-
-If you want to build for `$GOARCH=amd64` and either **Windows, Linux** or **MacOS** just Go get this library and everything will work right away. 
-
-(You may also use Go modules (available since Go 1.11) to get the version of a specific branch or tag if you want to try out or use experimental features. However, beware that these versions are not necessarily guaranteed to be stable or thoroughly tested.)

+## Install [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/) and [libdeflate](https://github.com/ebiggers/libdeflate)
 
+This SDK uses [libdeflate](https://github.com/ebiggers/libdeflate) under the hood. For the SDK to work, you need to install `libdeflate` on your system which is super easy! 
+Additionally we require [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/) which facilitates linking `libdeflate` with this (cgo) SDK. 
+How exactly you install these two packages depends on your operating system.
 
-First of all, it is not encouraged to build for non-64-bit archs, as this library works best for 64-bit systems. 
-
-A list of possible GOOS,GOARCH combinations can be viewed [here](https://golang.org/doc/install/source#environment). 
-
-**Instructions:**
-
-1. You will need to compile and build the C [libdeflate](https://github.com/ebiggers/libdeflate) library for your target system by cloning the [repository](https://github.com/ebiggers/libdeflate) and executing the Makefile (specifying the build). *You should always use GCC for compilation as this produces the fastest libraries.* 
-
-2. Step 1 will yield compiled library files. You are going to want to use the static library (usually ending with .a \[in case of windows, rename .lib to .a\]), give it an adequate name (like `libdeflate_GOOS_GOARCH.a`) and copy it to the native/libs folder of this library.
-
-3. Go to the native/cgo.go file, which should roughly look like this: 
-```go
-package native
-
-/*
-#cgo CFLAGS: -I${SRCDIR}/libs/
-#cgo windows,amd64 LDFLAGS: ${SRCDIR}/libs/libdeflate_windows_amd64.a 
-#cgo linux,amd64 LDFLAGS: ${SRCDIR}/libs/libdeflate_linux_amd64.a
-#cgo darwin,amd64 LDFLAGS: ${SRCDIR}/libs/libdeflate_darwin_amd64.a
-*/
-import "C"
-```
-Now you want to add your build of libdeflate to the cgo directives, more specifically, to the linker flags, like this (omit the '+'): 
-```diff
-package native
-
-/*
-#cgo CFLAGS: -I${SRCDIR}/libs/
-+#cgo GOOS,GOARCH LDFLAGS: ${SRCDIR}/libs/libdeflate_GOOS_GOARCH.a
-#cgo windows,amd64 LDFLAGS: ${SRCDIR}/libs/libdeflate_windows_amd64.a
-#cgo linux,amd64 LDFLAGS: ${SRCDIR}/libs/libdeflate_linux_amd64.a
-#cgo darwin,amd64 LDFLAGS: ${SRCDIR}/libs/libdeflate_darwin_amd64.a
-*/
-import "C"
+#### MacOS (HomeBrew):
+```sh
+brew install libdeflate
+brew install pkg-config
 ```
 
-That's it! It should work now!
+#### Linux:
+Use the package manager available on your distro to install the required packages. 
 
-</details>
+#### Windows (MinGW/WSL2):
+Here, you can either use [WSL2](https://learn.microsoft.com/en-us/windows/wsl/install)
+or [MinGW](https://www.mingw-w64.org/) and from there install the required packages.
