I'm taking a look on this one.

Hi @matheusfd3! Thanks for reporting this issue. I've just tested the command on both linux and windows with Docker Desktop and it seems to be working correctly.

The error you're getting suggests that Docker can't find the Dockerfile in your current directory:

ERROR: failed to solve: failed to read dockerfile: open Dockerfile: no such file or directory

This typically occurs in two common scenarios:

1. The command is being executed from a directory that doesn't contain the Dockerfile
2. The Dockerfile has a different name (e.g., dockerfile in lowercase)

In the main branch the Dockerfile file name is correct so to resolve this, please verify:

• That you're running the command from the root directory of the project
• That the file is named exactly Dockerfile (case-sensitive)

If your Dockerfile has a different name, you can specify it using the -f flag:

docker buildx build --platform linux/amd64,linux/arm64 -t readme-ai --push -f ./your-dockerfile .

The command structure itself is correct for multi-architecture builds. Once you confirm the Dockerfile location and name, it should work as expected.

Let me know if you need any further assistance! If not, this issue can be closed @eli64s.
