now's the time to check if you have enough memory, 4GB phys and 2G+ swap, better to have 4 to match your phys
sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile

Install komodo
git clone https://github.com/komodoplatform/komodo.git
cd komodo
git checkout dev
./zcutil/fetch-params.sh
./zcutil/build.sh -j$(nproc)
the above command -j$(nproc) is equivalent to -jnproc fyi.
if your system doesn't have enough memory it will fail to compile, load some more swap
make a config file for komodo

bitcoin is not necessary (totally optional) for testnet but install it anyway for practise syncing requires 200GB of space, save your $$ if your testnet server is not readily equipped
