+## Build/Install From Source
+
+Make sure you have at least:
+- C compiler
+- libc
+- make
+
+Then take a look if you need to tune anything in the Makefile.
+
+Then to build do:
+```sh
+make clean
+make
+```
+
+And to install:
+```sh
+make install
+```
+
+Or install even simpler:
+```sh
+tar -C /usr/local -xzf path/to/dist/your-build.tgz -- bin
+```
+
