To make automated tests work in Idea:

1. Download https://github.com/ACINQ/eclair/commit/98bb7be70a4fc96242409b90fbf1ec9c5ff470e6 (latest release).
2. Compile Eclair with $ '/home/anton/apache-maven-3.6.3/bin/mvn' install -DskipTests (things need to be done this way to get eclair-tests jar file which is not included in prebuilt download package).
3. Download https://github.com/btcontract/plugin-hosted-channels.
4. Create a folder <HC>/lib/
5. Go to <Eclair> folder with compiled stuff.
6. Copy <Eclair>/eclair-core/target/eclair-core_2.13-0.5.1-tests.jar to <HC>/lib/.
7. Unpack <Eclair>/eclair-node/target/eclair-node-0.5.1-98bb7be-bin.zip, copy all <UNPACKED>/lib/*.jar to <HC>/lib/.
8. Open HC in Idea, go to File -> Project structure -> Modules -> Dependencies.
9. Tap +, locate <HC>/lib/, add all jar files, apply.
10. Copy <HC>/src/main/resouces/hc.conf into <HC>/plugin-resources/hosted-channels/hc.conf.
11. Get up local postgre cluster, make databases named hc, hcalice, hcbob (last two are needed for testing, first one will be storing production data, I recommend using pgadmin4 web interface for local stuff).
12. To make a plugin jar: go to <HC> in console, then $ sbt, then $sbt> assembly, jar file can be found at <HC>/target/scala-2.13/.

To make production work:

1. Download https://github.com/ACINQ/eclair/commit/98bb7be70a4fc96242409b90fbf1ec9c5ff470e6 (latest release).
2. Compile Eclair with $ '/home/anton/apache-maven-3.6.3/bin/mvn' install -DskipTests.
3. Create an .eclair folder in home, extract <Eclair>/eclair-node/target/eclair-node-0.5.1-98bb7be-bin.zip contents into it, copy <HC>/target/scala-2.13/hc-assembly-0.1.jar into it (to have all files in one place).
4. Copy <HC>/src/main/resouces/hc.conf into .eclair/plugin-resources/hosted-channels/hc.conf.
5. Get up local postgre cluster, make database named hc.
6. Run $ './bin/eclair-node.sh' './hc-assembly-0.1.jar', an .eclair/eclair.log file should contain a line INFO fr.acinq.eclair.Boot - loaded plugin HC.

• On first run, set attemptCreateTables = true in .eclair/plugin-resources/hosted-channels/hc.conf, for subsequent runs update it to attemptCreateTables = false. If not updated Eclair will be failing on startup, but HC data won't be lost.
• Enable api block in Eclair's reference.conf and then configure HC API in hc.conf. HC API is not documented yet but tl/dr HC plugin supports its own set of API endpoints to manage stuff, they can be seen at https://github.com/btcontract/plugin-hosted-channels/blob/master/src/main/scala/fr/acinq/hc/app/api/HCService.scala
