+# Django Postgres Lock
+
+A [Django](https://www.djangoproject.com/) management command which will run a command inside a
+Postgres lock, ensuring that only a single instance of the inner command will run.
+
+## Installation
+
+Using [pip](https://pip.pypa.io/):
+
+```console
+$ pip install django-postgres-lock
+```
+
+Edit your Django project's settings module, and add the application to ``INSTALLED_APPS``:
+
+```python
+INSTALLED_APPS = [
+    # ...
+    "postgres_lock",
+    # ...
+]
+```
+
+## Usage
+
+To run clearsessions with the default lock:
+
+```console
+$ ./manage.py command_lock -- ./manage.py clearsessions
+```
+
+To use a unique lock for this task:
+
+```console
+$ ./manage.py command_lock --name clearsessions -- ./manage.py clearsessions
+```
+
+To exit immediately if a lock can't be acquired:
+
+```console
+$ ./manage.py command_lock --try --name clearsessions -- ./manage.py clearsessions
+```
+
+To ignore a lock failure and return a successful exit code:
+
+```console
+$ ./manage.py command_lock --try --ignore-fail --name clearsessions -- ./manage.py clearsessions
+```
