+### [Ebrowser](https://github.com/torappinfo/ebrowser): keyboard-friendly minimal suckless web browser
+Ebrowser is designed with the philosophy of [Android uweb browser](https://github.com/torappinfo/uweb) ([gitlab](https://gitlab.com/jamesfengcao/uweb)).
+
+- lightweight (less than 20k bytes) without bundled electron.
+- much less memory footprint than edge/chrome browser and highly performant.
+- keyboard friendly with vim-style keymaps and command line support in address bar.
+- [global redirection](https://uweb.surge.sh/en/redirect/index.html#) to bypass censorship.
+- user scripts at will. Ex. pressing "tr" to translate the page (need mapkeys.json config).
+- customizable.
+
+Note: Usually electron apps are heavyweight as they use browsers for simple things. Ebrowser uses core chromium effectively and very lightweight. Recommend to install electron separately.
+
+#### Installing (for Windows, MacOS and Linux)
+##### Install with prebuilt binaries
+You can find prebuilt binaries [here](https://github.com/torappinfo/ebrowser/releases).
+
+##### Install with nodejs
+
+    npm install electron
+    npm install ebrowser
+
+Run ebrowser
+
+    electron ~/node_modules/ebrowser
+
+Later on, you can run "npm install electron" to update electron/chromium or "npm install ebrowser" to update ebrowser independently.
+
+##### Update app quickly without updating chromium
+Pressing "Alt" to show the menu bar and choose "Check for updates" under "Help". OR
+
+Type ":update" in the address bar and press "enter" key to update.
+
+Mirror urls could be used like ":update https://uwebzh.netlify.app/misc/ebrowser". All the mirrors listed on [uweb browser](https://uwebzh.netlify.app/en/readme/index.html) could be used. The update url needs to be changed accordingly to be the folder "misc/ebrowser" under the mirror site root url.
+
+#### Key shortcuts
+- CTRL+C: stop loading
+- CTRL+G: address bar to show page url
+- CTRL+L: focus to address bar
+- CTRL+T: new Tab
+- CTRL+SHIFT+T: restore closed Tab
+- CTRL+TAB: switch to next tab
+- CTRL+SHIFT+TAB: switch to previous tab
+- CTRL+W: close Tab
+- ALT+<-: go backward
+- ALT+->: go forward
+- CTRL+SHIFT+R: enable global redirection ("gredirect.json")
+- CTRL+R: disable global redirection
+- ESC: remove focus. similar to vi normal mode.
+- F1: Help
+- F5: page refresh/reload
+- F12: devtools
+
+#### Address bar commands
+- "/" for find-in-page
+- ":" for address bar commands
+  - ac [bookmark/history path w/o ext] : load ".rec" file for autocomplete.
+  - b [bookmarkfilename w/o ext] : bookmark current page in file.
+  - bml [filename w/o extension]: load/execute the javascript file.
+  - cert : allow invalid certificates w/o arguments, otherwise restore to default.
+  - clear : the arguments could be
+    - cache : clear cache
+    - dns : clear dns cache
+    - storage: clear site storage data.
+    - {[options](https://www.electronjs.org/docs/latest/api/session#sescleardataoptions)}
+  - ext [extension path]: load unpacked Chrome extension.
+  - gr [gredirect index]: global redirection with corresponding index. Use the first global redirection url if no argument. Disable global redirection with any index out of the range.
+  - js [js code] : execute JS code at OS level. Note: "javascript:..." is special url and thus works in the current web page, while ":js ..." commands can do any OS operations. 
+  - nc/uc : No Cookie forwarding/Use Cookie forwarding with global redirection.
+  - nh/uh for No/Use url history.
+  - nj/uj for No/Use external Javascript files.
+  - nr/ur for No/Use "redirect.json" for domain redirection.
+  - np : no proxy.
+  - up [proxyName] : use proxy. privous proxy or the first proxy in proxy.json w/o [proxyName]. ":up" command also disables global and domain redirections, which are not restored by ":np".
+  - ua [useragentName] : set user agent for future tabs. default user agent w/o arguments.
+  - update [updateurl] : update the app. updateurl is optional.
+  - pdf [filename w/o extension] {[options](https://www.electronjs.org/docs/latest/api/web-contents#contentsprinttopdfoptions)} : print to PDF file. All arguments are optional; empty option "{}" to capture long screenshot as vector graphics.
+- "!" address bar commands  
+  "!xx ..." evaluates "xx.js" with the whole text as arguments[0].
+  
+#### Commands in no-focus mode (this mode is similar to vi Normal mode)
+Pressing "ESC" to enter no-focus mode if not sure.
+- ":" for address bar commands
+- "/" for find-in-page with address bar
+- "!" for "!" address bar commands
+
+The other commands are defined in "mapkeys.json", which will map keys to address bar commands.
+
+#### Configuration files
+- "config": lines of address bar commands.
+- "search.json": search engines as shortcut-queryUrl pairs.
+- "default.autoc": predefined strings for address bar auto completion.
+- "gredirect.json": global redirection urls as array of urls
+- "redirect.json": domain-replacementDomain pairs, default to be applied.
+- "mapkeys.json": keys-addressbarCommands pairs. The addressbar commands are multiple lines of address bar command separated by "\n".
+- "proxy.json": name-[ProxyConfig](https://www.electronjs.org/docs/latest/api/structures/proxy-config) pairs
+- "uas.json" : name-useragent pairs
+
+#### Javascript at three levels
+- Web page: urls like "javascript:" or bookmarklet command ":bml" run in web page.
+- Browser (or renderer process) : "!xx" evaluates "xx.js", which could manipulate address bar etc.
+- OS level (or main process) : ":js" to execute the following js code with all OS APIs available.
+
+#### New usages
+- Vector designing with web tech to replace Adobe Illustrator/Inkscape.
+  - Design with web tech.
+  
+  - Printing to pdf with customized paper size.
+  - Magnify the pdf paper size to the required size.
+
+  OR
+  
+  - Adjust window width and use addressbar command line ":Pdf {}" to export vector graphics.
+  - Use imageMagick to convert to any other vector graphics format.
+
+#### License
+You can copy or modify the code/program under the terms of the GPL3.0 or later versions.
