+# Specify Default Team And App For Project
+
+Typically when you run commands with the Heroku CLI you'll need to specify the
+name of the app on Heroku you're targeting with the `--app` flag. However, to
+first see the names of the apps you may want to run `heroku apps` (or `heroku
+list`). That will list the apps for your default team.
+
+If you need to see apps for a different team (i.e. organization), you'll need to
+specify that team either with the `--team` flag or by setting that as an
+environment variable.
+
+Here I do the latter in an `.envrc` file:
+
+```
+# Heroku
+export HEROKU_ORGANIZATION=visualmode
+```
+
+Once that is set and the environment reloaded, running `heroku apps` will show
+the apps specific to that team on Heroku.
+
+Similarly, if you want to set a default app for your project so that you don't
+have to always specify the `--app` flag, you can update your `.envrc`
+accordingly.
+
+```
+# Heroku
+export HEROKU_ORGANIZATION=visualmode
+export HEROKU_APP=my-app
+```
+
+I had a hard time finding official documentation for this which is why I'm
+writing this up here. I've manually verified this works with my own team and
+app.
