 ## Frontend dependencies ##
 
 [//]: # ( from https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions)
 
 Install Tracim and its dependencies:
 
-    cd tracim && python setup.py develop && cd -
-    pip install -r install/requirements.txt
+    cd tracim/
+    python setup.py develop
+    pip install -r ../install/requirements.txt
 
 ## Configuration files ##
 
 Create configuration files for a development environment and for `WsgiDAV`:
 
-    cp tracim/development.ini.base tracim/development.ini
-    cp tracim/wsgidav.conf.sample tracim/wsgidav.conf
+    cp development.ini.base development.ini
+    cp wsgidav.conf.sample wsgidav.conf

     gearbox serve --reload --debug
 
     Starting HTTP server on http://0.0.0.0:8080
 
 You can now enter the application at
-[http://localhost:8080](http://localhost:8080) and login with admin user.
+[http://localhost:8080](http://localhost:8080) and login with admin user:
 
- * user : admin@admin.admin
- * password : admin@admin.admin
+ * user : `admin@admin.admin`
+ * password : `admin@admin.admin`
 
 If admin user not created yet, execute following command:
