+How can these be achieved?
+
+```
+LLGo := Go + C + Python
+```
+
+LLGo is compatible with C and Python through the language's **Application Binary Interface (ABI)**, while LLGo is compatible with Go through its **syntax (source code)**.

+
+## How support C/C++ and Python
+
+LLGo use `go:linkname` to link an extern symbol througth its ABI:
+
+```go
+import _ "unsafe" // for go:linkname
+
+//go:linkname Sqrt C.sqrt
+func Sqrt(x float64) float64
+```
+
+You can directly integrate it into [your own code](_demo/linkname/linkname.go):
+
+```go
+package main
+
+import _ "unsafe" // for go:linkname
+
+//go:linkname Sqrt C.sqrt
+func Sqrt(x float64) float64
+
+func main() {
+	println("sqrt(2) =", Sqrt(2))
+}
+```
+
+Or put it into a package (see [c/math](c/math/math.go)):

+```go
+package main
+
+import "github.com/goplus/llgo/c/math"
+
+func main() {

+### on macOS (Homebrew)
+
+```sh
+brew install libuv
+```
+
+### on Linux (Debian/Ubuntu)
+
+```sh
+apt-get install -y libuv1-dev

+
+## Demos
+
+The `_demo` directory contains our demos (it start with `_` to prevent the `go` command from compiling it):
+
+* [async_fs](_demo/async_fs/async_fs.go): a simple async file read demo
+* [echo_server](_demo/echo_server/echo_server.go): a basic async tcp echo server
+
+### How to run demos
+
+To run the demos in directory `_demo`:
+
+```sh
+cd <demo-directory>  # eg. cd _demo/sqlitedemo
+llgo run .
