-# Embed C in Java Using GraalWasm
-
-The example below demonstrates how to compile a C function to WebAssembly and run it embedded in a Java application. 
-
-### Prerequisites
-
-To run the demo, you need the following:
-- [GraalVM JDK](https://www.graalvm.org/downloads/)
-- [Emscripten compiler frontend](https://emscripten.org/docs/tools_reference/emcc.html)
-- [Maven](https://maven.apache.org/)
-
-### Demo Part
-
-1. Put the following C program in a file named _floyd.c_:
-    ```c
-    #include <stdio.h>
-
-    void floyd() {
-        int number = 1;
-        int rows = 10;
-        for (int i = 1; i <= rows; i++) {
-            for (int j = 1; j <= i; j++) {
-                printf("%d ", number);
-                ++number;
-            }
-            printf(".\n");
-        }
-    }
-
-    int main() {
-        floyd();
-        return 0;
-    }
-    ```
-    Note that `floyd` is defined as a separate function and can be exported.
-
-2. Compile the C code using the most recent version of the [Emscripten compiler frontend](https://emscripten.org/docs/tools_reference/emcc.html):
-    ```bash
-    emcc --no-entry -s EXPORTED_FUNCTIONS=_floyd -o floyd.wasm floyd.c
-    ```
-    > The exported functions must be prefixed by `_`. If you reference that function in, for example, the Java code, the exported name should not contain the underscore.
-
-    It produces a standalone file _floyd.wasm_ in the current working directory.
-
-3. Add dependencies. The GraalVM SDK Polyglot API can be easily added as a Maven dependency to your Java project.
-The GraalWasm artifact should be on the Java module or class path too. Add the following set of dependencies to the project configuration file (_pom.xml_ in the case of Maven).
-
-    - To add the Polyglot API:
-        ```xml
-        <dependency>
-            <groupId>org.graalvm.polyglot</groupId>
-            <artifactId>polyglot</artifactId> 
-            <version>${graalwasm.version}</version>
-        </dependency>
-        ```
-    - To add GraalWasm:
-        ```xml
-        <dependency>
-            <groupId>org.graalvm.polyglot</groupId>
-            <artifactId>wasm</artifactId> 
-            <version>${graalwasm.version}</version>
-            <type>pom</type>
-        </dependency>
-        ```
-
-4. Now you can embed this WebAssembly function in a Java application, for example:
-
-    ```java
-    import org.graalvm.polyglot.*;
-    import org.graalvm.polyglot.io.ByteSequence;
-
-    // Load the WebAssembly contents into a byte array
-    byte[] binary = Files.readAllBytes(Path.of("path", "to", "wasm", "file", "floyd.wasm"));
-
-    // Setup context
-    Context.Builder contextBuilder = Context.newBuilder("wasm").option("wasm.Builtins", "wasi_snapshot_preview1");
-    Source.Builder sourceBuilder = Source.newBuilder("wasm", ByteSequence.create(binary), "example");
-    Source source = sourceBuilder.build();
-    Context context = contextBuilder.build();
-
-    // Evaluate the WebAssembly module
-    context.eval(source);
-
-    // Execute the floyd function
-    context.getBindings("wasm").getMember("example").getMember("_initialize").executeVoid();
-    Value mainFunction =context.getBindings("wasm").getMember("example").getMember("floyd");
-    mainFunction.execute();
-    context.close();
-    ```
-
-5. Compile and run this Java application with Maven as usual.
