+building and installing dosemu2 from sources
+==============================================
+
+-> REQUIREMENTS for dosemu2:
+    - fdpp of the latest version, for now from git or from PPA:
+      https://code.launchpad.net/~dosemu2/+archive/ubuntu/ppa
+      of from COPR:
+      https://copr.fedorainfracloud.org/coprs/stsp/dosemu2/
+    - gcc >= 8.1 or clang >= 3.7.0
+    - glibc >= 2.20
+    - linux >= 3.16 for x86-64, >= 4.7 recommended.
+      With older version than 3.16 there may be some problems
+      with DPMI, especially make sure to not use 3.14 and 3.15.
+      linux >= 4.3 for i386.
+      linux >= 4.11 if you want to run 32bit dosemu under x86_64 kernel
+      with multilib environment (you likely don't want to do this).
+    - bison and flex
+    - SDL >= 2.0.6, >= 2.26.0 is required for copy/paste support.
+    - libslirp >= 4.1.0 recommended for networking
+    - json-c >= 0.13 recommended
+    - development libraries: Xext, slang, gpm, alsa, fluidsynth,
+      ladspa, libao can be used when available.
+
+This means that Ubuntu Focal or Fedora 31 are the minimum
+recommended systems.
+
+--------------------------------------------------------------------------
+1. Compile
+--------------------------------------------------------------------------
+
+First you should run:
+
+./autogen.sh
+
+Then either:
+
+./default-configure
+make
+
+or
+
+- create a seperate directory and run
+    $SRCDIR/configure (or $SRCDIR/default-configure; see below)
+    make
+  in that directory.
+
+- If you want dosemu2 executable with debug info, then add -d parameter
+  to default-configure on the previous step. But expect the debug build
+  to work considerably slower than the release build!
+
+- sudo make install
+
+You can now start dosemu2 by typing "dosemu". But if you didn't install
+comcom32, dosemu2 may not find command.com. We recommend to install
+the pre-compiled comcom32 package either from PPA or COPR. Or you can
+instead download it from here:
+https://dosemu2.github.io/comcom32/files/comcom32.zip
+unzip to ~/.dosemu/drive_c and symlink as command.com.
+You may not want to build comcom32 from sources unless you know how
+to install djgpp.
