mkdir ~/OrangeFox_sync
cd ~/OrangeFox_sync
git clone https://gitlab.com/OrangeFox/sync.git # (or, using ssh, "git clone git@gitlab.com:OrangeFox/sync.git")

2. Do the syncing (this can take up to 1 hour, and can use up to 40GB of disk space) - below is an example, for 11.0 (amend as required for other branches)

cd ~/OrangeFox_sync/sync/
./orangefox_sync.sh --branch 11.0 --path ~/fox_11.0

Notes:

You MUST supply an ABSOLUTE path name for the "--path" switch
If the sync process gets stuck, you might need to terminate it with Ctrl-C and then run the script again
If you want to use ssh for cloning the OrangeFox sources and vendor tree, export "USE_SSH=1" before starting, or supply "--ssh 1" on the command line
After the initial sync process, you must then clone your device trees, before you can build for your device

These manifest branches are supported by the orangefox_sync.sh script:

12.1
11.0
10.0
9.0
8.1
7.1
6.0

To update the manifest, and the recovery sources, and the vendor trees (given the example of the 11.0 branch above), follow these steps:

cd ~/fox_11.0/
repo sync # (ignore all errors and suggestions relating to "android_bootable_recovery")
cd ~/fox_11.0/bootable/recovery/
git pull --recurse-submodules
git submodule foreach --recursive git pull origin master
cd ~/fox_11.0/vendor/recovery/
git pull

To update only the recovery sources (given the example of the 11.0 branch above), follow these steps:

cd ~/fox_11.0/bootable/recovery/
git pull --recurse-submodules
git submodule foreach --recursive git pull origin master

To update only the vendor tree (given the example of the 11.0 branch above) follow these steps:

cd ~/fox_11.0/vendor/recovery/
git pull

To update only the manifest (given the example of the 11.0 branch above), follow these steps:

cd ~/fox_11.0/
repo sync # (ignore all errors and suggestions relating to "android_bootable_recovery")
