 # chronologger
 
-To run, do `go run .`
+Chronologger is a personal review app, built with Golang.
+
+# Development
+
+Start the application with hot module reloading using `make hmr`.
+
+Alternatively, if you don't need hot module reloading, you can just run `go run .` or `make start`
+
+## Known issues
+
+```
+(!) templ version check failed: failed to parse go.mod file: ~/chronologger/go.mod:3: invalid go version '1.21.0': must match format 1.23
+```
+To fix this, make sure you have at least the following version installed:
+```
+go install github.com/a-h/templ/cmd/templ@v0.2.543
+```
+You can test this by running `templ version`.
