#Verify the Installation Packages

You must verify each package that you've downloaded:

For the Core Package:

gpg --verify <core package signature file> <core package>

Example:

gpg --verify acp-4.0.0.tgz.sig acp-4.0.0.tgz

If you downloaded the Extensions Package:

gpg --verify <extensions package signature file> <extensions package>

Example:

gpg --verify acp-extensions-4.0.0.tgz.sig acp-extensions-4.0.0.tgz

The normal output should display "Good signature" information for each verification.

#Extensions Package Documentation

If you downloaded the Extensions Package, you need to extract its documentation before proceeding with the Core Package installation:

tar -xvf acp-extensions-4.0.0.tgz

Refer to the extracted documentation for information on how to use the Extensions Package alongside the Core Package.
