+### Interactions Banner
+
+The "interactions banner" is generated based on your recent interactions and can be limited to only include mutuals (people that follows you and you follow them back).
+
+```shell
+php dynacover generate interactions
+```
+
+For mutuals only, include the `--mutuals` flag:
+
+```shell
+php dynacover generate interactions --mutuals
+```
+
+_Please notice that the "mutuals" version may have a limited set of results after filtering your latest interactions (~200 mentions)._
