 In this example, we set `/home/cas/media/Downloads` as the download folder and we map the folder `/home/cas/media/Comics` to `/RF` and `/home/cas/media/Comics-2` to `/RF-2`. In Kapowarr, you'd then add `/RF` and `/RF-2` as root folders.
 
 ## Manual Install
-Coming soon
+=== "Ubuntu"
+	We can install by cloning the github code to a local directory and then running.  
+
+	### Pre-requisites
+	Before we can install, we need to make sure we have python3 and pip installed.
+
+	We can check the version of Python that is currently installed by using:
+	```bash
+	python --version
+	```
+	If you have more than one version of python installed, you may need to use:
+	```bash
+	python3 --version
+	```
+	If the version is not 3.7 or above, we can install version 3.8 using the deadsnakes PPA as follows:
+	```bash
+	sudo apt-get install software-properties-common
+	sudo add-apt-repository ppa:deadsnakes/ppa
+	sudo apt-get update
+	sudo apt-get install python3.8
+	```
+	Now we just want to make sure we have pip installed for python3:
+	```bash
+	sudo apt-get install python3-pip
+	```
+
+	### Installing Kapowarr
+	First of all, we need to clone the git repository:
+	```bash
+	git clone https://github.com/Casvt/Kapowarr /opt/Kapowarr
+	```
+	Then we need to install the requirements:
+	```bash
+	pip3 install -r requirements.txt
+	```
+	Now, we can run the application by using
+	```bash
+	python3 /opt/Kapowarr/Kapowarr.py
+	```
+	note: If you have to run the pip command with sudo, you will need to run the python3 command with sudo as well
+
+	By default the application listens on port 5656 - so you can go to http://localhost:5656 to start using it.  To stop the application, just hit ctrl-c
+
+	### Setting the application to run as a service
+	If you want Kapowarr to run as an application, we can set it up as follows:
+	```bash
+	sudo nano Kapowarr.sh
+	```
+	In the file editor, enter the following:
+	```bash
+	#!/bin/sh
+
+	### BEGIN INIT INFO
+	# Provides:          Kapowarr
+	# Required-Start:    $remote_fs $syslog
+	# Required-Stop:     $remote_fs $syslog
+	# Default-Start:     2 3 4 5
+	# Default-Stop:      0 1 6
+	# Short-Description: Put a short description of the service here
+	# Description:       Put a long description of the service here
+	### END INIT INFO
+
+	# Change the next 3 lines to suit where you install your script and what you want to call it
+	DIR=/opt/Kapowarr
+	DAEMON=/usr/bin/python3 $DIR/Kapowarr.py
+	DAEMON_NAME=Kapowarr
+
+	# Add any command line options for your daemon here
+	DAEMON_OPTS=""
+
+	# This next line determines what user the script runs as.
+	# Root generally not recommended but necessary if you are using the Raspberry Pi GPIO from Python.
+	DAEMON_USER=pi
+
+	# The process ID of the script when it runs is stored here:
+	PIDFILE=/var/run/$DAEMON_NAME.pid
+
+	. /lib/lsb/init-functions
+
+	do_start () {
+		log_daemon_msg "Starting system $DAEMON_NAME daemon"
+		start-stop-daemon --start --background --pidfile $PIDFILE --make-pidfile --user $DAEMON_USER --chuid $DAEMON_USER --startas $DAEMON -- $DAEMON_OPTS
+		log_end_msg $?
+	}
+	do_stop () {
+		log_daemon_msg "Stopping system $DAEMON_NAME daemon"
+		start-stop-daemon --stop --pidfile $PIDFILE --retry 10
+		log_end_msg $?
+	}
+
+	case "$1" in
+
+		start|stop)
+			do_${1}
+			;;
+
+		restart|reload|force-reload)
+			do_stop
+			do_start
+			;;
+
+		status)
+			status_of_proc "$DAEMON_NAME" "$DAEMON" && exit 0 || exit $?
+			;;
+
+		*)
+			echo "Usage: /etc/init.d/$DAEMON_NAME {start|stop|restart|status}"
+			exit 1
+			;;
+
+	esac
+	exit 0
+	```
+	To close and save the file, press ctrl-x, then y and enter.
+
+	Now we just move this file to the init.d folder, make it executable and enable it as a service:
+	```bash
+	sudo mv Kapowarr.sh /etc/init.d/Kapowarr.sh
+	sudo chmod 755 /etc/init.d/Kapowarr.sh
+	sudo update-rc.d Kapowarr.sh defaults
+	```
+	Then we should be able to start and stop the application with:
+	```bash
+	sudo systemctl start Kapowarr.service
+	```
+	and 
+	```bash
+	sudo systemctl stop Kapowarr.service
+	```
