+## Configuring the amount of dir levels
+
+By default only the last three directories are shown in the prompt. The amount of
+levels can be configured by setting `LAMBDA_MOD_N_DIR_LEVELS` before loading the prompt:
+
+``` zsh
+# ~/.zshrc
+export LAMBDA_MOD_N_DIR_LEVELS=10
+
+# load `lambda-mod` and `oh-my-zsh`
+```
