### Via Gajim PluginManager
Install the current stable version via the Gajim PluginManager. You *need* Gajim
version *0.16.5* or higher. If your package manager does not provide an up to date version
you can visit gajim.org for further install instructions.
**NOTE:** You *have* to install `python-axolotl` via PackageManager or depending on your setup you might
want to use `pip2` as Gajim is using python2.7.
if you still have problems, we have written down the most common problems [here](https://github.com/omemo/gajim-omemo/wiki/It-doesnt-work,-what-should-i-do%3F-(Linux))
## Running
Enable *OMEMO Multi-End Message and Object Encryption* in the Plugin-Manager.
If your contact supports OMEMO you should see a new orange fish icon in the chat window.
Encryption will be enabled by default for contacts that support OMEMO.
If you open the chat window, the Plugin will tell you with a green status message if its *enabled* or *disabled*.
If you see no status message, your contact doesnt support OMEMO.
(**Beware**, every status message is green. A green message does not mean encryption is active. Read the message !)
You can also check if encryption is enabled/disabled, when you click on the OMEMO icon.
When you send your first message the Plugin will query your contacts encryption keys and you will
see them in a readable fingerprint format in the fingerprint window which pops up.
you have to trust at least **one** fingerprint to send messages.
you can receive messages from fingerprints where you didnt made a trust decision, but you cant
receive Messages from *not trusted* fingerprints
## Groupchat
Groupchat works only in rooms that are
- non-anonymous
- members-only
- works only with contacts that you have in your roster
## Filetransfer
For Filetransfer use the **httpupload** plugin.
For decrypting and showing pictures in chat use the **url_image_preview** plugin.
If you want to use these plugins together with *OMEMO* you have to install the `python-cryptography` package
## Performance
If you experience lag when sending a message, install `python-cryptography`
If that doesnt help, you can convert your database to WAL mode with
```
sqlite3 omemo_your@jid.com.db
PRAGMA journal_mode=WAL
```
Warning: This mode could lead to data loss if Gajim crashes
## Debugging
To see OMEMO related debug output start Gajim with the parameter `-l
gajim.plugin_system.omemo=DEBUG`.
## Hacking

contribute clone the git repository into your Gajim's plugin directory.
