+# Configuration
+
+Icinga DB Web is configured via the web interface. Below you will find an overview of the necessary settings.
+
+## Database Configuration
+
+Connection configuration for the database to which Icinga DB synchronizes monitoring data.
+
+1. Create a new resource for the Icinga DB database via the `Configuration → Application → Resources` menu.
+
+2. Configure the resource you just created as the database connection for the Icinga DB Web module using the
+   `Configuration → Modules → icingadb → Database` menu.
+
+## Redis Configuration
+
+Connection configuration for the Redis server where Icinga 2 writes check results.
+This data is used to display the latest state information in Icinga DB Web.
+
+1. Configure the connection to the Redis server through the `Configuration → Modules → icingadb → Redis` menu.
+
+!!! info
+
+    If you are running a high-availability Icinga 2 setup,
+    also configure the secondary master's Redis connection details.
+    Icinga DB Web then uses this connection if the primary one is not available.
+
+## Command Transport Configuration
+
+In order to acknowledge problems, force checks, schedule downtimes, etc.,
+Icinga DB Web needs access to the Icinga 2 API.
+For this you need an `ApiUser` object with at least the following permissions on the Icinga 2 side:
+
+* `actions/*`
+* `objects/query/*`
+* `objects/modify/*`
+* `status/query`
+
+!!! tip
+
+    For single-node setups it is recommended to manage API credentials in the `/etc/icinga2/conf.d/api-users.conf` file.
+    If you are running a high-availability Icinga 2 setup, please manage the credentials in the master zone.
+
+1. Please add the following Icinga 2 configuration and change the password accordingly:
+   ```
+   object ApiUser "icingadb-web" {
+       password = "CHANGEME"
+       permissions = [ "actions/*", "objects/modify/*", "objects/query/*", "status/query" ]
+   }
+   ```
+2. Restart Icinga 2 for these changes to take effect.
+3. Then configure a command transport for Icinga DB Web
+   using the credentials you just created via the `Configuration → Modules → icingadb → Command Transports` menu.
+
+!!! info
+
+    If you are running a high-availability Icinga 2 setup,
+    also configure the secondary master's API command transport.
+    Icinga DB Web then uses this transport if the primary one is not available.
+
+## Security
+
+To grant users permissions to run commands and restrict them to specific views,
+see the [Security](04-Security.md) documentation for the necessary steps.
