 # `@metamask/bitcoin-regtest-up`
 
-Bitcoin Core regtest runtime installer for MetaMask E2E tests
+`bitcoin-regtest-up` installs a pinned Bitcoin Core 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, regtest config, readiness checks, and seeding.
 
-## Installation
+This package does not use Docker and does not start or seed a Bitcoin node.
 
-`yarn add @metamask/bitcoin-regtest-up`
+## Usage
 
-or
+Install the package in the consuming repo:
 
-`npm install @metamask/bitcoin-regtest-up`
+```bash
+yarn add @metamask/bitcoin-regtest-up
+npm install @metamask/bitcoin-regtest-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": {
+    "bitcoin-regtest-up": "node_modules/.bin/bitcoin-regtest-up",
+    "bitcoind": "node_modules/.bin/bitcoind",
+    "bitcoin-cli": "node_modules/.bin/bitcoin-cli"
+  }
+}
+```
+
+Install bitcoind and bitcoin-cli:
+
+```bash
+yarn bitcoin-regtest-up install
+```
+
+Run the installed Bitcoin Core wrappers:
+
+```bash
+node_modules/.bin/bitcoind -regtest
+node_modules/.bin/bitcoin-cli -regtest getblockchaininfo
+```
+
+For MetaMask Extension E2E tests, the Bitcoin seeder should spawn
+`node_modules/.bin/bitcoind`, pass its generated regtest datadir and ports, use
+`node_modules/.bin/bitcoin-cli` for node setup, poll JSON-RPC directly, and
+perform all wallet/funding seeding itself.
+
+## Installed Artifacts
+
+`bitcoin-regtest-up` installs:
+
+- a platform-specific Bitcoin Core release archive
+- a `node_modules/.bin/bitcoind` wrapper
+- a `node_modules/.bin/bitcoin-cli` wrapper
+
+## CLI
+
+```bash
+bitcoin-regtest-up [install] [options]
+bitcoin-regtest-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`.
+- `--bitcoin-core-url <url>` and `--bitcoin-core-checksum <hash>`: override the
+  Bitcoin Core archive for the current platform.
+- `--platform <platform>`: override platform selection, for example
+  `linux-x64`.
+
+## Default Release
+
+The package currently pins Bitcoin Core `30.2` for `darwin-arm64`,
+`darwin-x64`, `linux-arm64`, and `linux-x64`.
+
+## 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 bitcoin-regtest-up cache clean
+```
+
+## Package Config
+
+The consuming repo can override the pinned artifact URLs and checksums in its
+root `package.json`:
+
+```json
+{
+  "bitcoinRegtestUp": {
+    "bitcoinCore": {
+      "version": "30.2",
+      "platforms": {
+        "linux-x64": {
+          "url": "https://bitcoincore.org/bin/bitcoin-core-30.2/bitcoin-30.2-x86_64-linux-gnu.tar.gz",
+          "checksum": "6aa7bb4feb699c4c6262dd23e4004191f6df7f373b5d5978b5bcdd4bb72f75d8"
+        }
+      }
+    }
+  }
+}
+```
+
+Supported package config keys are `bitcoinRegtestUp`, `bitcoinregtestup`, and
+`bitcoin-regtest-up`.
