-TODO: filter not done
+# Upgrade your AUR packages in parallel
+
+Building is slow, downloading is also slow. Why not build everything in parallel to overlap CPU-heavy tasks, Network-heavy tasks, and IO-heavy tasks?
+
+## Configure
+
+Modify config.sh, and set `aurpar_config_threads`, `aurpar_config_aur_manager` and `aurpar_aur_user`. 
+
+You may have a look at other options below, but I don't think you're interested in them. 
+
+## Usage
+
+```bash
+sudo ./aur-parallel-upgrade.sh
+```
+
+## FAQ
+
+- Multiple tasks printing texts at the same time and my terminal messed up!
+
+If you want to avoid the cross-talking, please remove `--line-buffer` from `aur-parallel-upgrade.sh`.
