+Example for compiling Ruby versions dependent on OpenSSL 1.1 via 
+[RVM][rvm].
+
+Ruby 2.4.x - 2.7.x require OpenSSL 1.1 which has been superseded
+on most operating systems.
+
+
+## Ruby >= 2.4.x (OpenSSL 1.1)
+
+Install the OpenSSL 1.1 dependency:
+
+```bash
+pacman -Sy openssl-1.1
+```
+
+Build with RVM:
+
+```bash
+CFLAGS+=" -I/usr/include/openssl-1.1" \
+LDFLAGS+=" -L/usr/lib/openssl-1.1 -lssl" \
+PKG_CONFIG_PATH=/usr/lib/openssl-1.1/pkgconfig \
+rvm install 2.7.7
+```
