+
+## Why this images
+
+1. If you need self-hosted remote development environment.
+2. If you want to be one terminal command away from coding in R.
+3. if you need isolated environment where you can work with R without polluting main environment.
+
+## Start
+
+```
+docker run --name space-1 -d -p 8020-8035:8020-8035 alnoda/r-workspace
+```
