 ## Code of conduct
 
@@ -36,9 +36,63 @@ covers the project. Feel free to contact the maintainers if that's a concern.
 We use GitHub issues to track public bugs. Report a bug by [opening a new
 issue](https://github.com/jesseduffield/lazygit/issues/new); it's that easy!
 
+## Go
+
+This project is written in Go. Go is an opinionated language with strict idioms, but some of those idioms are a little extreme. Some things we do differently:
+
+1. There is no shame in using `self` as a receiver name in a struct method. In fact we encourage it
+2. There is no shame in prefixing an interface with 'I' instead of suffixing with 'er' when there are several methods on the interface.
+3. If a struct implements an interface, we make it explicit with something like:
+
+```go
+var _ MyInterface = &MyStruct{}
+```
+
+This makes the intent clearer and means that if we fail to satisfy the interface we'll get an error in the file that needs fixing.
+
+## Internationalisation
+
+Boy that's a hard word to spell. Anyway, lazygit is translated into several languages within the pkg/i18n package. If you need to render text to the user, you should add a new field to the TranslationSet struct in `pkg/i18n/english.go` and add the actual content within the `EnglishTranslationSet()` method in the same file. Although it is appreciated if you translate the text into other languages, it's not expected of you (google translate will likely do a bad job anyway!).
+
+## Debugging
+
+The easiest way to debug lazygit is to have two terminal tabs open at once: one for running lazygit (via `go run main.go -debug` in the project root) and one for viewing lazygit's logs (which can be done via `go run main.go --logs` or just `lazygit --logs`).
+
+From most places in the codebase you have access to a logger e.g. `gui.Log.Warn("blah")`
+
+If you find that the existing logs are too noisy, you can set the log level with e.g. `LOG_LEVEL=warn go run main.go -debug` and then only use `Warn` logs yourself.
+
+If you keep having to do some setup steps to reproduce an issue, read the Testing section below to see how to create an integration test by recording a lazygit session. It's pretty easy!
+
+If you want to trigger a debug session from VSCode, you can use the following snippet. Note that the `console` key is, at the time of writing, still an experimental feature.
+
+```jsonc
+// .vscode/launch.json
+{
+  "version": "0.2.0",
+  "configurations": [
+    {
+      "name": "debug lazygit",
+      "type": "go",
+      "request": "launch",
+      "mode": "auto",
+      "program": "main.go",
+      "args": [
+        "--debug"
+      ],
+      "console": "externalTerminal" // <-- you need this to actually see the lazygit UI in a window while debugging
+    }
+  ]
+}
+```
+
+## Testing
+
+Lazygit has two kinds of tests: unit tests and integration tests. Unit tests go in files that end in `_test.go`, and are written in Go. Lazygit has its own integration test system where you can build a sandbox repo with a shell script, record yourself doing something, and commit the resulting repo snapshot. It's pretty damn cool!

 ## Creating a new test
 
 To create a new test:
-1) Copy and paste an existing test directory and rename the new directory to whatever you want the test name to be. Update the test.json file's description to describe your test.
-2) Update the `setup.sh` any way you like
-3) If you want to have a config folder for just that test, create a `config` directory to contain a `config.yml` and optionally a `state.yml` file. Otherwise, the `test/default_test_config` directory will be used.
-4) From the lazygit root directory, run:

 ```
-5) Feel free to re-attempt recording as many times as you like. In the absence of a proper testing framework, the more deliberate your keypresses, the better!
-6) Once satisfied with the recording, stage all the newly created files: `test.json`, `setup.sh`, `recording.json` and the `expected` directory that contains a copy of the repo you created.

 Feel free to create a hierarchy of directories in the `test/integration` directory to group tests by feature.
 
+## Sandboxing
+
+The integration tests serve a secondary purpose of providing a setup for easy sandboxing. If you want to run a test in sandbox mode (meaning the session won't be recorded and we won't create/update snapshots), go:
+
+```
+MODE=sandbox go test ./pkg/gui -run /<test name>

 If you think this process can be improved, let me know! It shouldn't be too hard to change things.
