+# Installation
+
+Copy these files from the fsqio repo:
+```
+src/python/fsqio/__init__.py
+src/python/fsqio/pants/__init__.py
+src/python/fsqio/pants/pom/*
+```
+
+You can delete `src/python/fsqio/pants/pom/BUILD` unless you're planning on writing tests for or publishing the pom-resolve; this means you don't need to put the deps in your 3rdparty file.
+
+Add this to your pants.ini:
+
+```
+# Note this is effectively requirements.txt for the pants environment, so we need the deps of
+# our build dependancies, see: https://github.com/pantsbuild/pants/issues/4001
