-### Updating from version 1.x to 2.x
-
-With release 2.0 we aligned the convention of the plugin having the same name as the command it contributes (in our
-case, `java`). This change mostly affects you in the way you update your plugin. If you have the version 1.x installed,
-you will need to uninstall the old version first by using the command: `cf uninstall-plugin JavaPlugin`. You know you
-have the version 1.x installed if `JavaPlugin` appears in the output of `cf plugins`.
-
-### Permission Issues
-
-On Linux and macOS, if you get a permission error, run `chmod +x [cf-cli-java-plugin]` (replace `[cf-cli-java-plugin]`
-with the actual binary name you will use, which depends on the OS you are running) on the plugin binary. On Windows, the
-plugin will refuse to install unless the binary has the `.exe` file extension.
