-What is gcc-config?
--------------------
-
-gcc-config allows Gentoo users to switch active gcc safely
-and allows querying facts about installed toolchains.
-
-To switch active gcc while system runs:
-    $ gcc-config x86_64-pc-linux-gnu-8.1.0
-    $ gcc-config x86_64-pc-linux-gnu-7.2.0
-
-    Ideally changes should be visible instantly and atomically
-    without shell restart.
-
-To query where real gcc binaries are hiding:
-    $ gcc-config -B $(gcc-config -c)
-
-To parse a profile into TARGET and toolchain version:
-    $ gcc-config -S sparc64-unknown-linux-gnu-9.2.0

+# What is gcc-config?
+
+`gcc-config` allows Gentoo users to switch active gcc safely
+and allows querying facts about installed toolchains.
+
+## Usage
+
+To switch active `gcc` while system runs:
+
+```
+    $ gcc-config x86_64-pc-linux-gnu-8.1.0
+    $ gcc-config x86_64-pc-linux-gnu-7.2.0
+```
+
+Ideally changes should be visible instantly and atomically
+without shell restart.
+
+To query where real `gcc` binaries are hiding:
+
+```
+    $ gcc-config -B $(gcc-config -c)
+```
+
+To parse a profile into TARGET and toolchain version:
+
+```
+    $ gcc-config -S sparc64-unknown-linux-gnu-9.2.0
