 Windows may complain about security due to code not being signed, this will be completed at a later stage. If you downloaded from this repo, you are good to continue the set up. 
 
 **Integrations**
-  - If you use Python plugins:
-    - Install [Python3](https://www.python.org/downloads/), download `.exe` installer.
+  - Python plugins:
+    - Once a Python plugin has been detected at start up, you will be prompted to either select the location or allow Python 3.9.1 to automatic download and install. 
     - Add Python to `%PATH%` or set it in flow's settings.
-    - Use `pip` to install `flowlauncher`, cmd in `pip install flowlauncher`.
+    - Use `pip` to install `flowlauncher`, open cmd and type `pip install flowlauncher`.
+    - The Python plugin may require additional modules to be installed, please ensure you check by visiting the plugin's website via `pm install` + plugin name, go to context menu and select `Open website`. 
     - Start to launch your Python plugins.
   - Flow searches files and contents via Windows Index Search, to use Everything, download the plugin [here](https://github.com/Flow-Launcher/Flow.Launcher.Plugin.Everything/releases/latest).
 
 **Usage**
 - Open flow's search window: <kbd>Alt</kbd>+<kbd>Space</kbd> is the default hotkey.
-- Open context menu: <kbd>Ctrl</kbd>+<kbd>O</kbd>/<kbd>Shift</kbd>+<kbd>Enter</kbd>.
+- Search programs, bookmarks and control panel items with acronyms eg. `gk` or `gp` for GitKraken Preview; fuzzy search eg. `code` or `vis` for Visual Studio Code.
+- Open context menu: on the selected result, press <kbd>Ctrl</kbd>+<kbd>O</kbd>/<kbd>Shift</kbd>+<kbd>Enter</kbd>.
 - Cancel/Return to previous screen: <kbd>Esc</kbd>.
 - Install/Uninstall/Update plugins: in the search window, type `pm install`/`pm uninstall`/`pm update` + the plugin name.
+- Press `F5` while in the query window to reload all plugin data.
 - Saved user settings are located:
   - If using roaming: `%APPDATA%\FlowLauncher`
   - If using portable, by default: `%localappdata%\FlowLauncher\app-<VersionOfYourFlowLauncher>\UserData`
