docs: simplify README and link to the documentation site

Point the README at the published docs site
(https://skyapm.github.io/SkyAPM-dotnet/) for full guides, and trim the
duplicated Getting Started / How to use / Configuration / Features sections
that now live there. Also fixes the README's stale `docs/...` relative links
(the docs were moved under `content/` for the Hugo site).

 **SkyAPM-dotnet** is a community, open-source C#/.NET auto-instrumentation agent for the .NET ecosystem. It provides distributed tracing, application topology, and metrics for ASP.NET Core and .NET applications, and reports the collected telemetry to an [Apache SkyWalking](https://skywalking.apache.org/) backend over the `sw8` / `v8` protocol. It is an independent project and is not affiliated with or endorsed by the Apache Software Foundation.

-# Getting Started
-
-## Deploy SkyWalking Backend And UI
-
-#### Requirements
-Start with v1.0.0, SkyAPM .NET Core Agent only supports SkyWalking 8.0 or higher. The SkyWalking doc is [here](https://skywalking.apache.org/docs/).
-
-## Install SkyWalking .NET Core Agent
-
-You can run the following command to install the SkyWalking .NET Core Agent in your project.
-
-```
-dotnet add package SkyAPM.Agent.AspNetCore
-```
-
-## How to use
-Set the `ASPNETCORE_HOSTINGSTARTUPASSEMBLIES` environment variable to support the activation of the SkyAPM .NET Core Agent.
-
-- Add the assembly name of `SkyAPM.Agent.AspNetCore` to the `ASPNETCORE_HOSTINGSTARTUPASSEMBLIES` environment variable.
-
-### Examples
-- On windows
-
-```
-dotnet new mvc -n sampleapp
-cd sampleapp
-dotnet add package SkyAPM.Agent.AspNetCore
-set ASPNETCORE_HOSTINGSTARTUPASSEMBLIES=SkyAPM.Agent.AspNetCore
-set SKYWALKING__SERVICENAME=sample_app
-dotnet run
-```
+## Quick start
 
-- On macOS/Linux
+Supported runtimes: **net8.0** and **net10.0**.
 
-```
-dotnet new mvc -n sampleapp
-cd sampleapp
-dotnet add package SkyAPM.Agent.AspNetCore
-export ASPNETCORE_HOSTINGSTARTUPASSEMBLIES=SkyAPM.Agent.AspNetCore
-export SKYWALKING__SERVICENAME=sample_app
+```bash
+dotnet add package SkyApm.Agent.AspNetCore
+export ASPNETCORE_HOSTINGSTARTUPASSEMBLIES=SkyApm.Agent.AspNetCore
+export SKYWALKING__SERVICENAME=my_service
 dotnet run
 ```
 
-## Configuration
-
-Install `SkyAPM.DotNet.CLI`
-
-```
-dotnet tool install -g SkyAPM.DotNet.CLI
-```
-
-For 2.2.x or older, use `dotnet skyapm config [your_service_name] [your_servers]` to generate config file.
-
-```
-dotnet skyapm config sample_app 192.168.0.1:11800
-```
-
-For 2.3.x or newer, use `dotnet skyapm config ${your_service_name} [--reporter=grpc|kafka] [--grpcservers=...] [--kafkaservers=...]` to generate config file.
+See [**Getting Started**](https://skyapm.github.io/SkyAPM-dotnet/docs/guides/getting-started/) for the full walkthrough, and the [**Configuration reference**](https://skyapm.github.io/SkyAPM-dotnet/docs/guides/skyapm_config/) for every option.

-If you have issues about SkyWalking protocol, its official backend, ask questions at their Apache official channels. All following channels are not suitable for .net agent, but good if you are facing backend/UI issues.
+For questions about the **SkyWalking protocol or its backend/UI**, use the official Apache SkyWalking channels (these are not suitable for the .NET agent):
 * Submit an official Apache SkyWalking [issue](https://github.com/apache/skywalking/issues).
 * Mail list: **dev@skywalking.apache.org**. Mail to `dev-subscribe@skywalking.apache.org`, follow the reply to subscribe the mail list.
