 Congrats! The pre-requisites are ready.
 
 ## Set-up development environment (web app)
+
 The basic idea is replacing the `clojure` commands in [package.json](https://github.com/logseq/logseq/blob/master/package.json) to `clj`.  
-Go to your cloned Logseq repo. Then install dependencies, execute the `clj` equivalent of `yarn watch` via doing the `gulp`'s job manually (as it's not available on Windows). Refer [THIS](#an-example-of-setting-up-proxy-in-powershell) if you want to setup proxy in `PowerShell`.
-* copy files in `resources` to `static`
-* ```
-  yarn
-  clj -M:cljs watch app electron
+Go to your cloned Logseq repo. Then install dependencies, execute the `clj` equivalent of `yarn watch`. Refer [THIS](#an-example-of-setting-up-proxy-in-powershell) if you want to setup proxy in `PowerShell`.
+
+* Copy files in `resources` to `static`
+
+* Compile static assets(css, icons...)
   ```
-* ```
-  yarn css:watch
+  yarn add --dev gulp
+  yarn
+  yarn gulp:watch
   ```
 
+* Open another powershell window, and run `yarn cljs:watch`. Clojure CLI will pull dependencies from Maven and Clojars, build the app and start the development server. Refer [THIS](#set-up-clojure-cli-repository-mirror) if your network access to Maven and Clojars is unstable.
+
 Now you can access the app via `http://localhost:3001` and all changes to the code will be watched.
 
 ## Set-up development environment (desktop)
 To run the desktop app in development mode, after setting up web app development environment, run following commands which are equivalent to `yarn dev-electron-app`:
-* ```
-  cd static
-  yarn
-  yarn electron:dev
-  ```
+
+```
+cd static
+yarn
+yarn electron:dev
+```
+
 The desktop app should pop-up on your screen.
 
+During the build process `node-gyp` may complain that it cannot find Visual Studio. Try building the app in Developer Powershell for VS(shipped with Visual Studio). If this does not work for you, [This issue](https://github.com/nodejs/node-gyp/issues/2203) may be helpful.

 ## An example of setting up proxy in PowerShell
 ```
 $env:GLOBAL_AGENT_HTTPS_PROXY='http://<proxy-host>:<proxy-port>'
 $env:ELECTRON_GET_USE_PROXY='true'
 $env:HTTPS_PROXY='http://<proxy-host>:<proxy-port>'
 $env:HTTP_PROXY='http://<proxy-host>:<proxy-port>'
-```
+```
+
+## Set up Clojure CLI repository mirror
+
+add the following pair to `deps.edn`:
+
+```
+:mvn/repos {
+  "central" {:url "https://maven.aliyun.com/repository/public"}
+  "clojars" {:url "https://mirrors.tuna.tsinghua.edu.cn/clojars"}
+}
+```
+
+The mirrors above are friendly to Chinese developers(with bad network), developers with self-hosted repositories can use their own services.
