+#### 1.4 Requirements
+Add all required (which need to be installed separately) python packages to a requirements.txt in the plugin directory so that the user can simply install all requirements for this plugin.
+
+For examples look at [the Telegram plugin](Telegram/requirements.txt)
+
+##### 1.4.1 Requirement installation
+To install the packages from the requirements.txt run
+`pip install -r /path/to/plugin/directory/requirements.txt`
+Or because for the current version (2.5) Python2 is required
+`pip2 install -r /path/to/plungin/directory/requirements.txt` will work for sure
