+## Description Import-Export app
+ProtonMail Import-Export app for importing and exporting messages.
+
+To transfer messages, firstly log in using your ProtonMail credentials.
+For import, expand your account, and pick the address to which to import
+messages from IMAP server or local EML or MBOX files. For export, pick
+the whole account or only a specific address. Then, in both cases,
+configure transfer rules (match source and target mailboxes, set time
+range limits and so on) and hit start. Once the transfer is complete,

 ## Environment Variables
 
 ### Bridge application
 - `BRIDGESTRICTMODE`: tells bridge to turn on `bbolt`'s "strict mode" which checks the database after every `Commit`. Set to `1` to enable.
 
 ### Dev build or run
+- `APP_VERSION`: set the bridge app version used during testing or building
 - `PROTONMAIL_ENV`: when set to `dev` it is not using Sentry to report crashes
-- `VERBOSITY`: set log level used during test time and by the makefile.
-- `VERSION`: set the bridge app version used during testing or building.
+- `VERBOSITY`: set log level used during test time and by the makefile
 
 ### Integration testing
 - `TEST_ENV`: set which env to use (fake or live)
+- `TEST_APP`: set which app to test (bridge or ie)
 - `TEST_ACCOUNTS`: set JSON file with configured accounts
 - `TAGS`: set build tags for tests
 - `FEATURES`: set feature dir, file or scenario to test
 
 
+## Files
+### Database
+The database stores metadata necessary for presenting messages and mailboxes to an email client:
+- Linux: `~/.cache/protonmail/bridge/<cacheVersion>/mailbox-<userID>.db` (unless `XDG_CACHE_HOME` is set, in which case that is used as your `~`)
+- macOS: `~/Library/Caches/protonmail/bridge/<cacheVersion>/mailbox-<userID>.db`
+- Windows: `%LOCALAPPDATA%\protonmail\bridge\<cacheVersion>\mailbox-<userID>.db`
 
+### Preferences
+User preferences are stored in json at the following location:
+- Linux: `~/.cache/protonmail/bridge/<cacheVersion>/prefs.json` (unless `XDG_CACHE_HOME` is set, in which case that is used as your `~`)
+- macOS: `~/Library/Caches/protonmail/bridge/<cacheVersion>/prefs.json`
+- Windows: `%LOCALAPPDATA%\protonmail\bridge\<cacheVersion>\prefs.json`
+
+### IMAP Cache
+The currently subscribed mailboxes are held in a json file:
+- Linux: `~/.cache/protonmail/bridge/<cacheVersion>/user_info.json` (unless `XDG_CACHE_HOME` is set, in which case that is used as your `~`)
+- macOS: `~/Library/Caches/protonmail/bridge/<cacheVersion>/user_info.json`
+- Windows: `%LOCALAPPDATA%\protonmail\bridge\<cacheVersion>\user_info.json`
+
+### Lock file
+Bridge utilises an on-disk lock to ensure only one instance is run at once. The lock file is here: 
+- Linux: `~/.cache/protonmail/bridge/<cacheVersion>/bridge.lock` (unless `XDG_CACHE_HOME` is set, in which case that is used as your `~`)
+- macOS: `~/Library/Caches/protonmail/bridge/<cacheVersion>/bridge.lock`
+- Windows: `%LOCALAPPDATA%\protonmail\bridge\<cacheVersion>\bridge.lock`
+
+### TLS Certificate and Key
+When bridge first starts, it generates a unique TLS certificate and key file at the following locations:
+- Linux: `~/.config/protonmail/bridge/{cert,key}.pem` (unless `XDG_CONFIG_HOME` is set, in which case that is used as your `~/.config`)
+- macOS: `~/Library/ApplicationSupport/protonmail/bridge/{cert,key}.pem`
+- Windows: `%APPDATA%\protonmail\bridge\{cert,key}.pem`

+Description:
+ProtonMail Import-Export was not able to establish a secure connection to Proton
+servers due to a TLS certificate error. This means your connection may
+potentially be insecure and susceptible to monitoring by third parties.
+
+Recommendation:
+* If you trust your network operator, you can continue to use ProtonMail
+  as usual.
+* If you don't trust your network operator, reconnect to ProtonMail over a VPN
+  (such as ProtonVPN) which encrypts your Internet connection, or use
+  a different network to access ProtonMail.
