+### Debugging Vimspector
+
+You can debug vimspector's python code using vimspector! We can use debugpy,
+from within Vim's embedded python and connect to it. Here's how:
+
+1. In one instance of vim, run the following to get debugpy to start listening
+   for us to connect: `:py3 __import__( 'vimspector', fromlist=[ 'developer' ]
+   ).developer.SetUpDebugpy()`
+
+2. In another instance of Vim, set a breakpoint in the vimspector python code
+   you want to debug and launch vimspector (e.g. `<F5>`). Select the `Python:
+   attach to vim` profile. This will attach to the debugpy running in the other
+   vim.
+
+3. Back in the first vim (the debuggee), trigger the vimspector code in
+   question, e.g. by starting to debug something else.
+
+4. You'll see it pause, and the 2nd vim (the debugger), you should be able to
+   step through and inspect as with any other python remote debugging.
+
+NB. It's also possible to debug the vimscript code using vimspector, but this
+requires unreleased vim patches and a fair amount of faff. You can always use
+`:debug` (see the help) for this though.

+
+If the debuggee is still running when stopping or resetting, then some debug

+

+`vimspector#Reset( { 'interactive': v:true } )`. If the debug adapter offers a
+choice as to whether or not to terminate the debuggee, you will be prompted to

+When using the [java debug server][java-debug-server], Vimspector supports the

+# Purpose
+
+This example comes with two example vimspector configs for the Go programming language.
+
+1) `run-cmd` will launch the main programme under `cmd/namestartswithvowel`.
+1) `test-current-file` will run the tests in the current file in debug mode.
+
+## Example use-cases
+
+### run-cmd
+
+* Open `cmd/namestartswithvowel/main.go`
+* Add a breakpoint somewhere within the programme
+* Start the debugger (`:call vimspector#Continue()` or your relevant keymapping)
+* Select the first launch configuration (`1: run-cmd`)
+
+### test-current-file
+
+* Open `internal/vowels/vowels_test.go`
+* Add a breakpoint somewhere within the test
+* Start the debugger (`:call vimspector#Continue()` or your relevant keymapping)
+* Select the second launch configuration (`2: test-current-file`)
+
+## Additional Configuration
+
+There are two additional configuration options specified under `run-cmd`; these parameters configure the maximum string/array size to be shown while debugging.
