+# midmesg
+**Mi**cro **dmesg** is a lighterweight alternative to dmesg.
+
+## Dependencies
+- **midmesg** should work perfectly fine on both musl libc and glibc.
+- **midmesg** requires header files for your Linux kernel. 
+
+Your Linux distribution should bundle them in a package named `linux-headers` or something similar to that.
+
+## Installation
+After you've cloned the Git repository, use these commands to compile and install **midmesg**.
+```
+make
+doas make install
+```
+
+To uninstall **midmesg**, use `doas make uninstall`.
+
+## Tasks
+- find some way to retain logs
+According to the [klogctl(3)](http://man.he.net/?topic=klogctl&sections=3) man page:
+
+> Bytes read from the log disappear from the log buffer:
+> the information can be read only once.
+
+- use a built-in pager instead of printing logs to the terminal or hoping that `less` exists on the system
