+# Publishing secp256k1-kmp artifacts
+
+## snapshots
+
+Snapshots are published to the Sonatype snapshot repository (https://oss.sonatype.org/content/repositories/snapshots/).
+To publish snapshot, you must add your sonatype credentials for the `ossrh` server to your local maven settings (typically in $HOME/.m2/settings.xml)
+
+- Download `snapshot.zip` generated by the `Publish snapshot` github action
+- unzip `snapshot.zip` in the `publishing` directory
+- add additional JNI bindings (optional, see below)
+- edit `secp256k1-kmp-snapshot-deploy.sh` and update the `VERSION` environment variable if needed
+- run `secp256k1-kmp-snapshot-deploy.sh`
+
+## releases
+
+Releases are published to the Sonatype staging repository. If all items are valid they will be published to `maven central` repository.
+You must edit `secp256k1-kmp-staging-upload.sh` and add your sonatype credentials. You must also have a valid GPG key.
+
+- Download `release.zip` generated by the `Publish release` github action (which is triggered every time you publish a github release)
+- unzip `release.zip` in the `publishing` directory
+- add additional JNI bindings (optional, see below)
+- edit `secp256k1-kmp-staging-upload.sh` and update the `VERSION` environment variable if needed
+- sign all artifacts with a valid gpg key: `find release -type f -print -exec gpg -ab {} \;`
+- run `secp256k1-kmp-staging-upload.sh`
+- log into sonatype, close and publish your staging repository. Artifacts will be available on Maven Central within a few hours.
+
+## Adding custom JNI bindings
+
+Github CI currently generates JNI bindings for Windows x64, Linux x64 and iOS x64. But it is possible to add custom bindings to JNI packages before 
+they are published to maven central. This is how we add linux arm64 bindings:
+- compile JNI bindings for Linux Arm64 (on a Linux Arm64 machine, cross-compilation is not supported)
+  - git clone --recursive https://github.com/ACINQ/secp256k1-kmp.git
+  - cd secp256k1-kmp 
+  - TARGET=linux ./native/build.sh 
+  - mkdir -p jni/jvm/build/linux 
+  - TARGET=linux ./jni/jvm/build.sh 
+  - JNI library is: jni/jvm/build/linux/libsecp256k1-jni.so
+- copy libsecp256k1-jni.so to fr/acinq/secp256k1/jni/native/linux-aarch64/libsecp256k1-jni.so
+- run `secp256k1-kmp-add-linuxarm64.sh` and specify either `release` or `snapshot` and the `VERSION` environment variable, for example:
+  - VERSION=0.6.4-SNAPSHOT ./secp256k1-kmp-add-linuxarm64.sh snapshot
+  - VERSION=0.6.3 ./secp256k1-kmp-add-linuxarm64.sh release
