 The process of packaging a set of programs and files into a Docker Image requires a [Dockerfile](https://docs.docker.com/engine/reference/builder/), which can be thought of as recipe for building the Image.
 
 For an Extension to be properly managed and shareable, the Dockerfile it's created from should include relevant metadata[^2] via the following labels:
-- `LABEL permisions='{}'`
+- `LABEL permissions='{}'`
  - This can be used to set resource limits, including allowing access to specific components of the underlying hardware
  - This must be a valid JSON (use \ to break lines), which follows the configuration described in the [Docker Api](https://docs.docker.com/engine/api/v1.41/#tag/Container/operation/ContainerCreate)
  - For reference, existing permissions can be retrieved from a running Docker Container by running the command `docker inspect <container_name>`
