 ## Building P4Python from Source
 
-  1. Download the r23.1 Perforce C++ API from the Perforce FTP site at
-     "ftp://ftp.perforce.com/perforce". The API archive is located
-     in release and platform-specific subdirectories.
+  1. Download the corresponding Perforce C++ API (e.g. if you trying to build P4Python 2023.1, download the r23.1 P4API) from
+     https://ftp.perforce.com/perforce. The API archive is located in release and platform-specific subdirectories.
 
-     Under Linux the p4api is named p4api-glib<GLIBVER>-openssl<SSLVER>.tgz\
-     			 Note that setup.py will download the correct p4api automatically from
-           ftp.perforce.com if you do not provide an --apidir parameter to the 
-           setup.py "build" command.
+     Under Linux, the p4api is named _p4api-glib\<GLIBVER>-openssl\<SSLVER>.tgz_

      Mac OS X users should get the API from the relevant platform directory e.g.
-     "**bin.macosx1010x86_64**" or "**bin.macosx12arm64**". The p4api is named
-     p4api-openssl<SSLVER>.tgz
+     "**bin.macosx1015x86_64**" or "**bin.macosx12arm64**".\
+     The p4api is named _p4api-openssl\<SSLVER>.tgz_
 
      Under Windows the p4api needs to match your compiler, build type (static 
      or dynamic) and SSL version.  for instance:
-
-	   "**p4api_vs2010_static_openssl1.1.1.zip**" or\
-	   "**p4api_vs2015_dyn_openssl1.0.2.zip**"
+	   "**p4api_vs2019_static_openssl3.zip**" or "**p4api_vs2019_dyn_openssl3.zip**"
 
          Note: 32-bit builds of P4Python require a 32-bit version of the
                C++ API and a 32-bit version of Python. 64-bit builds of
