## 🚀 Getting Started

Firstly, decide if you want to host an instance yourself or use a [third-party host](https://docs.btcpayserver.org/ThirdPartyHosting/). If you've chosen to self-host, there are plenty of documented [ways to deploy BTCPay Server](https://docs.btcpayserver.org/Deployment/).

After successful deployment, make sure to check our [getting started](https://docs.btcpayserver.org/RegisterAccount/) and [walkthrough](https://docs.btcpayserver.org/Walkthrough/) guides. In case you would like to use Lightning Network, see [Lightning guide](https://docs.btcpayserver.org/LightningNetwork/).

## 📗 Documentation

Please check out our [official website](https://btcpayserver.org/), [complete documentation](https://docs.btcpayserver.org/) and [FAQ](https://docs.btcpayserver.org/FAQ/) for more details.

If you have trouble using BTCPay Server, consider joining [communities listed on the official website](https://btcpayserver.org/#communityCTA) to get help from other contributors. Only create a [GitHub issue](https://github.com/btcpayserver/btcpayserver/issues/new/choose) for technical issues you can't resolve through other channels or feature requests you've validated with other members of the community.

* [Setting up development environment on Windows](https://www.youtube.com/watch?v=ZePbMPSIvHM)
* [Setting up development environment Linux (Ubuntu)](https://www.youtube.com/watch?v=j486T_Rk-yw&t)
* [Setting up development environment MacOS](https://www.youtube.com/watch?v=GWR_CcMsEV0)

### How to build

While the documentation advises using docker-compose, you may want to build BTCPay Server yourself.

First, install .NET SDK v8.0 as specified by the [Microsoft website](https://dotnet.microsoft.com/download/dotnet/8.0).

On Powershell:

```powershell
.\build.ps1
```

On linux:

```sh
./build.sh
```

### How to run

Use the `run` scripts to run BTCPay Server, this example shows how to print the available command-line arguments of BTCPay Server.

On Powershell:

```powershell
.\run.ps1 --help
```

On linux:

```sh
./run.sh --help
```

### How to debug

If you want to debug, use Jetbrain's Rider or Visual Studio 2022.

You need to run the development time docker-compose as described [in the test guide](./BTCPayServer.Tests/README.md).

You can then run the debugger by using the Launch Profile `Docker-Regtest`.

If you need to debug ledger wallet interaction, install the development time certificate with:

```bash
# Install development time certificate in the trust store
dotnet dev-certs https --trust
```

Then use the `Docker-Regtest-https` debug profile.

### Other dependencies

For more information, see the documentation:
[How to deploy a BTCPay Server instance](https://docs.btcpayserver.org/Deployment/).

### 🧪 API

BTCPay Server has two APIs:

- **Greenfield API (New)**
  - [Greenfield API documentation](https://docs.btcpayserver.org/API/Greenfield/v1/)
  - [Greenfield API examples with CURL](https://docs.btcpayserver.org/GreenFieldExample/)
- **Legacy API**

The **Greenfield API** is our brand-new API which is still in development. Once complete, it will allow you to run BTCPay Server headlessly.
The **Legacy API**, is fully compatible with [BitPay's API](https://bitpay.com/api/). It has limited features, but allows instant migration from BitPay.
