 ## Usage
 
-Use `#!/usr/bin/env compilescript` as shebang and write the compiler arguments
-in the second line with the prefix: `//compilescript:`.
-
-You can delete old cache files with `--cleanup`.
-
-### Example
-
-```C++
-#!/usr/bin/env compilescript
-//compilescript: -Wall -pedantic -Wextra
-
-#include <iostream>
-
-using std::cout;
-
-int main(int argc, char *argv[])
-{
-    cout << "Hello world!\n";
-    cout << argv[1] << '\n';
-}
-```
-
-## Configuration
-
-The configuration file is in `${XDG_CONFIG_HOME}/compilescript.cfg`. It will be
-generated on first run.
-
-### Example config
-
-```CFG
-compiler = "g++";
-clean_after_hours = 720;
-cache_dir = "/home/user/.cache/compilescript";
-```
+Have a look at the [manpage](https://schlomp.space/tastytea/compilescript/src/branch/master/compilescript.1.adoc).

+== NAME
+
+compilescript - allows you to execute files from compiled languages as scripts.
+
+== SYNOPSIS
+
+*compilescript* [_file_|_--cleanup_] [_arguments_]
+
+== DESCRIPTION
+
+compilescript allows you to execute files from compiled languages as scripts.
+By default it uses g++.
+
+It compiles the source file, stores the binary in
+`${XDG_CACHE_HOME}/compilescript/` and executes it. If the binary in cache is
+newer than the source file, the compilation is skipped.
+
+Use `#!/usr/bin/env compilescript` as shebang and write the compiler arguments
+in the second line with the prefix: `//compilescript:`.
+
+The configuration file is in `${XDG_CONFIG_HOME}/compilescript.cfg`. It will be
+generated on first run.
+
+== OPTIONS
+
+[format="csv",frame="none",grid="none",cols="2"]
+|======
+*--cleanup*,Delete old cache files.

+
+== EXAMPLE
+
+=== Example script
+
+[source,cpp]
+----
+#!/usr/bin/env compilescript
+//compilescript: -Wall -pedantic -Wextra
+
+#include <iostream>
+
+using std::cout;

+
+== FILES
+
+* Configuration file: `${XDG_CONFIG_HOME}/compilescript.cfg`
+* Cache: `${XDG_CACHE_HOME}/compilescript/`
+
+`${XDG_CONFIG_HOME}` is usually `~/.config` and `${XDG_DATA_HOME}` is usually
+`~/.cache`
