 # `@metamask/java-tron-up`
 
-java-tron runtime installer for MetaMask E2E tests
+`java-tron-up` installs a pinned native java-tron runtime for local development
+and CI. It follows the same runtime-only shape as `@metamask/foundryup`: this
+package installs external runtime artifacts into the MetaMask cache and exposes
+binaries in `node_modules/.bin`; the consuming test harness owns process
+startup, private-network config, readiness checks, and seeding.
 
-## Installation
+This package does not use Docker and does not start or seed a TRON node.
 
-`yarn add @metamask/java-tron-up`
+## Usage
 
-or
+Install the package in the consuming repo:
 
-`npm install @metamask/java-tron-up`
+```bash
+yarn add @metamask/java-tron-up
+npm install @metamask/java-tron-up
+```
 
-## Contributing
+For Yarn v4 projects, it is usually simplest to add package scripts in the
+consuming repo:
 
-This package is part of a monorepo. Instructions for contributing can be found in the [monorepo README](https://github.com/MetaMask/core#readme).
+```json
+{
+  "scripts": {
+    "java-tron-up": "node_modules/.bin/java-tron-up",
+    "java-tron": "node_modules/.bin/java-tron"
+  }
+}
+```
+
+Install java-tron and its managed Java runtime:
+
+```bash
+yarn java-tron-up install
+```
+
+Run the installed node wrapper:
+
+```bash
+node_modules/.bin/java-tron -c /absolute/path/to/fullnode.conf --witness
+```
+
+For MetaMask Extension E2E tests, the Tron seeder should spawn
+`node_modules/.bin/java-tron`, pass its generated private-network config, poll
+java-tron's HTTP APIs directly, and perform all account/token/staking seeding
+itself.
+
+## Installed Artifacts
+
+`java-tron-up` installs:
+
+- a platform-specific `FullNode.jar`
+- a managed Java runtime matching java-tron's architecture requirements
+- a `node_modules/.bin/java-tron` wrapper that runs:
+
+```bash
+java -jar FullNode.jar "$@"
+```
+
+## CLI
+
+```bash
+java-tron-up [install] [options]
+java-tron-up cache clean [options]
+```
+
+Options:
+
+- `--bin-directory <path>`: directory for generated wrappers. Defaults to
+  `node_modules/.bin`.
+- `--cache-directory <path>`: artifact cache directory. Defaults to
+  `.metamask/cache`.
+- `--full-node-url <url>` and `--full-node-checksum <hash>`: override the
+  FullNode jar for the current platform.
+- `--java-runtime-url <url>` and `--java-runtime-checksum <hash>`: override the
+  Java runtime archive for the current platform.
+- `--platform <platform>`: override platform selection, for example
+  `linux-x64`.
+
+## Default Release
+
+The package currently pins java-tron `GreatVoyage-v4.8.1` for `darwin-arm64`,
+`darwin-x64`, `linux-arm64`, and `linux-x64`.
+
+java-tron `4.8.1` requires JDK 8 for x86_64 and JDK 17 for arm64, so this
+package installs Azul Zulu Java 8 on x64 platforms and Azul Zulu Java 17 on
+arm64 platforms.
+
+## Cache
+
+The cache defaults to `.metamask/cache` in the current repo. If `.yarnrc.yml`
+contains `enableGlobalCache: true`, the cache moves to `~/.cache/metamask`,
+matching the `@metamask/foundryup` behavior.
+
+Clean only this package's cache namespace:
+
+```bash
+yarn java-tron-up cache clean
+```
+
+## Package Config
+
+The consuming repo can override the pinned artifact URLs and checksums in its
+root `package.json`:
+
+```json
+{
+  "javaTronUp": {
+    "fullNode": {
+      "version": "GreatVoyage-v4.8.1",
+      "platforms": {
+        "linux-x64": {
+          "url": "https://github.com/tronprotocol/java-tron/releases/download/GreatVoyage-v4.8.1/FullNode.jar",
+          "checksum": "0e67b2fe75d7077750e73c4fa20725c6e9824657275d96be256ae5da681f9945"
+        }
+      }
+    }
+  }
+}
+```
+
+Supported package config keys are `javaTronUp`, `javatronup`, and
+`java-tron-up`.
