+# Pechatalka
+Site and chat-robot constructor for the Svoboda typography
+
+## Installation
+
+Before process any command think about **what it does** and whether the **paths** are specified correctly<br>
+
+
+### NGINX
+#### **Create the NGINX server**<br>
+You can copy an example of the server file from here: `/examples/nginx/pechatalka.conf`<br>
+<small><i>I prefer to rename nginx config files to domain names. For example: `pechatalka.kodorvan.tech`</i></small><br><br>
+1. `cd examples/nginx`<br>
+2. `sudo cp pechatalka.conf /etc/nginx/sites-avaiable/pechatalka.conf`<br>
+3. `sudo nvim /etc/nginx/sites-avaiable/pechatalka.conf`<br>
+<small>3.1 <i>Customize the file according to your requirements</i></small><br>
+4. `sudo ln -s /etc/nginx/sites-avaiable/pechatalka.conf /etc/nginx/sites-enabled/pechatalka.conf`<br>
+5. `sudo nginx -t`<br>
+<small>5.1 <i>Make sure that <b>NGINX does not throw errors</b>, otherwise proceed to step №3 or to the instructions for generate a TLS/SSL certificate</i></small><br>
+6. `sudo service nginx restart`<br>
+
+#### **Add mime-type recognition for javascript modules**<br>
+<small>Edit the file `/etc/nginx/mime.types`</small><br><br>
+**From:** `application/javascript js;`<br>
+**To:** `application/javascript js mjs;`
+
+#### **Generate a TLS/SSL sertificate** (via [certbot](http://certbot.eff.org/) for [ubuntu](https://ubuntu.com/))<br>
+1. `sudo apt install certbot python3-certbot-nginx`<br>
+2. `sudo certbot certonly --nginx`<br>
+<small><i>The **domain** must already be **bound** to the **IP-address** of the server by `CNAME`, `A` or `AAAA` record</i></small>
+
+#### **Set up firewall rules for HTTP and HTTPS requests** (for [ubuntu](https://ubuntu.com/))<br>
+1. `sudo ufw allow "NGINX Full"`<br>
+<small>1.1. <i>Make sure that the <b>port for SSH connection</b> is open</i></small><br>
+2. `sudo ufw allow 22`<br>
+3. `sudo ufw enable`
+
+### SystemD (or any alternative you like)
+You can copy an example of the systemd file from here: `/examples/systemd/arming.service`<br>
+1. `cd examples/systemd`<br>
+2. `sudo cp pechatalka.service /etc/systemd/system/pechatalka.service && sudo chmod +x /etc/systemd/system/pechatalka.service`<br>
+3. `sudo nvim /etc/systemd/system/pechatalka.service`<br>
+<small>3.1 <i>Customize the file according to your requirements</i></small><br>
+4. `sudo systemctl daemon-reload`<br>
+3. `sudo systemctl enable pechatalka`<br>
