-# End User Instructions:
-
-If you simply want to download and run the program, please follow these instructions.
-
-## Download the latest sdrtrunk release for your operating system
- 
+## Download the Latest Release
 All release versions of sdrtrunk are available from the [releases](https://github.com/DSheirer/sdrtrunk/releases) tab.
 
 * **(alpha)** These versions are under development feature previews and likely to contain bugs and unexpected behavior.
 * **(beta)** These versions are currently being tested for bugs and functionality prior to final release.
 * **(final)** These versions have been tested and are the current release version.
 
-## Unzip the release
-
-Use 7-zip or any zip utility to unzip the release file
-
-## Start the application
-
-Once unzipped, open a command prompt to where you unzipped the release.  Change to the **/bin** directory and use the launch script to start the application:
-* **Windows** sdr-trunk.bat
-* **Linux/OSX** ./sdr-trunk
-
-## Optional - P25/DMR Audio
-If you're using sdrtrunk with a P25 or DMR radio system, you'll need to compile and include the [JMBE](https://github.com/DSheirer/sdrtrunk/wiki/JMBE) digital audio library.
-
-In Version 0.5.0 and higher, the SDRTrunk application has support for building the JMBE library.  On the menu, choose **View >> User Preferences** and then click the **Decoder >> JMBE Audio Library** tab.
-
-For versions prior to Version 0.5.0, the [JMBE](https://github.com/DSheirer/sdrtrunk/wiki/JMBE) wiki page contains instructions for downloading the JMBE audio library source code and compiling the JMBE library.  Once you have compiled the library, launch the sdrtrunk application.  From the menu bar, choose **View >> Preferences**.  In the **JMBE Audio Codec** section, update the path to where your compiled JMBE library is located.  Any channels that are started after you set the path will be able to produce P25 audio.
+## Download Nightly Software Build
+The [nightly](https://github.com/DSheirer/sdrtrunk/releases/tag/nightly) release contains current builds of the software 
+for all supported operating systems.  This version of the software may contain bugs and may not run correctly.  However, 
+it let's you preview the most recent changes and fixes before the next software release.  **Always backup your 
+playlist(s) before you use the nightly builds.**  Note: the nightly release is updated each time code changes are 
+committed to the code base, so it's not really 'nightly' as much as it is 'current'.
 
 ## Minimum System Requirements
 * **Operating System:** Windows (~~32 or~~ 64-bit), Linux (~~32 or~~ 64-bit) or Mac/Linux (64-bit, 10.14 or higher)
 * **CPU:** 4-core
 * **RAM:** 8GB or more (preferred).  Depending on usage, 4GB may be sufficient.
-
-# Developer Instructions:
-
-If you're interested in modifying and/or compiling the source code, please follow these instructions to use gradle to compile the code. 
-
-## Build the project
-sdrtrunk uses the gradle build system. This requires **OpenJDK 17** or higher installed on your local computer.  
-
-### OpenJDK
-There are many vendors producing OpenJDK distributions.  A few that I use are:
-* [Azul Zulu OpenJDK](https://www.azul.com/downloads/?package=jdk)
-* [Bellsoft Liberica OpenJDK](https://bell-sw.com/pages/downloads/#/java-17-lts%20/%20current)
-* [SDKMAN](https://sdkman.io/) - Linux Only
-
-Use the gradle wrapper to build the source code:
-
-### Linux
-```
-./gradlew clean build
-```
-### Windows
-```
-gradlew.bat clean build
-```
-
-The **/build/distributions** folder will contain the zip file of the compiled program.  Unzip it and launch the program from the scripts in the **/bin** directory.
-
-## Run the Application (from Gradle)
-
-### Linux
-```
-./gradlew clean run
-```
-### Windows
-```
-gradlew.bat clean run
-```
-
-
-## Development
-All dependencies/versions are controlled from build.gradle.
-To change the new release version tag of artifact - change property:
-```
-version = '0.5.0'
-```

+Auto-generating Java code from SDRPlay API using jextract.
+
+Note: the api headers in the 3.11 folder are equivalent to the 3.08 headers.  The only
+difference from the 3.07 headers is the addition of the boolean 'valid' flag to DeviceT structure.
+
+1. Download JDK19 compatible build of jextract JDK: https://jdk.java.net/jextract/
+2. If generating on windows platform, modify the sdrplay_api.h to remove the windows
+   pieces of the file.  Specifically:
+2a. Comment out these lines but leave the *HANDLE typedef:
+
+//#if defined(_M_X64) || defined(_M_IX86) || defined(_M_ARM64)
+//#include "windows.h"
+//#elif defined (__GNUC__)
+typedef void *HANDLE;
+//#endif
+
+//#ifndef _SDRPLAY_DLL_QUALIFIER
+//#if !defined(STATIC_LIB) && (defined(_M_X64) || defined(_M_IX86) || defined(_M_ARM64))
+//#define _SDRPLAY_DLL_QUALIFIER __declspec(dllimport)
+//#elif defined(STATIC_LIB) || defined(__GNUC__)
+//#define _SDRPLAY_DLL_QUALIFIER
+//#endif
+//#endif  // _SDRPLAY_DLL_QUALIFIER
+
+2b. Remove the '_SDRPLAY_DLL_QUALIFIER' from in front of the method declarations
+
+2c. Change the 3.11 version string to 3.08 either in the header file, or in the generated java class
+
+3. Open command prompt to the root source code where the generated files should be placed:
+..\SDRtrunk\sdrplay-api\src\main\java
+
+4. Generate the code:
+c:\Users\Denny\Downloads\jdk-19-ea2-panama\bin\jextract "C:\Users\Denny\git\sdrtrunk\sdrplay-api\api\v3_11\sdrplay_api.h" -l libsdrplay_api --source
+
+5. Do this for all versions of the API.

-##  Gradle start up script for UN*X
-##
+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
