+# Overview
+We aim for the main branch of the repository to always be in a releasable state.
+
+Two types of artifacts can be published:
+1. Snapshot — An unstable release of the library for testing
+1. Release — A stable release of the library
+
+Control of these modes of release is managed with a Gradle property `IS_SNAPSHOT`.
+
+For both snapshot and release publishing, there are two ways to initiate deployment:
+1. Automatically
+2. Manually
+
+This document will focus initially on the automated process, with a section at the end on manual process.  (The automated process more or less implements the manual process via GitHub Actions.)
+
+# Automated Publishing
+## Snapshots
+All merges to the main branch trigger an automated [snapshot deployment](https://github.com/zcash/kotlin-bip39/actions/workflows/deploy-snapshot.yml).
+
+Note that snapshots do not have a stable API, so clients should not depend on a snapshot.  The primary reason this is documented is for testing, e.g. before deploying a new production version of the library we may test against the snapshot first.
+
+Snapshots can be consumed by:
+
+1. Adding the snapshot repository
+settings.gradle.kts:
+```
+dependencyResolutionManagement {
+    repositories {
+        maven("https://oss.sonatype.org/content/repositories/snapshots") {
+            // Optional; ensures only explicitly declared dependencies come from this repository
+            content {
+                includeGroup("cash.z.ecc.android")
+            }
+        }
+    }
+}
+```
+
+2. Changing the dependency version to end with `-SNAPSHOT`
+
+3. Rebuilding
+`./gradlew assemble --refresh-dependencies`
+
+Because Gradle caches dependencies and because multiple snapshots can be deployed under the same version number, using `--refresh-dependencies` is important to ensure the latest snapshot is pulled.
+
+## Releases
+Production releases can be consumed using the instructions in the [README.MD](../README.md).  Note that production releases can include alpha or beta designations.
+
+Automated production releases still require a manual trigger.  To do a production release:
+1. Update the [CHANGELOG.MD](../CHANGELOG.md) for any new changes since the last production release.
+1. Run the [release deployment](https://github.com/zcash/kotlin-bip39/actions/workflows/deploy-release.yml).
+1. Confirm deployment succeeded by modifying the [Secant Android Wallet](https://github.com/zcash/secant-android-wallet) to consume the new version.
+1. Create a new Git tag for the new release in this repository.
+1. Create a new pull request bumping the version to the next version (this ensures that the next merge to the main branch creates a snapshot under the next version number).
+
+# Manual Publishing
+See [ci.md](ci.md), which describes the continuous integration workflow for deployment and describes the secrets that would need to be configured in a repository fork.
+
+## One time only
+* Set up environment to compile the library
+* Copy the GPG key to a directory with proper permissions (chmod 600). Note: If you'd like to quickly publish locally without subsequently publishing to Maven Central, configure a Gradle property `RELEASE_SIGNING_ENABLED=false`
+* Create file `~/.gradle/gradle.properties` per the [instructions in this guide](https://proandroiddev.com/publishing-a-maven-artifact-3-3-step-by-step-instructions-to-mavencentral-publishing-bd661081645d)
+  * add your sonotype credentials with these properties
+      * `mavenCentralUsername`
+      * `mavenCentralPassword`
+  * point it to the GPG key with these properties
+     * `signing.keyId`
+     * `signing.password`
+     * `signing.secretKeyRingFile`
+
+## Every time
+1. Update the [build number](https://github.com/zcash/kotlin-bip39/blob/main/gradle.properties) and the [CHANGELOG](https://github.com/zcash/kotlin-bip39/blob/main/CHANGELOG.md).  For release builds, suffix the Gradle invocations below with `-PIS_SNAPSHOT=false`.
+3. Build locally
+    * This will install the files in your local maven repo at `~/.m2/repository/cash/z/ecc/android/`
+```zsh
+./gradlew publishToMavenLocal
+```
+4. Publish via the following command:
+```zsh
+# This uploads the file to sonotype’s staging area
+./gradlew publish --no-daemon --no-parallel
+```
+5. Deploy to maven central:
+```zsh
+# This closes the staging repository and releases it to the world
+./gradlew closeAndReleaseRepository
+```
+
+Note:
+Our existing artifacts can be found here and here:
+https://search.maven.org/artifact/cash.z.ecc.android/kotlin-bip39

+# Continuous Integration
+Continuous integration is set up with GitHub Actions.  The workflows are defined in this repo under [/.github/workflows](../.github/workflows).
+
+Workflows exist for:
+ * Pull request - On pull request, static analysis and testing is performed.
+ * Snapshot deployment - On merge to the main branch, a snapshot release is deployed to Maven Central.  Concurrency limits are in place, to ensure that only one snapshot deployment can happen at a time.
+ * Release deployment - Manually invoked workflow to deploy to Maven Central.  Concurrency limits are in place, to ensure that only one release deployment can happen at a time.
+ * Unwedge — If Snapshot deployment fails, it will often be due to multiple unclosed repositories.  This workflow can take a given open repository name and attempt to close it.
+ 
+## Setup
+When forking this repository, some secrets need to be defined to set up new continuous integration builds.
+
+The secrets passed to GitHub Actions then map to Gradle properties set up within our build scripts.  Necessary secrets are documented at the top of each GitHub workflow yml file, as well as reiterated here.
+
+### Pull request
+No configuration is required.
+
+### Snapshot deployment
+* `MAVEN_CENTRAL_USERNAME` — Username for Maven Central, which maps to the Gradle property `mavenCentralUsername`.
+* `MAVEN_CENTRAL_PASSWORD` — Password for Maven Central, which maps to the Gradle property `mavenCentralPassword`.
+
+GPG keys are not needed for snapshot deployment.
+
+Note: For documentation on the Gradle properties for Maven deployment, see [Gradle Maven Publish Plugin](https://github.com/vanniktech/gradle-maven-publish-plugin).
+
+Note: Snapshot builds are configured with a Gradle property `IS_SNAPSHOT`.  The workflow automatically sets this property to true for snapshot deployments.  This will suffix the version with `-snapshot` and will upload to the snapshot repository.
+
+### Release deployment
+* `MAVEN_CENTRAL_USERNAME` — Username for Maven Central, which maps to the Gradle property `mavenCentralUsername`.
+* `MAVEN_CENTRAL_PASSWORD` — Password for Maven Central, which maps to the Gradle property `mavenCentralPassword`.
+* `MAVEN_SIGNING_KEYRING_FILE_BASE64` — GPG keyring file, base64 encoded.  Maps to Gradle property `signing.secretKeyRingFile`.
+* `MAVEN_SIGNING_KEY_ID` — Name of key inside GPG keyring file.  Maps to Gradle property `signing.keyId`.
+* `MAVEN_SIGNING_PASSWORD` — Password for key inside GPG keyring file.  Maps to Gradle property `signing.password`.
+
+Note: For documentation on the Gradle properties for Maven deployment, see [Gradle Maven Publish Plugin](https://github.com/vanniktech/gradle-maven-publish-plugin).
+
+Note: Snapshot builds are configured with a Gradle property `IS_SNAPSHOT`.  The workflow automatically sets this property to false for release deployments.
+
+### Unwedge
+* `MAVEN_CENTRAL_USERNAME` — Username for Maven Central, which maps to the Gradle property `mavenCentralUsername`.
+* `MAVEN_CENTRAL_PASSWORD` — Password for Maven Central, which maps to the Gradle property `mavenCentralPassword`.
