+
+## Gradle properties
+
+There are a lot of properties configured in `gradle.properties` which we strongly recommend
+being left as they are unless you have a specific problem with the build process.
+
+There are a few gradle properties you might want to set on the command line with the
+`-P` flag when building a version of Jalview with specific requirements:
+
+#### `JAVA_VERSION`
+This changes the *target* java bytecode version
+> NOTE that you will need to use a Java 11 (or greater) JDK Java compiler to build
+Jalview for any byte-code target version.
+
+Valid values are `11` and `1.8`.
+
+e.g.
+
+```bash
+gradle shadowJar -PJAVA_VERSION=1.8
+```
+
+When using `-PJAVA_VERSION=1.8` the libraries from `j8lib` (instead of `j11lib`) will be used in the compile
+and runtime classpath and also used in the `makeDist` build step. Where a Java version of `11` is used in folder and file names, it will
+instead use `1.8`. Also if you are building installer packages with *install4j* the
+package builder will look for JRE 1.8 bundles to package in the installers.
+
+> Note that continued development of Jalview will assume a Java 11+ runtime environment,
+the 2.11.0 release will run under a Java 1.8 JRE with a few minor features disabled.
+
+#### `CHANNEL`
+This changes the `appbase` setting in `getdown.txt` (`appbase` is where the getdown launcher
+looks to see if there's an updated file) to point to a particular Jalview
+channel. Expected values are `FILE`, `STABLE`, `DEVELOPMENT`, or a specific version
+of Jalview like `2.11` or `2.10.5`.
+
+A value of `FILE` behaves differently to the other expected values and will use a local
+file-system scheme URI instead of a Jalview release channel. This `file:` scheme URI
+uses an absolute path to the `getdown/website/<JAVA_VERSION>`
+
+On a regular development machine, this property will default to `LOCAL`.
+
+e.g.
+```bash
+gradle getdown -PCHANNEL=DEVELOPMENT
+```
+
+#### `MEDIA_TYPES`
+If you are building *install4j* installers (requires *install4j* to be installed) then this property specifies a comma-separated
+list of media types (i.e. platform specific installers) *install4j* should actually build.
+
+Currently the valid values are
+`linuxDeb`,
+`linuxRPM`,
+`macosArchive`,
+`unixArchive`,
+`unixInstaller`,
+`windows`
+
+The default value is all of them.
+
+e.g.
+```bash
+gradle installers -PJAVA_VERSION=1.8 -PMEDA_TYPE=macosArchive
+```
+
+To get an up-to-date list of possible values, you can run
+
+```bash
+perl -n -e 'm/^\s*<(\w+)[^>]*\bmediaFileName=/ && print "$1\n";' utils/install4j/install4j_template.install4j | sort -u
+```
+in the `jalview` root folder.
