+# openwrt-buildroot-nix
+
+This provides a Nix environment for [OpenWRT Buildroot](https://openwrt.org/docs/guide-developer/toolchain/use-buildsystem).
+
+## Usage
+
+```
+nix develop git+https://git.clerie.de/clerie/openwrt-buildroot-nix.git
+```
+
+## Troubleshooting
+
+### Dependencies cannot be found randomly
+
+OpenWRT buildroot seem to hardcode paths it found for dependencies.
+If the nix environment gets changed these paths change too.
+Clean the build environment to get it working again:
+
+```
+make dirclean
+```
