It provides a local dashboard which you can access through your browser, to discover what others are sharing without knowing other's IP addresses.\n\nRun Gocho, browse to [localhost:1337](http://localhost:1337) and see what others are sharing!\n\n\n![alt Gocho dashboard](docs/gocho-dashboard.gif)\n\n> **Building The Project:**\n>\n> If you want to help and contribute don't forget to check the [Building document](docs/building.md) in order to have your environment ready.\n\n## Install\n[Download the latest release](https://github.com/donkeysharp/gocho/releases) for your operating system. Currently the following operating systems are being supported:\n\n* GNU/Linux 32 bits\n* GNU/Linux 64 bits\n* OSX\n* Windows 32 bits\n* Windows 64 bits\n\nDownload, unzip the file and add it to your path or a directory that is already in your system's path.\n\n**Example unix-like**\n\n $ unzip gocho_0.1.0_darwin.zip\n $ mv gocho /usr/bin\n $ gocho --help\n\n## Instructions\nGocho needs to be executed using the command line in order to initiate the sharing.\n\nThere are two ways to start sharing:\n1. Specify the settings on a config file\n2. Specify the settings using command line flags.\n\n### Specify a settings file\nGocho reads a settings file that is located at `$USER_HOME/.gocho.conf`. The format of the file is as follows:\n\n```\nNodeId: my-computer\nWebPort: \"5555\"\nLocalPort: \"1337\"\nShareDirectory: /home/user/some/directory\n```\n\nIf you want Gocho to create this file for you, it's possible to run the configuration wizard by running:\n\n $ gocho configure\n\nWhich will ask for the different settings and create a `.gocho.conf` file.\n\nOnce settings file is created, run the next to start sharing:\n\n $ gocho start\n\n![alt Gocho wizard](docs/gocho-configure.gif)\n\n### Use command line flags\nIf you don't want to specify a configuration file, or want to share a directory which is not specified on the `.gocho.conf` file, run:\n\n $ gocho start --dir /some/directory --id my-computer-tmp\n\nThis is the list of available flags\n\nFlag | Description\n--- | ---\n--id {value} | Node ID that will be shared to other peers (**Required**)\n--dir {value} | Directory to share (**Required**)\n--share-port {value} | Port that will be exposed for file sharing (default: \"5555\")\n--local-port {value} | Port for local dashboard (default: \"1337\")\n\n\n![alt Gocho flags](docs/gocho-start.gif)\n\n## License\nLicensed under the MIT License.

The `generate` command in the Makefile creates an `assets/assets_gen.go` file with the embedded UI code.\n\n $ make generate\n\nSo far the previous steps need to be run only the first time unless you are modifying UI, in that case check the `UI Development` section.\n\nTo build `gocho` binary and test it while you do changes run:\n\n $ make build-dev\n\nWhich will create the `gocho` binary at `$GOPATH/bin/gocho` as that command runs `go install github.com/donkeysharp/gocho/cmd/gocho`\n\n## UI Development\nGocho UI uses React and was intialized using [Create React App](https://github.com/facebook/create-react-app).\n\nAll React code for the dashboard is located in the `ui` directory. This directory has the package.json and the yarn.lock file, in order to develop and test the UI you need to run the next\n\n $ cd ui\n # Install UI dependencies\n $ yarn install\n # Start development server\n $ yarn start\n\nThat will bring up a development server at http://localhost:3000 with the UI so it can be developed. The development server for UI is configured to use a proxy to `http://localhost:1337` (see `package.json`) so it's important to have a backend running, check `Service Development` section.\n" }, {
