+* Initial setup
+
+Most ~mu~ commands and ~mu4e~ require setting up the database, which is needed only
+once. For this, there is the ~mu init~ command. See its manpage for all the
+details, but could look something like:
+
+#+begin_example
+$ mu init --maildir=~/Maildir          \
+    --personal-address=jim@example.com \
+    --personal-address=bob@example.com \
+    --ignored-address='.*reply*.'
+#+end_example
+
+This creates your database, specifies some of your personal addresses, and some
+addresses (a regular expression) that should be ignored from the contacts-cache
+used for address-autocompletion in ~mu4e~.
+
+After this step, we can index our maildir:
+#+begin_example
+$ mu index
+#+end_example
+The first time you do this, it can take a few minutes, depending on how many
+messages you have. Afterwards, you can run ~mu index~ e.g., after retrieving
+messages from a remote server.
+
+After that has completed you can try to find some messages with some simple
+queries:
+#+begin_example
+$ mu find hello
+#+end_example
