+Tool Command Language (TCL) Transport Layer Security (TLS) Extension
+
+Intro
+=====
+
+This package provides an extension which implements Secure Socket Layer (SSL)
+and Transport Layer Security (TLS) over Transmission Control Protocol (TCP)
+network communication channels. It utilizes either the OpenSSL or LibreSSL
+software library.
+ 
+Version 2.0 also provides a cryptography library providing TCL scripts access
+to the crypto capabilities of the OpenSSL library.
+
+
+Description
+===========
+
+This extension works by creating a layered TCL Channel on top of an existing
+bi-directional channel created by the TLS socket command. All existing socket
+functionality is supported, in addition to several new options. Both client
+and server modes are supported.
+
+
+Documentation
+=============
+
+See the doc directory for the full usage documentation.
+
+
+Compatibility
+=============
+
+This package requires TCL 8.5 or later.
+
+This package is compatible with:
+- OpenSSL v1.1.1 or later. See (http://www.openssl.org/
+- LibreSSL (TBD version)
+
+
+Installation
+============
+
+This package uses the Tcl Extension Architecture (TEA) to build and install on
+any supported Unix, Mac, or MS Windows system. Either the OpenSSL or LibreSSL
+software libraries must be built and available prior to building TCL TLS.
+
+UNIX and Linux
+--------------
+
+The standard TEA config, make and install process is supported.
+
+	$ cd tcltls
+	$ ./configure --enable-64bit --enable-deterministic --with-builtin-dh-params-size=2048
+	$ make
+	$ make test
+	$ make install
+
+The supported configure options include all of the standard TEA configure script
+options, plus:
+
+  --disable-tls1          disable TLS1 protocol
+  --disable-tls1_1        disable TLS1.1 protocol
+  --disable-tls1_2        disable TLS1.2 protocol
+  --disable-tls1_3        disable TLS1.3 protocol
+  --enable-deterministic  enable deterministic DH parameters
+  --enable-ssl-fastpath   enable using the underlying file descriptor for talking directly to the SSL library
+  --enable-hardening      enable hardening attempts
+  --enable-static-ssl     enable static linking to the SSL library
+  --with-builtin-dh-params-size=<bits>	specify the size of the built-in, precomputed, DH params
+
+If either TCL or OpenSSL are installed in non-standard locations, the following
+configure options are available. For all options, see ./configure --help.
+
+  --with-tcl=<dir>			path to where tclCondig.sh file resides
+  --with-tclinclude=<dir>		directory containing the public Tcl header files
+  --with-openssl-dir=<dir>		path to root directory of OpenSSL or LibreSSL installation
+  --with-openssl-includedir=<dir>	path to include directory of OpenSSL or LibreSSL installation
+  --with-openssl-libdir=<dir>		path to lib directory of OpenSSL or LibreSSL installation
+  --with-openssl-pkgconfig=<dir>	path to root directory of OpenSSL or LibreSSL pkgconfigdir
+
+
+MacOS
+-----
+
+The standard TEA installation process is supported. Use the --with-tcl option
+to set the TCL path if the ActiveState or other non-Apple version of TCL is to
+be used.
+
+	$ cd tcltls
+	$ ./configure --with-tcl=/Library/Frameworks/Tcl.framework/
+	$ make
+	$ make test
+	$ make install
+
+
+Windows
+-------
+
+If installing with MinGW, use the TEA build process. If using MS Visual C
+(MSVC), see the win/README.txt file for the installation instructions.

-
-TLS (aka SSL) Channel - can be layered on any bi-directional Tcl_Channel.
-
-Both client and server-side sockets are possible, and this code should work
-on any platform as it uses a generic mechanism for layering on SSL and Tcl.
-
-Full filevent sematics should also be intact - see tests directory for
-blocking and non-blocking examples.
-
-The current release is TLS 1.7, with binaries built against OpenSSL 1.1.1.
-For best security and function, always compile from source with the latest
-official release of OpenSSL (http://www.openssl.org/).
-
-TLS 1.7 and newer require Tcl 8.4.0+, older versions may be used if older
-versions of Tcl need to be used.
-
-TclTLS requires OpenSSL or LibreSSL in order to be compiled and function.
