+# Find System-wide Config File For User
+
+The `jj` CLI can be configured in a couple different places. When I recently
+ran a `jj config` command, I was curious where specifically it was getting set.
+Those changes didn't appear in the repo's config (`./.jj/repo/config.toml`).
+That makes sense since it would only apply to that repo. So, where is the
+system-wide config file?
+
+The following commond shows where on your machine it is located.
+
+```bash
+$ jj config path --user
+/Users/jbranchaud/Library/Application Support/jj/config.toml
+```
+
+Now, the next time I set a config like this:
+
+```bash
+$ jj config set --user ui.paginate never
+```
+
+or want to check what other config options are set to, I can visit that path
+and take a look.
