+## Building
+
+Build and dependencies are managed with `gradle`. To build, use:
+```sh
+./gradlew build
+```
+Dependencies are verified against a list of trusted checksums. To update this list, use:
+```sh
+$ rm -rf ~/.konan
+$ ./gradlew --write-verification-metadata sha256 clean build
+```
+Please note that this has to be done on linux, macos x64 and macos arm64 hosts (or you could download konan packages for all build machines and compute checksums manually).
