-<h1>Welcome to depell</h1>
-<p>
-	Depell (dependency hell) is a simple "social" media site best compared to twitter, except that all you can post is
-	<a href="https://git.ablecorp.us/AbleOS/holey-bytes">hblang</a> code with no comments allowed. Instead of likes you
-	run the program, and instead of retweets you import the program as dependency. Run counts even when ran indirectly.
-</p>
-
-<p>
-	The backend only serves the code and frontend compiles and runs it locally. All posts are immutable.
-</p>
-
-<h2>Security?</h2>
-<p>
-	All code runs in WASM (inside a holey-bytes VM until hblang compiles to wasm) and is controlled by JavaScript. WASM
-	cant do any form of IO without going trough JavaScript so as long as JS import does not allow wasm to execute
-	arbitrary JS code, WASM can act as a container inside the JS.
-</p>

+
+## Enforced Political Views
+
+- worse is better
+- less is more
+- embrace `unsafe {}`
+- adhere `macro_rules!`
+- pessimization == death (put in `std::pin::Pin` and left with hungry crabs)
+- importing external dependencies == death (`fn(dependencies) -> ExecutionStrategy`)
+- above sell not be disputed, discussed, or questioned
+
+## What hblang is
+
+Holey-Bytes-Language (hblang for short) (*.hb) is the only true language targeting hbvm byte code. hblang is low level, manually managed, and procedural. Its rumored to be better then writing hbasm and you should probably use it for complex applications.
+
+## What hblang isnt't
+
+hblang knows what it isn't, because it knows what it is, hblang computes this by sub...
+
+
+## Examples
+
+Examples are also used in tests. To add an example that runs during testing add:
+<pre>
+#### &lt;name&gt
+```hb
+&lt;example&gt
+```
+</pre>
+and also:
+```rs
+<name> => README;
+```
+to the `run_tests` macro at the bottom of the `src/codegen.rs`.
+
+### Tour Examples

+- `@use(<string>)`: imports a module based of string, the string is passed to a loader that can be customized, default loader uses following syntax:
+	- `((rel:|)(<path>)|git:<git-addr>:<path>)`: `rel:` and `''` prefixes both mean module is located at `path` relavive to the current file, `git:` takes a git url without `https://` passed as `git-addr`, `path` then refers to file within the repository
+- `@TypeOf(<expr>)`: results into literal type of whatever the type of `<expr>` is, `<expr>` is not included in final binary
+- `@as(<ty>, <expr>)`: hint to the compiler that  `@TypeOf(<expr>) == <ty>`
+- `@intcast(<expr>)`: needs to be used when conversion of `@TypeOf(<expr>)` would loose precision (widening of integers is implicit)
+- `@sizeof(<ty>), @alignof(<ty>)`: I think explaining this would insult your intelligence
+- `@bitcast(<expr>)`: tell compiler to assume `@TypeOf(<expr>)` is whatever is inferred, so long as size and alignment did not change
+- `@eca(<ty>, ...<expr>)`: invoke `eca` instruction, where `<ty>` is the type this will return and `<expr>...` are arguments passed to the call
