don't fit your needs, you can create custom roles with specific permissions.
+
+<Steps>
+  <Step title="Navigate to Project Roles">
+    Go to **Platform Admin** → **Security** → **Project Roles**
+  </Step>
+  <Step title="Create a New Role">
+    Click **Create Role** and give it a name
+  </Step>
+  <Step title="Configure Permissions">
+    Select the specific permissions you want to grant to this role
+  </Step>
+</Steps>
+
+<Tip>
+Custom roles are useful when you need fine-grained control, such as allowing users to view and retry runs without being able to edit flows.
