+Introduction
+============
+
+This is GNU Bash, version 5.2. Bash is the GNU Project's Bourne
+Again SHell, a complete implementation of the POSIX shell spec,
+but also with interactive command line editing, job control on
+architectures that support it, csh-like features such as history
+substitution and brace expansion, and a slew of other features. 
+For more information on the features of Bash that are new to this
+type of shell, see the file `doc/bashref.texi'.  There is also a
+large Unix-style man page.  The man page is the definitive description
+of the shell's features. 
+
+See the file POSIX for a discussion of how the Bash defaults differ
+from the POSIX spec and a description of the Bash `posix mode'.
+
+There are some user-visible incompatibilities between this version
+of Bash and previous widely-distributed versions, bash-4.4, bash-5.0,
+and bash-5.1. For details, see the file COMPAT.  The NEWS file tersely
+lists features that are new in this release. 
+
+Bash is free software, distributed under the terms of the [GNU] General
+Public License as published by the Free Software Foundation,
+version 3 of the License (or any later version).  For more information,
+see the file COPYING. 
+
+A number of frequently-asked questions are answered in the file
+`doc/FAQ'. (That file is no longer updated.)
+
+To compile Bash, type `./configure', then `make'.  Bash auto-configures
+the build process, so no further intervention should be necessary.  Bash
+builds with `gcc' by default if it is available.  If you want to use `cc'
+instead, type
+
+	CC=cc ./configure
+
+if you are using a Bourne-style shell.  If you are not, the following
+may work:
+
+	env CC=cc ./configure
+
+Read the file INSTALL in this directory for more information about how
+to customize and control the build process.  The file NOTES contains
+platform-specific installation and configuration information.
+
+If you are a csh user and wish to convert your csh aliases to Bash
+aliases, you may wish to use the script `examples/misc/alias-conv.sh'
+as a starting point.  The script `examples/misc/cshtobash' is a
+more ambitious script that attempts to do a more complete job.
+
+Reporting Bugs
+==============
+
+Bug reports for bash should be sent to:
+
+	bug-bash@gnu.org
+
+using the `bashbug' program that is built and installed at the same
+time as bash.
+
+The discussion list `bug-bash@gnu.org' often contains information
+about new ports of Bash, or discussions of new features or behavior
+changes that people would like.  This mailing list is also available
+as a usenet newsgroup: gnu.bash.bug. 
+
+When you send a bug report, please use the `bashbug' program that is
+built at the same time as bash.  If bash fails to build, try building
+bashbug directly with `make bashbug'.  If you cannot build `bashbug',
+please send mail to bug-bash@gnu.org with the following information:
+
+	* the version number and release status of Bash (e.g., 2.05a-release)
+	* the machine and OS that it is running on (you may run
+	  `bashversion -l' from the bash build directory for this information)
+	* a list of the compilation flags or the contents of `config.h', if
+	  appropriate
+	* a description of the bug
+	* a recipe for recreating the bug reliably
+	* a fix for the bug if you have one!
+
+The `bashbug' program includes much of this automatically.
+
+Questions and requests for help with bash and bash programming may be
+sent to the help-bash@gnu.org mailing list.
+
+If you would like to contact the Bash maintainers directly, send mail
+to bash-maintainers@gnu.org.
+
+While the Bash maintainers do not promise to fix all bugs, we would
+like this shell to be the best that we can make it.
+
+Other Packages
+==============
+
+This distribution includes, in examples/bash-completion, a recent version
+of the `bash-completion' package, which provides programmable completions
+for a number of commands. It's available as a package in many distributions,
+and that is the first place from which to obtain it.
+
+The latest version of bash-completion is always available from
+https://github.com/scop/bash-completion.
+
+If it's not a package from your vendor, you may install the included version.
+
+Enjoy!
