+## Python editing
+
+PyCharm or IntelliJ IDEA seems to give the best Python editing experience. Make sure
+you build/run Anki first, as code completion depends on the build process to generate
+a bunch of files.
+
+Visual Studio Code + the Python extension does support code completion, but
+currently seems to frequently freeze for multiple seconds while pinning the CPU
+at 100%. Switching from the default Jedi language server to Pylance improves the
+CPU usage, but Pylance doesn't do a great job understanding the type annotations.
+
+## Rust editing
+
+Rust editor support is still fairly new, but currently Visual Studio Code + Rust
+Analyzer seems to be the least-bad option. Once Rust Analyzer is installed,
+you'll want to enable the options to expand proc macros, and run cargo check on
+startup.
+
+After running 'code rslib' from the project root, it may take Rust Analyzer a
+while to become ready - if you check the running processes on your machine you should
+see it running in the background for a while.
+
+## TypeScript editing
+
+Visual Studio Code seems to give the best experience. Use 'code ts' from the project
+root to start it up.
+
+IntelliJ IDEA works reasonably well, but doesn't seem to do as good a job at offering
+useful completions for things like i18n.TR.
