## 16.3. Getting the Source

The PostgreSQL 13.15 sources can be obtained from the download section of our website: https://www.postgresql.org/download/. You should get a file named `postgresql-13.15.tar.gz` or `postgresql-13.15.tar.bz2`. After you have obtained the file, unpack it:

    gunzip postgresql-13.15.tar.gz
    tar xf postgresql-13.15.tar

(Use `bunzip2` instead of `gunzip` if you have the `.bz2` file. Also, note that most modern versions of `tar` can unpack compressed archives directly, so you don't really need the separate `gunzip` or `bunzip2` step.) This will create a directory `postgresql-13.15` under the current directory with the PostgreSQL sources. Change into that directory for the rest of the installation procedure.

You can also get the source directly from the version control repository, see Appendix I.
