You could install it alongside Bitcoin Core. Once it has synced you can pass user/password and it will use your bitcoind instead of remote blocks. Read the README, it's all there:

```
add-apt-repository ppa:lightningnetwork/ppa
apt update
apt install lightningd
mkdir -p ~/.lightning/plugins
echo 'disable-plugin=bcli' >> .lightning/config
cd ~/.lightning/plugins
wget https://github.com/nbd-wtf/trustedcoin/releases/download/v0.6.1/trustedcoin-v0.6.1-linux-amd64.tar.gz
tar -xvf trustedcoin-v0.6.1-linux-amd64.tar.gz
cd
lightningd
```

What are you working on this week?

Shall I install it before BTCcore finish the sync? Not really that technical so maybe need some support here ...
