+## Building locally
+
+Build locally by passing the `dev` flag to it:
+
+``` shellsession
+$ stack build . --flag stackage-server:dev
+```
+
+Now, initially you need to run the cron job and create and populate the database:
+
+``` shellsession
+$ export PGSTRING=postgresql://postgres:password@localhost:5432/stackage
+$ stack exec stackage-server-cron
+```
+
+After this, try running in the stackage server:
+
+``` shellsession
+$ stack exec stackage-server
+```
