 The Emscripten-forge recipe at https://github.com/emscripten-forge/recipes needs to be updated with the new version number and SHA checksum. An Emscripten-forge bot runs once a day and will identify the new github release and create a PR to update the recipe. Wait for this to happen, and if the tests pass and no further changes are required, the PR can be approved and merged.
 
-After the PR is merged to `main`, the recipe will be rebuilt and uploaded to https://prefix.dev/channels/emscripten-forge-dev/packages/git2cpp, which should only take a few minutes.

 Any subsequent `cockle` or JupyterLite `terminal` deployments that are rebuilt will download and use the latest `git2cpp` WebAssembly package.

+# Overview
+
+`git2cpp` is a C++ wrapper of [libgit2](https://libgit2.org/) to provide a command-line interface
+(CLI) to `git` functionality. The intended use is in WebAssembly in-browser terminals (the
+[cockle](https://github.com/jupyterlite/cockle) and
+[JupyterLite terminal](https://github.com/jupyterlite/terminal) projects) but it can be compiled and
+used on any POSIX-compliant system.
+
+The Help pages here are generated from the `git2cpp` command and subcommands to show the
+functionality that is currently supported. If there are features missing that you would like to use,
+please create an issue in the [git2cpp github repository](https://github.com/QuantStack/git2cpp).

+# Environment variables
+
+
+## In all builds
+
+The following four environment variables should be set for `git2cpp commit` and `git2cpp merge`
+subcommands. The use of `git2cpp config` instead is partially supported and will be improved in
+time.
+
+`GIT_AUTHOR_EMAIL`
+: The email for the "author" field.
+
+`GIT_AUTHOR_NAME`
+: The human-readable name in the "author" field.
+
+`GIT_COMMITTER_EMAIL`
+: The email for the "committer" field.
+
+`GIT_COMMITTER_NAME`
+: The human-readable name for the "committer" field.
+
+
+## In WebAssembly build only
+
+(git_cors_proxy)=
+`GIT_CORS_PROXY`
+: In-browser remote `git2cpp` operations such as `clone`, `fetch` and `push` usually require use of
+  a [CORS proxy server](cors_proxy). Use this environment variable to specify how the target URL is
+  encoded into the CORS proxy URL, details of which depend on how the CORS proxy server is
+  implemented.
+
+  The `GIT_CORS_PROXY` should contain the URL of the CORS proxy itself, followed by a number of
+  substitutions which are denoted by curly braces. To illustrate the substitutions, assume that the
+  `git2cpp` command is for the repository at `https://github.com/organisation/repository`.
+
+  Substitutions:
+
+  - `{host}` is replaced by `github.com`
+  - `{path}` is replaced by `/organisation/repository/` followed by extra information that depends
+    on details of the `git2cpp` operation being performed
+  - `{protocol}` is replaced by `https:`
+  - `{url}` is equivalent to `{protocol}//{host}{path}`
+  - `{api_key}` is replaced by the value of environment variable `GIT_CORS_PROXY_API_KEY` if it is
+    set.
+
+  If no substitutions are specified then `{url}` is appended.
+
+  All of the substitutions except `{api_key}` have an `:encode` variant such as `{url:encode}`
+  that passes the argument through the
+  [encodeURIComponent](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent)
+  JavaScript function, which some CORS proxies require.
+
+  You can verify the actual URL used for requests in the Network tab of your browser's Developer

 # Overview
 
 `git2cpp` is a C++ wrapper of [libgit2](https://libgit2.org/) to provide a command-line interface
-(CLI) to `git` functionality. The intended use is in WebAssembly in-browser terminals (the
-[cockle](https://github.com/jupyterlite/cockle) and
-[JupyterLite terminal](https://github.com/jupyterlite/terminal) projects) but it can be compiled and
+(CLI) to `git` functionality. The intended use is in WebAssembly in-browser terminals (see the
+[cockle](https://github.com/jupyterlite/cockle),
+[JupyterLite terminal](https://github.com/jupyterlite/terminal) and
+[Notebook.link](https://notebook.link) projects) but it can be compiled and
 used on any POSIX-compliant system.
 
 The Help pages here are generated from the `git2cpp` command and subcommands to show the
 functionality that is currently supported. If there are features missing that you would like to use,
 please create an issue in the [git2cpp github repository](https://github.com/QuantStack/git2cpp).
 
+The Appendix contains additional information on [Environment variables](env_vars.md) used in
+`git2cpp` and about the behaviour of the [WebAssembly build](wasm_build.md).

+# WebAssembly build
+
+The in-browser WebAssembly build of `git2cpp` is intended to behave as similar as possible to other
+builds but there are some differences when remotely accessing remote servers, in particular with
+blocking requests and the requirement for a CORS proxy server.
+
+
+## Blocking requests
+
+Remote `git2cpp` requests in non-WebAssembly builds are progressive and feedback is provided as the
+data is streamed back from the remote. But in WebAssembly builds such remote requests are blocking
+and no feedback can be provided until the entire response is received back from the remote.
+This can be a long time to wait without feedback, and if there is an error such that a response is
+not received it could block forever, leaving the in-browser terminal unusable.
+
+Hence the WebAssembly build limits http(s) requests with a timeout that defaults to 10 seconds.
+This timeout can be increased using the [`GIT_HTTP_TIMEOUT` environment variable](git_http_timeout).
+
+In addition, when a `git2cpp` response is received that is larger than 10 MB, a prompt is presented
+to the user to confirm whether to proceed to unpack the response or not. Note that the size of the
+response may be smaller or larger than the size of the directory structure it unpacks to.
+
+
+(cors_proxy)=
+## CORS proxy server
+
+The fetching of resources in a browser from one domain to another is often limited by a browser
+security feature called
+[Cross-Origin Resource Sharing](https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/CORS)
+(CORS). For this to be allowed the target domain must indicate it is happy to accept cross-origin
+requests by adding certain headers to `https` responses. Most git servers such as `github.com` do
+not add these headers, so a `git2cpp clone` from `github.com` will fail with a CORS error if run
+from within a browser whereas there is no such limitation if run from a terminal of a real computer.
+
+The solution to this problem is to use a separate CORS proxy server. The `git2cpp` remote request is
+sent to this intermediate server which send the request to the target server and as this request is
+coming from outside a browser it is not subject to CORS restrictions. The proxy receives the
+response from the target server and adds the required CORS headers before returning it to `git2cpp`.
+
+Various public CORS proxy servers are available for use or you serve your own. It can be useful to
+serve your own on `localhost` when experimenting to confirm that everything works as expected
+before moving on to a more complex solution. Be aware that the CORS proxy server is able to read the
+content of your request so be careful if you are using authentication tokens.
+
+The [`GIT_CORS_PROXY` environment variable](git_cors_proxy) is used to specify how the target URL is
+encoded in the CORS proxy URL.
+
+### Example running a local CORS proxy server
+
+If you are running a local [cockle](https://github.com/jupyterlite/cockle) or
+[JupyterLite terminal](https://github.com/jupyterlite/terminal) deployment you can also run a local
+CORS proxy such as [CORS Anywhere](https://github.com/Rob--W/cors-anywhere) to test it out.
+In a separate terminal on your host machine on which you have `nodejs` available, `cd` to a new
+clean directory, and download and run the CORS proxy server using:
+
+```js
+npm install cors-anywhere
+HOST=localhost PORT=8881 node node_modules/cors-anywhere/server.js
+```
+
+This will start the CORS proxy server listening on `http://localhost:8881/`. To use this in your
+local `cockle` or `JupyterLite terminal` deployment in your browser set the `CORS_PROXY_URL` to be
+```bash
+export GIT_CORS_PROXY=http://localhost:8881/
+```
+and then try a `git2cpp clone` using something like:
+```bash
+git2cpp clone https://github.com/some-organisation/some-repository
+```
+
+### Example using a public CORS proxy server
+
+There is a public instance of [CORS Anywhere](https://github.com/Rob--W/cors-anywhere) available at
+`https://cors-anywhere.herokuapp.com/`. This can be used for demonstration purposes but it requires
+an explicit opt-in and your access will be time-limited. To request temporary access go to
+`https://cors-anywhere.herokuapp.com/` and follow the instructions there.
+
+Once you have access, you can try this out in one of the public deployments such as those at
+[https://jupyterlite.github.io/cockle](https://jupyterlite.github.io/cockle) or
+[https://jupyterlite.github.io/terminal](https://jupyterlite.github.io/terminal).
+
+Set the `CORS_PROXY_URL` to be
+```bash
+export GIT_CORS_PROXY=https://cors-anywhere.herokuapp.com/
+```
+and then try a `git2cpp clone` using something like:
+```bash
+git2cpp clone https://github.com/some-organisation/some-repository
+```
