There are several options for installation. One method is to use [nvm](https://github.com/creationix/nvm) to easily switch between different versions, or download directly from [Node.js](https://nodejs.org/). ```bash npm install -g bitcore ``` Spin up a full node and join the network: ```bash npm install -g bitcore bitcored ``` You can then view the Insight block explorer at the default location: `http://localhost:3001/insight`, and your configuration file will be found in your home directory at `~/.bitcore`. Create a transaction: ```js var bitcore = require('bitcore'); var transaction = new bitcore.Transaction(); var transaction.from(unspent).to(address, amount); transaction.sign(privateKey); ``` ## Applications - [Node](https://github.com/bitpay/bitcore-node) - A full node with extended capabilities using Bitcoin Core - [Insight API](https://github.com/bitpay/insight-api) - A blockchain explorer HTTP API - [Insight UI](https://github.com/bitpay/insight) - A blockchain explorer web user interface - [Wallet Service](https://github.com/bitpay/bitcore-wallet-service) - A multisig HD service for wallets - [Wallet Client](https://github.com/bitpay/bitcore-wallet-client) - A client for the wallet service - [CLI Wallet](https://github.com/bitpay/bitcore-wallet) - A command-line based wallet client - [Angular Wallet Client](https://github.com/bitpay/angular-bitcore-wallet-client) - An Angular based wallet client - [Copay](https://github.com/bitpay/copay) - An easy-to-use, multiplatform, multisignature, secure bitcoin wallet ## Libraries - [Lib](https://github.com/bitpay/bitcore-lib) - All of the core Bitcoin primatives including transactions, private key management and others - [Payment Protocol](https://github.com/bitpay/bitcore-payment-protocol) - A protocol for communication between a merchant and customer - [P2P](https://github.com/bitpay/bitcore-p2p) - The peer-to-peer networking protocol - [Mnemonic](https://github.com/bitpay/bitcore-mnemonic) - Implements mnemonic code for generating deterministic keys - [Channel](https://github.com/bitpay/bitcore-channel) - Micropayment channels for rapidly adjusting bitcoin transactions - [Message](https://github.com/bitpay/bitcore-message) - Bitcoin message verification and signing - [ECIES](https://github.com/bitpay/bitcore-ecies) - Uses ECIES symmetric key negotiation from public keys to encrypt arbitrarily long data streams. ## Documentation The complete docs are hosted here: [bitcore documentation](http://bitcore.io/guide/).
