+# pyLSA
+
+A simple server statistics agent for Linux. Serves statistics over HTTP. 
+The goal is to keep it small and not require anything but the Python 
+standard libraries.
+
+## Current status
+
+**In development.**  Most is already there, but it still needs stuff 
+like configuration file reading, authentication, etc.
+
+## How does it work?
+
+PySFX is used to create a self-extracting 'transparent' installer that
+compiles psutil locally (without installing it system-wide), and then
+puts all the files for pyLSA (including your config!) in place. It
+automatically starts pyLSA afterwards, and if you run the installer
+again, it'll detect that pyLSA is already installed, and run the
+existing installation.
+
+## How can I use it?
+
+1. (in the future) Modify the `pylsa.conf` file in the `installer/`
+directory.
+2. Run `build.sh`.
+3. Upload the created `pylsa_sfx.py` file to any server that you'd like
+to run your statistics agent on.
+4. Run the SFX on each of those servers. If you are root, it will create
+an unprivileged user for PyLSA and run it as that user. If you are an
+unprivileged user, it will run it as your user. Future attempts to start
+pyLSA using the installer will behave the same.
+5. Done!
