+# LogCapture
+`apprise.LogCapture()` allows you to capture all of the logging information within your program.  You may wish to relay the information to screen, or maybe you just want to have a look at it's contents when one or more notifications fail to be delivered.
+
+The class can capture information into a temporary (or permanent) log file, or you can just capture it straight into memory.  It's incredibly easy to use too.
+
+## Learn by Example
+### Capture to Memory
+**Your code changes from this:**
+```python
+import apprise
+
+# Instantiate our object
+apobj = apprise.Apprise()
+
+# add your configuration
+apobj.add('mailto://user:pass@example.com')
+apobj.add('kodi://kodi.example.com')
+
+# Send our notification
+apobj.notify(title="hello", body="world")
+```
+
+**To this:**
+```python
+import apprise
+
+# Instantiate our object
+apobj = apprise.Apprise()
+
+# add your configuration
+apobj.add('mailto://user:pass@example.com')
+apobj.add('kodi://kodi.example.com')
+
+# Prepare a LogCapture() that sets logging to INFO. This means your
+# logs will include all INFO, WARNING, ERROR, and CRITICAL entries
+with apprise.LogCapture(level=apprise.logging.INFO) as output:
+    # Send our notification
+    apobj.notify(title="hello", body="world")
+
+    # At this point of our code, we can have a look at our output
+    # to see all of the logging that surrounded our notification(s)
+    # Note that `output` is a StringIO object:
+    print(output.getvalue())
+```
+
+### Capture to File
+The class can write directly to memory (as you saw above) where content was written into a `io.StringIO` object.  You can also write content into a temporary file as well:
+```python
+# In this example:
+# - we write to a log file /tmp/apprise.tmp
+# - we only capture WARNING, ERROR, and CRITICAL entries
+# - we assume that `apobj` is an Apprise object already loaded with a few notification
+#   services.
+with apprise.LogCapture(path='/tmp/apprise.tmp', level=apprise.logging.WARNING) as output:
+    # Send our notification
+    apobj.notify(title="hello", body="world")
+
+    # At this point of our code, we can have a look at our output
+    # to see all of the logging that surrounded our notification(s)
+    # Note that `output` is a File object because we specified the `path` above
+    print(output.read())
+
+# What is VERY important to note is that whatever was specified with the `path=` above
+# entry (in this case /tmp/apprise.tmp) will no longer exist at this point (outside of the
+# `with` block).
+```
+
+If you want to write to a file and have it persist after your `with` block has completed, the syntax is very similar, you just need to add `delete=False` to the **LogCapture()** initialization like so:
+```python
+# In this example:
+# - we write to a log file /tmp/apprise.tmp
+# - we only capture WARNING, ERROR, and CRITICAL entries
+# - we assume that `apobj` is an Apprise object already loaded with a few notification
+#   services.
+with apprise.LogCapture(
+        path='/tmp/apprise.persistent', level=apprise.logging.WARNING,
+        delete=False) as output:
+
+    # Send our notification
+    apobj.notify(title="hello", body="world")
+
+    # At this point of our code, we can have a look at our output
+    # to see all of the logging that surrounded our notification(s)
+    # Note that `output` is a File object because we specified the `path` above
+    print(output.read())
+
+# tmp/apprise.persistent will exist still on disk at this point
+```
+
+## Class Details
+
+- By default if no `level=` is specified, then the log level you set globally in your program is used.
