The next step after creating the keypair and the revocation certificate is to publicize the public key. The simplest (more universally independent) way of start doing this is by exporting the public key. This is well explained in PGP & GPG - Email for the practical paranoid.
Again, I'll use the fictitious user John Smith to follow the export process.
Assume that the private and public keys have been successfully created.
Assume that the revocation certificate has already been created.
$ gpg --list-secret-key
/home/.../.gnupg/secring.gpg
------------------------------
sec 4096R/F50D9DFD 2014-07-08 [expires: 2015-07-08]
uid John Smith (Business Corp. HR Manager)
ssb 4096R/6CB8D3D2 2014-07-08
$ gpg --list-key
/home/.../.gnupg/pubring.gpg
------------------------------
pub 4096R/F50D9DFD 2014-07-08 [expires: 2015-07-08]
uid John Smith (Business Corp. HR Manager)
sub 4096R/6CB8D3D2 2014-07-08 [expires: 2015-07-08]
The export of the public key can be both in binary and ASCII format (--armor).
Each format may be more convenient for an specific purpose.
The export process is quiet:
$ gpg --output pubkey.jsmith@business.corp.gpg
--export "jsmith@business.corp"
$ gpg --output pubkey.jsmith@business.corp.gpg.asc --armor
--export "jsmith@business.corp"
But both output files can be located in the current directory.
The ASCII version can be seen as follows:
$ cat pubkey.jsmith@business.corp.gpg.asc

This completes the basic start up with GNUPG.
But it's advisable to hush to adjust some defaults.
