+### `enable-networking`
+
+Controls whether the CommandAPI's plugin messaging functionality is enabled.
+
+By default, this is set to `false`, and the CommandAPI will not attempt to to send or receive any plugin messages. At the moment, the only intended usecase for enabling networking is to allow [command requirements](../create-commands/requirements.md) to work on a [Velocity](../velocity/intro.md#updating-requirements) proxy server.
+
+**Default value**
+
+```yaml
+enable-networking: false
+```
+
+**Example value**
+
+```yaml
+enable-networking: true
+```
+
+### `make-networking-exceptions-warnings`
+
+Controls whether the CommandAPI will throw an exception or log a warning when networking errors occur.
+
+By default, this is set to `false`, so the CommandAPI will throw an exception when receiving malformed packets or if it tries to send a packet but cannot. If `true`, these problems will be logged as a warning, which reduces the length in the log by omitting the stack trace. Additionally, these warnings will be hidden completely if [`silent-logs`](#silent-logs) is also `true`.
+
+**Default value**
+
+```yaml
+make-networking-exceptions-warnings: false
+```
+
+**Example value**
+
+```yaml
+make-networking-exceptions-warnings: true
+```
+
 ### `plugins-to-convert`
 
 Controls the list of plugins to process for command conversion. See [Command conversion](command-conversion/conversion) for more information.
