+## Sample Buck project
+
+Most interesting for you here is not the source code, but configs in [`.mainframer`](.mainframer) folder.
+
+This is a very common setup for basically any Buck project (including multimodule), but of course you might need to tune some ignore configs for your project.
+
+### How to build
+
+```bash
+$ bash mainframer.sh buck build sample
+```
+
+Or any other Buck task you want, btw it integrates with IntelliJ pretty easily! TODO add link to docs.
+
+### Requirements
+
+* Buck installed on remote machine.
+* JDK 8+ installed on remote machine.
