-upgraded VM to 4 cores and 8GB RAM
+I usually run the mastodon instance on a <abbr title="virtual machine">VM</abbr>
+with two cores and 4GB of RAM. That is plenty of power for the simple tasks a
+single-user instance has to do.
 
-(also had to increase /tmp folder for pip installation of libretranslate:
+## Preface / preparations
 
+But for the installation of LibreTranslate I enhanced (after powering off the VM)
+the cores to 4 and the RAM to 8GB.
+
+While installing the needed python packages I ran out of space on the <kbd>/tmp</kbd>
+filesystem (which was just a <kbd>tmpfs</kbd> filesystem). We could increase the
+RAM to 10GB or 12GB but for me it worked by only using 8GB of RAM for this VM.
+
+### Modify <kbd>/etc/fstab</kbd> and increase <kbd>/tmp</kbd>
+
+To increase <kbd>/tmp</kbd> we log into the VM and modify the file <kbd>/etc/fstab</kbd>.
+
+```fstab
 tmpfs /tmp tmpfs size=6G,nr_inodes=10k 0 0)
+```
 
-sudo useradd --create-home --home-dir /var/lib/libretranslate libretranslate
+### Install some needed packages
 
-paru -S python-libretranslate-git cmake
+I had much prepared/installed already, but `cmake` was still missing.
 
-sudo su - libretranslate
+```console
+$ paru -S cmake
+```
 
-python -m venv venv
+## The installation of LibreTranslate
 
-source venv/bin/activate
+### Create a dedicated user for the service
 
-pip3 install --prefer-binary libretranslate
+```console
+$ sudo useradd --create-home --home-dir /var/lib/libretranslate libretranslate
+```
 
-argospm update
+Change to the new user:
 
-for lang in $(argospm search | grep -E "^translate-.._en.*"| awk '{ print $2 }' | xargs); do echo argospm install translate-${lang}\_en; done
+```console
+$ sudo su - libretranslate
+$ python -m venv venv
+$ source venv/bin/activate
+$ pip install --prefer-binary libretranslate
+$ argospm update
+```
 
-(remove echo from command to finally execute; the command shows a list of install commands)
+### Install every language possible
 
-now edit mastodon conf to use libretranslate
+```console
+$ for lang in $(argospm search | cut -d: -f1 ); do echo argospm install $lang;done
+```
 
-cd /var/lib/mastodon
+Remove `echo` from that command to actually install them (the command above prints the commands
+needed to install the languages; you can only install one at a time).
 
-add to .env.production
+#### If you only want to translate to English, use this instead
 
+```console
+$ for lang in $(argospm search | grep -E "^translate-.._en.*"| awk '{ print $2 }' | xargs); do echo argospm install translate-${lang}_en; done
+```
+
+Also remove `echo` to actually install these translation packages.
+
+### Let mastodon know of the LibreTranslate installation
+
+```console
+$ cd /var/lib/mastodon
+```
+
+Add to .env.production:
+
+```env
 ALLOWED_PRIVATE_ADDRESSES=127.0.0.1
 LIBRE_TRANSLATE_ENDPOINT=http://127.0.0.1:5000
+```
+
+### Create a systemd unit file to automatically start LibreTranslate
+
+File: <kbd>/etc/systemd/system/libretranslate.service</kbd>
+
+```systemd
+[Unit]
+Description=LibreTranslate
+After=network.target
+
+[Service]
+User=libretranslate
+Group=libretranslate
+WorkingDirectory=/var/lib/libretranslate/
+ExecStart=/var/lib/libretranslate/venv/bin/python /var/lib/libretranslate/venv/bin/libretranslate --host 0.0.0.0 --port 5000 --suggestions --req-limit 20 --update-models
+Restart=always
+#CPUQuota=50%
+
+[Install]
+WantedBy=multi-user.target
+```
+
+### Start LibreTranslate
+
+First, tell systemd of the new unit file:
+
+```console
+$ sudo systemctl daemon-reload
+```
+
+Enable and start the service:
+
+```console
+$ sudo systemctl enable --now libretranslate.service
+```
+
+## Restart Mastodon to let it know of the translation service
+
+```console
+$ sudo systemctl restart mastodon-web.service
+```
+
+## Remove the extra space from <kbd>/tmp</kbd>
+
+Comment or remove the line in <kbd>/etc/fstab</kbd>
+
+```fstab
+#tmpfs /tmp tmpfs size=6G,nr_inodes=10k 0 0)
+```
+
+## Reduce the VMs specs back to normal
+
+I set the VM back to two cores and 4GB of RAM. Poweroff the VM
+with `sudo poweroff` or `sudo systemctl poweroff` and change the values
+back to normal. Start the VM again and all services should come online.
