+These instructions should also apply to IntelliJ IDEA with the Python plugin installed although the location of Python SDK settings will be different.

+
+In order to take full advantage of PyCharm's smart assistance features, such as code completion, PyCharm needs to have access to the libraries used in your code.
+The following instructions will guide you through setting up your local environment to have access our `sr.robot3` API.
+
+1. Open your robot code project in PyCharm.
+2. Head to `File` &rarr; `Settings` or `PyCharm` &rarr; `Preferences` on a Mac.

+3. Select `Project` &rarr; `Project Interpreter` from the list on the left.
+4. Click the `+` symbol at the top of the packages list to install a new library.

+5. Search for `sr.robot3` then click `Install Package`

+If this results in an error, try selecting the `Install to user's site packages directory` checkbox at the bottom of the dialog and try again.
+6. All done. You can now close the Settings window.
+
+You should now be able to use code completion and have quick access documentation by pressing <kbd>Ctrl</kbd><kbd>Q</kbd> (or <kbd>⌃</kbd><kbd>J</kbd> on a Mac)
