# PristonTale EU for Linux

Version 0.8.3 installs, updates, repairs, and launches PristonTale EU through a
native Linux dashboard. Game files come directly from the publisher and are not
included in this archive.

## Install

Keep the archive, detached signature, checksum, and
`launcher-update-public.pem` together. First confirm the public-key fingerprint
through an independent trusted channel; the expected DER SHA-256 fingerprint is
`3ae6e8dc483b93796b32e3ca270c367d247caf8d047eb796826c8e558a4a9e34`.
Then run:

```text
openssl pkey -pubin -in launcher-update-public.pem -outform DER | sha256sum
openssl dgst -sha256 -verify launcher-update-public.pem \
  -signature pristontale-eu-linux-installer-v0-8-3.tar.gz.sig \
  pristontale-eu-linux-installer-v0-8-3.tar.gz
sha256sum -c pristontale-eu-linux-installer-v0-8-3.tar.gz.sha256
tar -xzf pristontale-eu-linux-installer-v0-8-3.tar.gz
cd pristontale-eu-linux-installer-v0-8-3
./install.sh
```

The default installation directory is `~/Games/PristontaleEU`. To use another
disk or directory:

```text
./install.sh --install-dir "/path/to/PristontaleEU"
```

Existing installations at the previous default location are preserved during
upgrades. The installer adds **PristonTale EU** to the application menu and
installs the `pristontale-eu` command in `~/.local/bin`.

Steam Proton 7.0 is discovered in both the default Steam library and secondary
libraries registered with the Steam client. If Proton uses an unregistered
manual layout, open **Settings → Optional Overrides** and select the exact
`Proton 7.0/proton` script.

## Use

Open **PristonTale EU** from the application menu or run:

```text
pristontale-eu gui
```

The main launcher button automatically shows **Install**, **Update**, or
**Play** according to the managed game's state.
