+# Intro
+
+Hello.
+
+Some instructions how to build rpm file and then install rpm file on Bazzite.
+
+I saw video on Youtube about Asrock AMD BC-250, then I bought this motherboard.
+
+On printables I found a case and recomendations about WIFI BT stick.
+
+There is only one problem - Bazzite has read-only filesystem. 
+
+# How to build from spec file.
+
+
+Install required packages and then reboot after install to apply changes.
+
+~~~bash
+sudo rpm-ostree install rpm-build rpmdevtools
+sudo systemctl reboot
+~~~
+
+Prepare rpmbuild folder
+
+~~~bash
+cd $HOME
+rpmdev-setuptree
+~~~
+
+Copy aic8800d80.spec to rpmbuild/SPECS
+
+~~~bash
+cp aic8800d80.spec $HOME/rpmbuild/SPECS
+~~~
+
+Prepare and download required files.
+
+~~~bash
+spectool -g -R $HOME/rpmbuild/SPECS/aic8800d80.spec
+rpmbuild -bs $HOME/rpmbuild/SPECS/aic8800d80.spec
+~~~
+
+Enable user overlay
+
+~~~bash
+sudo rpm-ostree usroverlay
+~~~
+
+
+Build SRPM package
+
+~~~bash
+rpmbuild -bb $HOME/rpmbuild/SPECS/aic8800d80.spec
+~~~
+
+Install RPM package
+
+~~~bash
+sudo rpm-ostree install $HOME/rpmbuild/RPMS/x86_64/aic8800d80-454feef-1.fc43.x86_64.rpm
+sudo systemctl reboot
+~~~
+
+
+After reboot wifi module will load automatically.
