 When using a Docker image as a reference, it's important to specify the digest of the image to ensure reproducibility, since a tag could be reassigned to a different image.
 
+### Paths Inside Docker Image
+
+During the build, paths from the source of the build as well as the location of the cargo registry could be saved into WASM, which affects reproducibility. Therefore, we need to ensure that everyone uses the same paths inside the Docker image. We propose using the following paths:
+- `/home/near/code` - Mounting volume from the host system containing the source code.
+- `/home/near/.cargo` - Cargo registry.
+
 #### Cargo.lock
 
 It is important to have `Cargo.lock` inside the source code snapshot to ensure reproducibility. Example: https://github.com/near/core-contracts.
