+# Local IPFS Server
+
+`py-ipfs-httpclient` requires a live local server to run its 
+functional tests.
+
+## Installation
+
+To install it, follow the [official instructions](https://docs.ipfs.io/install/command-line/),
+then finish with some [local configuration](configure.sh):
+
+	$ ./configure.sh
+
+The above script is run once after installing.
+
+## Running Tests
+
+You can run unit tests without a live server; `pytest` will skip
+over the functional tests when our fixtures detect the server
+isn't running.
+
+In a separate terminal, start IPFS with:
+
+	$ ./run.sh
+
+Stop it with Ctrl+C. You can keep it running across multiple
+executions of the functional test suite.
