+## Installing specific dependency groups
+
+In some cases, like when you'll be using the configuration bootstrapping script, you might need to install extra dependencies that are 
+not necessary for the bot project to function.
+These dependency are put in a separate optional group likewise:
+
+```text
+[tool.poetry.group.group-name]
+...
+[tool.poetry.group.group-name.dependencies]
+pytest = "^6.0.0"
+pytest-mock = "*"
+```
+
+To install them, you simply need to run the following command
+---
+
+```shell
+$ poetry install --only {{group-name}}
+```
