+=== "From source"
+
+    The first step is to install NGINX 1.20.2 using the repository of your choice or by [compiling it from source](https://docs.nginx.com/nginx/admin-guide/installing-nginx/installing-nginx-open-source/#compiling-and-installing-from-source).
+	
+	The target installation folder of BunkerWeb is located at `/opt/bunkerweb`, let's create it :
+	```shell
+	mkdir /opt/bunkerweb
+	```
+	
+	You can now clone the BunkerWeb project to the `/tmp` folder :
+	```shell
+	https://github.com/bunkerity/bunkerweb.git /tmp/bunkerweb
+	```
+	
+	BunkerWeb needs some dependencies to be compiled and install to `/opt/bunkerweb/deps`, the easiest way to it is by executing the [install.sh helper script](https://github.com/bunkerity/bunkerweb/blob/master/deps/install.sh) (please note that you will need to install additional packages which is not covered in this procedure and depends on your own system) :
+	```
+	mkdir /opt/bunkerweb/deps && \
+	/tmp/bunkerweb/deps/install.sh
+	```
+	
+	Additional Python dependencies needs to be installed into the `/opt/bunkerweb/deps/python` folder :
+	```shell
+	mkdir /opt/bunkerweb/deps/python && \
+	pip install --no-cache-dir --require-hashes --target /opt/bunkerweb/deps/python -r /tmp/bunkerweb/deps/requirements.txt && \
+	pip install --no-cache-dir --target /opt/bunkerweb/deps/python -r /tmp/bunkerweb/ui/requirements.txt
+	```
+	
+	Once dependencies had been installed, you can now copy the BunkerWeb sources to the target `/opt/bunkerweb` folder :
+	```shell
+	for src in api cli confs core gen helpers job lua misc utils ui settings.json VERSION linux/variables.env linux/bunkerweb-ui.env linux/scripts ; do
+		cp -r /tmp/bunkerweb/${src} /opt/bunkerweb
+	done
+	cp /opt/bunkerweb/helpers/bwcli /usr/local/bin
+	```
+	
+	Additional folders also need to be created :
+	```shell
+	mkdir /opt/bunkerweb/{configs,cache,plugins,tmp}
+	```
+	
+	Permissions needs to be fixed :
+	```shell
+	find /opt/bunkerweb -path /opt/bunkerweb/deps -prune -o -type f -exec chmod 0740 {} \; && \
+	find /opt/bunkerweb -path /opt/bunkerweb/deps -prune -o -type d -exec chmod 0750 {} \; && \
+	find /opt/bunkerweb/core/*/jobs/* -type f -exec chmod 750 {} \; && \
+	chmod 770 /opt/bunkerweb/cache /opt/bunkerweb/tmp && \
+	chmod 750 /opt/bunkerweb/gen/main.py /opt/bunkerweb/job/main.py /opt/bunkerweb/cli/main.py /opt/bunkerweb/helpers/*.sh /opt/bunkerweb/scripts/*.sh /usr/local/bin/bwcli /opt/bunkerweb/ui/main.py && \
+	chown -R root:nginx /opt/bunkerweb
+	```
+	
+	Last but not least, you will need to setup systemd unit files :
+	```shell
+	cp /tmp/bunkerweb/linux/*.service /etc/systemd/system && \
+	systemctl daemon-reload && \
+	systemctl stop nginx && \
+	systemctl disable nginx && \
+	systemctl enable bunkerweb && \
+	systemctl enable bunkerweb-ui
+	```
+
 Configuration of BunkerWeb is done by editing the `/opt/bunkerweb/variables.env` file :
 
 ```conf
