Merge branch 'master' into 'master'

Make it compile on linux, explain how in README, and log warnings and errors to the stdout console

 # NTERA
 
-New Technology ERA
+New Technology ERA.
+
+This is a reimplementation of the engine that runs ERA games.
+
+# Linux
+
+## Compiling
+
+To compile on linux, you need dotnet 7.  Follow the instructions https://www.mono-project.com/download/stable/#download-lin
+
+For example, in Ubuntu do:
+
+    sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
+    echo "deb https://download.mono-project.com/repo/ubuntu stable-bionic main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list
+    sudo apt update
+
+Then install:
+
+    sudo apt install mono-devel nuget
+
+(Note that you need 'nuget' as well.)
+
+Now download the dependencies for NTERA:
+
+    nuget restore
+
+Build with:
+
+    msbuild
+
+# Running:
+
+You can run with:
+
+    ERA=/path/to/eragame mono NTERA/bin/Debug/NTERA.exe
+
+## Development
+
+For development, I recommend installing the optional monodevelop:
+
+    sudo apt install monodevelop
+    monodevelop NTERA.sln
