# I used this shell.nix to build LineageOS 13.0 for my maguro (Samsung Galaxy Nexus GSM) phone
# The build instructions for normal Linuxes are here: https://wiki.lineageos.org/devices/maguro/build
# For NixOS, follow those instructions but skip anything related to installing packages
# Detailed instructions:
#   cd into an empty directory of your choice
#   copy this file there
#   in nix-shell:
#    $ repo init -u https://github.com/LineageOS/android.git -b cm-13.0
#    $ repo sync
#    $ source build/envsetup.sh
